allowsValue
protected boolean allowsValue()
- Overrides:
allowsValue
in classXSLGeneralVariable
-
allowsRequired
protected boolean allowsRequired()
- Overrides:

allowsTunnelAttribute
protected boolean allowsTunnelAttribute()

validate
public void validate() throws XPathException
Description copied from class:XSLVariableDeclaration
Check that the variable is not already declared, and allocate a slot number- Overrides:
validate
in classXSLVariableDeclaration
- Throws:
XPathException
-
compile
public Expression compile(Executable exec) throws XPathException
Compile: this ensures space is available for local variables declared within this global variable- Specified by:
compile
in classStyleElement
- Returns:
- either a ComputedExpression, or null. The value null is returned when compiling an instruction that returns a no-op, or when compiling a top-level object such as an xsl:template that compiles into something other than an instruction.
- Throws:
XPathException
-
getRequiredType
public SequenceType getRequiredType()
Get the static type of the parameter. This is the declared type, because we cannot know the actual value in advance.- Specified by:
getRequiredType
in classXSLVariableDeclaration
