absolute

Moves the XQSequence's position to the given item number in this object.

If the item number is positive, the XQSequence moves to the given item number with respect to the beginning of the XQSequence. The first item is item 1, the second is item 2, and so on.If the given item number is negative, the XQSequence positions itself on an absolute item position with respect to the end of the sequence.For example, calling the method absolute(-1) positions the XQSequence on the last item; calling the method absolute(-2) moves the XQSequence to the next-to-last item, and so on. absolute(0) will position the sequence before the first item.An attempt to position the sequence beyond the first/last item set leaves the current position to be before the first item or after the last item.Calling this method on an empty sequence will return false.

afterLast

Move to the position after the last item.

beforeFirst

Moves to the position before the first item.

close

Closes the sequence and frees all resources associated with this sequence.

Closing an XQSequence object also implicitly closes all XQItem objects obtained from it. All methods other than the isClosed or close method will raise exceptions when invoked after closing the sequence. Calling close on an XQSequence object that is already closed has no effect.

count

Returns a number indicating the number of items in the sequence.

first

Moves to the first item in the sequence.

The method returns true, if it was able to move to the first item in the sequence false, otherwise. Calling this method on an empty sequence will return false.

getAtomicValue

Gets the current item as a Java String.

The current item must be an atomic value. This function casts the current item to an xs:string value according to the casting rules defined in 17.1.2 Casting to xs:string and xs:untypedAtomic, XQuery 1.0 and XPath 2.0 Functions and Operators, and then returns the value as a Java String.

getBoolean

Gets the current item as a boolean.

The current item must be an atomic value of type xs:boolean or a subtype.

getByte

Gets the current item as a byte.

The current item must be an atomic value of type xs:decimal or a subtype, and its value must be in the value space of byte.

getConnection

Gets the XQuery connection associated with this result sequence.

getDouble

Gets the current item as a double.

The current item must be an atomic value of type xs:double or a subtype.

getFloat

Gets the current item as a float.

The current item must be an atomic value of type xs:float or a subtype.

getInt

Gets the current item as an int.

The current item must be an atomic value of type xs:decimal or a subtype, and its value must be in the value space of int.

getItem

Get the current item as an immutable XQItem object.

In case of an XQResultSequence, the item is an ZorbaXQResultItem. In the case of forward only sequences, this method or any other get or write method may only be called once on the curent item.The XQItem object is dependent on the sequence from which it was created and is only valid for the duration of XQSequence lifetime. Thus, the XQSequence is closed, this XQItem object will be implicitly closed and it can no longer be used.

getItemAsStream

Read the current item as an XMLStreamReader object.

Read the current item as an XMLStreamReader object, as described in Section 12.1 Serializing an XDM instance into a StAX event stream (XMLStreamReader), XQuery API for Java (XQJ) 1.0. Note that the serialization process might fail, in which case a XQException is thrown. While the stream is being read, the application MUST NOT do any other concurrent operations on the underlying item or sequence. The operation on the stream is undefined if the underlying sequence is repositioned or the state of the underlying item or sequence is changed by concurrent operations.

getItemAsString

Serializes the current item according to the XSLT 2.0 and XQuery 1.0 serialization.

Serialization parameters, which influence how serialization is performed, can be specified. Refer to the XSLT 2.0 and XQuery 1.0 serialization and Section 12 Serialization, XQuery API for Java (XQJ) 1.0 for more information.

getItemType

Gets the type of the item.

On a forward only sequence this method can be called independent of any other get or write method. It will not raise an error if such method has been called already, nor will it affect subsequent invocations of any other get or write method.

getLong

Gets the current item as a long.

The current item must be an atomic value of type xs:decimal or a subtype, and its value must be in the value space of long.

getNode

Gets the item as a DOM node.

The current item must be a node. The type of the returned DOM node is governed by Table 7 - XQuery Node Types and Corresponding Java Object Types XQuery API for Java (XQJ) 1.0 The instance of the returned node is implementation dependent. The node may be a reference or a copy of the internal state of the item. It is advisable to make a copy of the node if the application plans to modify it.

getNodeUri

Returns the URI for this item.

If the item is a document node, then this method returns the absolute URI of the resource from which the document node was constructed. If the document URI is not available, then the empty string is returned. If the document URI is available, the returned value is the same as if fn:document-uri were evaluated on this document node. If the item is of a node kind other than document node, then the returned URI is implementation-defined. On a forward only sequence this method can be called independent of any other get or write method. It will not raise an error if such method has been called already, nor will it affect subsequent invocations of any other get or write method on the current item.

getObject

Gets the current item as an Object.

The data type of the returned object will be the Java Object type as specified in 14.4 Mapping an XQuery Atomic Value to a Java Object Type and 14.5 Mapping an XQuery Node to a Java Object Type, XQuery API for Java (XQJ) 1.0.

getPosition

Gets the current cursor position.

0 indicates that the position is before the first item and count() + 1 indicates position after the last item. A specific position indicates that the cursor is positioned on the item at that position. Use the isOnItem method to verify if the cursor is positioned on the item.Calling this method on an empty sequence will return 0.

getSequenceAsStream

Read the entire sequence starting from the current position as an XMLStreamReader object.

