Constructor Detail

SaxonAssign

public SaxonAssign()
Method Detail

isInstruction

public boolean isInstruction()
Determine whether this node is an instruction.

Overrides:
isInstruction in class StyleElement
Returns:
true - it is an instruction

isAssignable

public boolean isAssignable()
Description copied from class: XSLGeneralVariable
Test whether it is permitted to assign to the variable using the saxon:assign extension element. This will only be true if the extra attribute saxon:assignable="yes" is present.

Overrides:
isAssignable in class XSLGeneralVariable

allowsAsAttribute

protected boolean allowsAsAttribute()
Overrides:
allowsAsAttribute in class XSLGeneralVariable

validate

public void validate()
              throws javax.xml.transform.TransformerConfigurationException
Description copied from class: StyleElement
Check that the stylesheet element is valid. This is called once for each element, after the entire tree has been built. As well as validation, it can perform first-time initialisation. The default implementation does nothing; it is normally overriden in subclasses.

Overrides:
validate in class XSLGeneralVariable
javax.xml.transform.TransformerConfigurationException

compile

public Instruction compile()
                    throws javax.xml.transform.TransformerConfigurationException
Description copied from class: StyleElement
Compile the instruction on the stylesheet tree into an executable instruction for use at run-time.

Specified by:
compile in class StyleElement
Returns:
either an Instruction, or null (indicating a no-op).
javax.xml.transform.TransformerConfigurationException
