Method Details

resolve

public V resolve(String name)

Description copied from interface: VariableResolver

Receives a variable name and obtains the value associated with the name.

This can be implemented simply on top of a Map (see VariableResolver.ByMap), or this can be used like an expression evaluator.

Specified by:

resolve in interface VariableResolver<V>

Parameters:

name - Name of the variable to be resolved. Never null, never empty. The name shouldn't include the syntactic marker of an expression. IOW, it should be "foo" but not "${foo}". A part of the goal of this design is to abstract away the expression marker syntax.

Returns:

Object referenced by the name. Null if not found.
