Method Detail

resolve

public Object resolve(Object contextObject,
                      String name,
                      ResolutionContext context)

Description copied from interface: Resolver

Resolve the value from specified context object and name. This method should return as fast as possible. The best practice is to verify params first and return null in case of the resolver is not capable of resolving it. ResolutionContext allows to register a callback to release all the relevant resources after the resolved value is used.

Parameters:

contextObject - The current context object (aka base object), may be null

name - The name (the key or its part) is never null

context - The current resolution context

Returns:

the resolved object or null
