BindingReference

All Known Implementing Classes:

Assign, GlobalVariableReference, 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

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`fixup(Binding binding)`	Fix up this binding reference to a binding
`void`	`setStaticType(SequenceType type, GroundedValue 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,
                   GroundedValue 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
