Method Details

compile

public Expression compile(Executable exec)
            throws XPathException
Compile: used only for global variables. This method ensures space is available for local variables declared within this global variable
Overrides:
compile in interface StyleElement

compileLocalVariable

public Expression compileLocalVariable(Executable exec)
            throws XPathException

getRequiredType

public SequenceType getRequiredType()
Get the static type of the variable. This is the declared type, unless the value is statically known and constant, in which case it is the actual type of the value.
Overrides:
getRequiredType in interface XSLVariableDeclaration

isInstruction

public boolean isInstruction()
Determine whether this node is an instruction.
Overrides:
isInstruction in interface XSLVariableDeclaration
Returns:
true - it is an instruction (well, it can be, anyway)

prepareAttributes

public void prepareAttributes()
            throws XPathException
Overrides:
prepareAttributes in interface XSLGeneralVariable
