XSLParam

public XSLParam()

Method Detail

allowsValue

protected boolean allowsValue()

Overrides:

allowsValue in class XSLGeneralVariable

allowsRequired

protected boolean allowsRequired()

Overrides:

allowsRequired in class XSLGeneralVariable

allowsTunnelAttribute

protected boolean allowsTunnelAttribute()

Overrides:

allowsTunnelAttribute in class XSLGeneralVariable

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 class XSLVariableDeclaration

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 class StyleElement

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 class XSLVariableDeclaration
