Method Details
-
getBindingInformation
Ask whether this element contains a binding for a variable with a given name; and if it does, return the source binding information- Overrides:
getBindingInformation
in classStyleElement
- Parameters:
name
- the variable name- Returns:
- the binding information if this element binds a variable of this name; otherwise null
-
getSlotNumber
public int getSlotNumber()Get the slot number allocated to this variable (its position in the stackframe)- Returns:
- the allocated slot number
-
prepareAttributes
protected void 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- Specified by:
prepareAttributes
in classStyleElement
-
getDefaultValueExpressionSupplier
-
prepareTemplateSignatureAttributes
- Throws:
XPathException
-
validate
Description copied from class:XSLGeneralVariable
Check that the variable is not already declared, and allocate a slot number- Overrides:
validate
in classXSLGeneralVariable
- Parameters:
decl
- the declaration being validated. A single XSLVariableDeclaration object may represent multiple declarations if it appears in a stylesheet module that is included/imported more than once- Throws:
XPathException
- if any error is found during validation
-
isTunnelParam
public boolean isTunnelParam() -
isRequiredParam
public boolean isRequiredParam() -
seesAvuncularVariables
protected boolean seesAvuncularVariables()Ask whether variables declared in an "uncle" element are visible.- Overrides:
seesAvuncularVariables
in classStyleElement
- Returns:
- false if this xsl:param is a child of xsl:function (new rule in 4.0 draft)
-
fixupReferences
Description copied from class:StyleElement
Fix up references from XPath expressions. Overridden for function declarations and variable declarations- Overrides:
fixupReferences
in classStyleElement
- Throws:
XPathException
- if any references cannot be fixed up.
-
compile
Description copied from class:StyleElement
Compile the instruction on the stylesheet tree into an executable instruction for use at run-time.- Overrides:
compile
in classStyleElement
- Parameters:
exec
- the compilation episodedecl
- the containing top-level declaration, for example xsl:function or xsl:template- 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
- if validation fails
-
getCompiledParam
-
getRequiredType
Get the static type of the parameter. This is the declared type, because we cannot know the actual value in advance.- Returns:
- the declared type (or
item()*
if no type is declared)
-
