Examples of org.osgi.service.resolver.Resolver.resolve()

org.osgi.service.resolver.Resolver.resolve()
Resolve the specified resolve context and return any new resources and wires to the caller.
The resolver considers two groups of resources:
- Mandatory - any resource in the {@link ResolveContext#getMandatoryResources() mandatory group} must beresolved. A failure to satisfy any mandatory requirement for these resources will result in throwing a {@link ResolutionException}
- Optional - any resource in the {@link ResolveContext#getOptionalResources() optional group} may beresolved. A failure to satisfy a mandatory requirement for a resource in this group will not fail the overall resolution but no resources or wires will be returned for that resource.
The resolve method returns the delta between the start state defined by {@link ResolveContext#getWirings()} and the end resolved state. That is,only new resources and wires are included.
The behavior of the resolver is not defined if the specified resolve context supplies inconsistent information. @param context The resolve context for the resolve operation. Must not be{@code null}. @return The new resources and wires required to satisfy the specifiedresolve context. The returned map is the property of the caller and can be modified by the caller. @throws ResolutionException If the resolution cannot be satisfied.
