Methods

Modifier and Type	Method and Description
java.lang.String	getSchemeData() Returns a String containing the scheme data of the PointerPart.
java.lang.String	getSchemeName() Returns a String containing the scheme name of the PointerPart or the name of the ShortHand Pointer.
boolean	isChildFragmentResolved() Returns true if the XPointer expression resolves to a non-element child of the current resource fragment.
boolean	isFragmentResolved() Returns true if the XPointer expression resolves to a resource fragment specified as input else returns false.
void	parseXPointer(java.lang.String part) Provides scheme specific parsing of a XPointer expression i.e.
boolean	resolveXPointer(org.apache.xerces.xni.QName element, org.apache.xerces.xni.XMLAttributes attributes, org.apache.xerces.xni.Augmentations augs, int event) Evaluates an XML resource with respect to an XPointer expressions by checking if it's element and attributes parameters match the criteria specified in the xpointer expression.
void	setSchemeData(java.lang.String schemeData) Sets the scheme data of the PointerPart.
void	setSchemeName(java.lang.String schemeName) Sets the scheme name of the PointerPart or the ShortHand Pointer name.

Method Detail

parseXPointer

void parseXPointer(java.lang.String part)
                   throws org.apache.xerces.xni.XNIException

Provides scheme specific parsing of a XPointer expression i.e. the PointerPart or ShortHandPointer.

Parameters:

part - A String representing the PointerPart or ShortHandPointer.

Throws:

org.apache.xerces.xni.XNIException - Thrown if the PointerPart string does not conform to the syntax defined by its scheme.

resolveXPointer

boolean resolveXPointer(org.apache.xerces.xni.QName element,
                      org.apache.xerces.xni.XMLAttributes attributes,
                      org.apache.xerces.xni.Augmentations augs,
                      int event)
                        throws org.apache.xerces.xni.XNIException

Evaluates an XML resource with respect to an XPointer expressions by checking if it's element and attributes parameters match the criteria specified in the xpointer expression.

Parameters:

element - - The name of the element.

attributes - - The element attributes.

augs - - Additional information that may include infoset augmentations

event - - An integer indicating 0 - The start of an element 1 - The end of an element 2 - An empty element call

Throws:

org.apache.xerces.xni.XNIException - Thrown to signal an error

isFragmentResolved

boolean isFragmentResolved()
                           throws org.apache.xerces.xni.XNIException

Returns true if the XPointer expression resolves to a resource fragment specified as input else returns false.

Returns:

True if the xpointer expression matches a fragment in the resource else returns false.

Throws:

org.apache.xerces.xni.XNIException - Thrown to signal an error

isChildFragmentResolved

boolean isChildFragmentResolved()
                                throws org.apache.xerces.xni.XNIException

Returns true if the XPointer expression resolves to a non-element child of the current resource fragment.

Returns:

True if the XPointer expression resolves to a non-element child of the current resource fragment.

Throws:

org.apache.xerces.xni.XNIException - Thrown to signal an error

getSchemeName

java.lang.String getSchemeName()

Returns a String containing the scheme name of the PointerPart or the name of the ShortHand Pointer.

Returns:

A String containing the scheme name of the PointerPart.

getSchemeData

java.lang.String getSchemeData()

Returns a String containing the scheme data of the PointerPart.

Returns:

A String containing the scheme data of the PointerPart.

setSchemeName

void setSchemeName(java.lang.String schemeName)

Sets the scheme name of the PointerPart or the ShortHand Pointer name.

Parameters:

schemeName - A String containing the scheme name of the PointerPart.

setSchemeData

void setSchemeData(java.lang.String schemeData)

Sets the scheme data of the PointerPart.

Parameters:

schemeData - A String containing the scheme data of the PointerPart.
