Interface BindingReference

All Known Implementing Classes:

Assign, LocalVariableReference, VariableReference

public interface BindingReference

BindingReference is a interface used to mark references to a variable declaration. The main implementation is VariableReference, which represents a reference to a variable in an XPath expression, but it is also used to represent a reference to a variable in a saxon:assign instruction.

Method Summary

void	fixup(Binding binding) Fix up this binding reference to a binding
void	setStaticType(SequenceType type, Value constantValue, int properties) Fix up the static type of this variable reference; optionally, supply a constant value for the variable.

Method Detail

setStaticType

void setStaticType(SequenceType type,
                   Value constantValue,
                   int properties)

Fix up the static type of this variable reference; optionally, supply a constant value for the variable. Also supplies other static properties of the expression to which the variable is bound, for example whether it is an ordered node-set.

Parameters:

type - The static type of the variable reference, typically either the declared type of the variable, or the static type of the expression to which the variable is bound

constantValue - if non-null, indicates that the value of the variable is known at compile time, and supplies the value

properties - static properties of the expression to which the variable is bound

fixup

void fixup(Binding binding)

Fix up this binding reference to a binding

Parameters:

binding - the Binding to which the variable refers
