Class Resolver

java.lang.Object

com.google.api.tools.framework.processors.resolver.Resolver

All Implemented Interfaces:

Processor

public class Resolver
extends java.lang.Object
implements Processor

A processor which establishes the Resolved stage.

The resolver does a proper context check on the model constructed from a protocol descriptor. There is not assumption that the protocol compiler would have run before us, allowing tools building the model from descriptors which are inconsistent, and getting proper error messages instead of crashes.

Method Detail

requires

public com.google.common.collect.ImmutableList<com.google.inject.Key<?>> requires()

Description copied from interface: Processor

The list of stages this processor needs for its operations. Stages are attached as attributes on the Model. A stage may or may not be associated with actual data of the type of the parameter of the key.

Specified by:

requires in interface Processor

establishes

public com.google.inject.Key<?> establishes()

Description copied from interface: Processor

The stage this processor establishes if operation successfully finishes. The processor is responsible to attach the stage key to the model.

Specified by:

establishes in interface Processor

run

public boolean run(Model model)

Description copied from interface: Processor

Runs this processor. It is guaranteed that the Processor.requires() stages are established before this method is called via Model.establishStage(Key). The method should return true if processing successfully finished and the given Processor.establishes() key has been attached to the model. Any errors, warnings, and hints during processing should be attached to the model via Model.getDiagCollector().
