Interface ComponentInvocation

All Known Implementing Classes:

ApplyTemplates, CallTemplate, GlobalVariableReference, UseAttributeSet, UserFunctionCall, UserFunctionReference

public interface ComponentInvocation

Represents an expression or instruction such as call-template, or a user function call, or a global variable reference, that needs to be bound to a target component, and can potentially be re-bound when the containing component is copied into another package.

Method Summary

Modifier and Type	Method and Description
int	getBindingSlot() Get the binding slot to be used.
Component	getFixedTarget() Get the target component if this is known in advance, that is, if the target component is private or final, or in some other cases such as xsl:original.
SymbolicName	getSymbolicName() Get the symbolic name of the component that this invocation references
void	setBindingSlot(int slot) Set the binding slot to be used.

Method Detail

getFixedTarget

Component getFixedTarget()

Get the target component if this is known in advance, that is, if the target component is private or final, or in some other cases such as xsl:original. Otherwise, return null.

Returns:

the bound component if the binding has been fixed

setBindingSlot

void setBindingSlot(int slot)

Set the binding slot to be used. This is the offset within the binding vector of the containing component where the actual target component is to be found. The target template is not held directly in the invocation instruction/expression itself because it can be overridden in a using package.

Parameters:

slot - the offset in the binding vector of the containing package where the target component can be found.

getBindingSlot

int getBindingSlot()

Get the binding slot to be used. This is the offset within the binding vector of the containing component where the actual target component is to be found.

Returns:

the offset in the binding vector of the containing package where the target component can be found.

getSymbolicName

SymbolicName getSymbolicName()

Get the symbolic name of the component that this invocation references

Returns:

the symbolic name of the target component, or null if there is no component referenced
