Member Function Documentation

getHead()

XdmItem * XdmItem::getHead ( )

virtual

Get the first item in the sequence

Returns

XdmItem or null if sequence is empty

Reimplemented from XdmValue.

getStringValue()

const char * XdmItem::getStringValue ( )

virtual

Get the string value of the item. For a node, this gets the string value of the node. For an atomic value, it has the same effect as casting the value to a string. In all cases the result is the same as applying the XPath string() function.

For atomic values, the result is the same as the result of calling toString. This is not the case for nodes, where toString returns an XML serialization of the node.

Returns

the result of converting the item to a string.

Deprecated:

the SaxonProcessor argument. It has been removed from release version 1.2.1

Reimplemented in XdmNode, and XdmAtomicValue.

getType()

XDM_TYPE XdmItem::getType ( )

virtual

Get the type of the object

Reimplemented from XdmValue.

Reimplemented in XdmNode, and XdmAtomicValue.

getUnderlyingValue()

jobject XdmItem::getUnderlyingValue ( )

virtual

Get Java XdmValue object.

Returns

jobject - The Java object of the XdmValue in its JNI representation

Reimplemented from XdmValue.

Reimplemented in XdmNode.

itemAt()

XdmItem * XdmItem::itemAt ( int  n )

virtual

Get the n'th item in the value, counting from zero.

Parameters

n	the item that is required, counting the first item in the sequence as item zero

Returns

the n'th item in the sequence making up the value, counting from zero return NULL if n is less than zero or greater than or equal to the number of items in the value return NULL if the value is lazily evaluated and the delayed evaluation fails with a dynamic error.

Reimplemented from XdmValue.

size()

int XdmItem::size ( )

virtual

Get the number of items in the sequence

Reimplemented from XdmValue.
