Constructor & Destructor Documentation

XdmValue::XdmValue ( )

inline

A default Constructor. Create a empty value

XdmValue::XdmValue

(

const XdmValue &

other

)

A copy constructor.

Parameters

val	- Xdmvalue

XdmValue::XdmValue

(

jobject

val

)

A Constructor. Wrap an Java XdmValue object.

Parameters

val	- Java XdmValue object

Member Function Documentation

void XdmValue::addUnderlyingValue

(

jobject

val

)

Add an Java XdmValue object to the sequence. See methods the functions in SaxonCXPath of the C library

Parameters

val	- Java object

void XdmValue::addXdmItem

(

XdmItem *

val

)

Add an XdmItem to the sequence. See methods the functions in SaxonCXPath of the C library

Parameters

val	- XdmItem object

XdmValue* XdmValue::addXdmValueWithType	(	const char *	tStr,
		const char *	val
	)

Constructor. Create a value from a collection of items

Parameters

val	- Xdmvalue Constructor. Create a value from a collection of items
val	- Xdmvalue Add an XdmItem to the sequence. This method is designed for the primitive types.
type	- specify target type of the value
val	- Value to convert

XdmItem * XdmValue::getHead ( )

virtual

Get the first item in the sequence

Returns

XdmItem or null if sequence is empty

Reimplemented in XdmItem.

XDM_TYPE XdmValue::getType ( )

virtual

Get the type of the object

Reimplemented in XdmNode, XdmItem, and XdmAtomicValue.

jobject XdmValue::getUnderlyingValue ( )

virtual

Get Java XdmValue object.

Returns

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

Reimplemented in XdmNode, and XdmItem.

XdmItem * XdmValue::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 in XdmItem.

int XdmValue::size ( )

virtual

Get the number of items in the sequence

Reimplemented in XdmItem.

Member Data Documentation

char* XdmValue::valueType

protected

Cached. The type of the XdmValue

int XdmValue::xdmSize

protected
