org.palladiosimulator.commons.stoex.api.impl.generic.GenericXtextToolProviderImpl<T>

Type Parameters:

T - The type of the requested tool.

All Implemented Interfaces:

javax.inject.Provider<T>, GenericXtextToolProvider<T>

Direct Known Subclasses:

PlainXtextStoExParserProvider, PlainXtextStoExSerialiserProvider

public abstract class GenericXtextToolProviderImpl<T>
extends Object
implements GenericXtextToolProvider<T>

Abstract base class for GenericXtextToolProvider implementations. The logic first tries to collect an implementation from an extension point and tries to create an instance from a standalone initialised provider afterwards. The implementation guarantees to return an implementation if the requested tool type can be provided by the Xtext framework.
