Method Details
-
prepareAttributes
Description copied from class:StyleElement
Set the attribute list for the element. This is called to process the attributes (note the distinction from processAttributes in the superclass). Must be supplied in a subclass- Overrides:
prepareAttributes
in classXSLGeneralVariable
- Throws:
XPathException
-
isInstruction
public boolean isInstruction()Determine whether this node is an instruction.- Overrides:
isInstruction
in classXSLVariableDeclaration
- Returns:
- true - it is an instruction (well, it can be, anyway)
-
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.- Specified by:
getRequiredType
in classXSLVariableDeclaration
-
compile
Compile: used only for global variables. This method 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
-
compileLocalVariable
- Throws:
XPathException
