Examples of ResolveContext

org.jboss.gravia.resolver.ResolveContext
A resolve context provides resources, options and constraints to the potential solution of a {@link Resolver#resolve(ResolveContext) resolve}operation.
Resolve Contexts:
- Specify the mandatory and optional resources to resolve. The mandatory and optional resources must be consistent and correct. For example, they must not violate the singleton policy of the implementer.
- Provide {@link Capability capabilities} that the Resolver can use tosatisfy {@link Requirement requirements} via the{@link #findProviders(Requirement)} method
- Constrain solutions via the {@link #getWirings()} method. A wiringconsists of a map of existing {@link Resource resources} to {@link Wiring wiring}.
- Filter requirements that are part of a resolve operation via the {@link #isEffective(Requirement)}.
A resolver may call the methods on the resolve context any number of times during a resolve operation using any thread. Implementors should ensure that this class is properly thread safe.
The resolve context methods must be idempotent. This means that resources must have constant capabilities and requirements and the resolve context must return a consistent set of capabilities, wires and effective requirements. @author thomas.diesler@jboss.com @since 02-Apr-2012
