Binding is a interface used to represent the run-time properties and methods
associated with a variable: specifically, a method to get the value
of the variable.
getLocalSlotNumber
public int getLocalSlotNumber()
If this is a local variable held on the local stack frame, return the corresponding slot number.
In other cases, return -1.
- the slot number on the local stack frame
getRequiredType
public SequenceType getRequiredType()
Get the declared type of the variable
getVariableQName
public StructuredQName getVariableQName()
Get the name of the variable
- the name of the variable, as a structured QName
isAssignable
public boolean isAssignable()
Test whether it is permitted to assign to the variable using the saxon:assign
extension element. This will only be for an XSLT global variable where the extra
attribute saxon:assignable="yes" is present.
- true if the binding is assignable
isGlobal
public boolean isGlobal()
Indicate whether the binding is local or global. A global binding is one that has a fixed
value for the life of a query or transformation; any other binding is local.
- true if the binding is global
