getBinding

public static Binding getBinding(Map<String,Object> context,
 String expression)

Returns a Binding instance initialized with the variables contained in context. If context is null, an empty Binding is returned.

The expression is parsed to initiate non existing variable in Binding to null for GroovyShell evaluation.

The context Map is added to the Binding as a variable called "context" so that variables can be passed back to the caller. Any variables that are created in the script are lost when the script ends unless they are copied to the "context" Map.

Parameters:

context - A Map containing initial variables

Returns:

A Binding instance