Read the entire sequence starting from the current position as an XMLStreamReader object, as described in Section 12.1 Serializing an XDM instance into a StAX event stream (XMLStreamReader), XQuery API for Java (XQJ) 1.0. Note that the serialization process might fail, in which case a XQException is thrown. While the stream is being read, the application MUST NOT do any other concurrent operations on the sequence. The operation on the stream is undefined if the underlying sequence position or state is changed by concurrent operations. After all items are written to the stream, the current position of the cursor is set to point after the last item. Also, in the case of forward only sequences, this method may only be called if the current item has not yet been read through any of the get or write methods.

getSequenceAsString

Serializes the sequence starting from the current position to a String.

Serializes the sequence starting from the current position to a String according to the XSLT 2.0 and XQuery 1.0 serialization. Serialization parameters, which influence how serialization is performed, can be specified. Refer to the XSLT 2.0 and XQuery 1.0 serialization and Section 12 Serialization, XQuery API for Java (XQJ) 1.0 for more information. Reading the sequence during the serialization process performs implicit next operations to read the items. After all items are written to the stream, the current position of the cursor is set to point after the last item. Also, in the case of forward only sequences, this method may only be called if the current item has not yet been read through any of the get or write methods.

getShort

Gets the current item as a short.

The current item must be an atomic value of type xs:decimal or a subtype, and its value must be in the value space of short.

getStaticCollectionManager

Returns a StaticCollectionManager.

Returns a CollectionManager responsible for all collections which are statically declared in the static context of this query (main module) or any transitively imported library module. The collection manager provides a set of functions for managing collections and their contents.

instanceOf

Checks if the item "matches" an item type.

Checks if the item "matches" an item type, as defined in 2.5.4.2 Matching an Item Type and an Item, XQuery 1.0: An XML Query Language. You can use this method to first check the type of the result before calling the specific get methods.Example -

 {.java}
   ...
   XQItemType strType = conn.createAtomicType(XQItemType.XQBASETYPE_STRING);
   XQItemType nodeType = conn.createNodeType();
 
   XQSequence result = preparedExpr.executeQuery();
   while (result.next())
   {
      // Generic check for node.. 
      if (result.instanceOf(nodeType))
         org.w3.dom.Node node = result.getNode();
      else if (result.instanceOf(strType))
         String str = result.getAtomicValue();
    }
  
 
 If either the type of the XQItemAccessor or the input XQItemType is not a built-in type, then this method is allowed to raise exception if it can NOT determine the instanceOf relationship due to the lack of the access of the XML schema that defines the user defined schema types if the XQMetaData.isUserDefinedXMLSchemaTypeSupported() method returns false. 
 Otherwise, this method must determine if the type of the XQItemAccessor is an instance of the input XQItemType. Note even if isUserDefinedXMLSchemaTypeSupported() returns false, an XQJ implementation may still be able to determine the instanceOf relationship for certain cases involving user defined schema type. For example, if the type of an XQItemAccessor is of mySchema:hatSize sequence type and the input parameter XQItemType is of item() sequence type, the return value for instanceOf relationship should always be true even though the XQJ implementation does not know the precise type information of mySchema:hatSize type defined in XML schema 'mySchema'.

isAfterLast

Checks if the current position is after the last item in the sequence.

Calling this method on an empty sequence will return false.

isBeforeFirst

Checks if the current position before the first item in the sequence.

Calling this method on an empty sequence will return false.

isClosed

Checks if the sequence is closed.

isFirst

Checks if the current position at the first item in the sequence.

Calling this method on an empty sequence will return false.

isLast

Checks if the current position at the last item in the sequence.

Calling this method on an empty sequence will return false.

isOnItem

Check if the sequence is positioned on an item or not.

Calling this method on an empty sequence will return false.

isScrollable

Checks if the sequence is scrollable.

last

Moves to the last item in the sequence.

This method returns true, if it was able to move to the last item in the sequence false, otherwise. Calling this method on an empty sequence will return false.

next

Moves to the next item in the sequence.

Calling this method on an empty sequence will return false.

previous

Moves to the previous item in the sequence.

Calling this method on an empty sequence will return false.

relative

Moves the cursor a relative number of items.

Moves the cursor a relative number of items, either positive or negative. Attempting to move beyond the first/last item in the sequence positions the sequence before/after the the first/last item. Calling relative(0) is valid, but does not change the cursor position. Note: Calling the method relative(1) is identical to calling the method next and calling the method relative(-1) is identical to calling the method previous(). Calling this method on an empty sequence will return false.

writeItem

Serializes the current item to a Writer.

Serializes the current item to a Writer according to XSLT 2.0 and XQuery 1.0 serialization. Serialization parameters, which influence how serialization is performed, can be specified. Refer to the XSLT 2.0 and XQuery 1.0 serialization and Section 12 Serialization, XQuery API for Java (XQJ) 1.0 for more information.

writeItem

Serializes the current item to a Writer.

writeItemToResult

Writes the current item to a Result.

First the item is normalized as described in XSLT 2.0 and XQuery 1.0 serialization. Subsequently it is serialized to the Result object. Note that the normalization process can fail, in which case an XQException is thrown. An XQJ implementation must at least support the following implementations:

• javax.xml.transform.dom.DOMResult
• javax.xml.transform.sax.SAXResult
• javax.xml.transform.stream.StreamResult

writeItemToSAX

Writes the current item to a SAX handler.

Note that the serialization process might fail, in which case a XQException is thrown. The specified org.xml.sax.ContentHandler can optionally implement the org.xml.sax.LexicalHandler interface. An implementation must check if the specified ContentHandler implements LexicalHandler. If the handler is a LexicalHandler comment nodes are reported, otherwise they will be silently ignored.

writeSequence
