Method Summary

Modifier and Type	Method	Description
@Nullable BundledRenderUnit	findUnit(@NotNull org.osgi.framework.BundleContext context, @NotNull Set<TypeProvider> inheritanceChain, @NotNull Set<TypeProvider> allRelatedProviders)	Retrieves the best matching BundledRenderUnit for the provided inheritanceChain, by scanning all TypeProvider bundles for the class or script capable of providing a rendering for resource type chain.

Method Details

findUnit

@Nullable
@Nullable BundledRenderUnit findUnit(@NotNull
 @NotNull org.osgi.framework.BundleContext context,
 @NotNull
 @NotNull Set<TypeProvider> inheritanceChain,
 @NotNull
 @NotNull Set<TypeProvider> allRelatedProviders)

Retrieves the best matching BundledRenderUnit for the provided inheritanceChain, by scanning all TypeProvider bundles for the class or script capable of providing a rendering for resource type chain.

Parameters:

context - the bundle context to use.

inheritanceChain - the resource type chain; the set is ordered from the most specific resource type to the most generic one

allRelatedProviders - this is a super set, containing both the inheritanceChain but also all the required providers; a required provider is a provider that's needed by a ResourceType in order to delegate rendering to it, but it's not extended by the same ResourceType

Returns:

a BundledRenderUnit if one was found, null otherwise

findUnit

@Nullable
@Nullable BundledRenderUnit findUnit(@NotNull
 @NotNull org.osgi.framework.BundleContext context,
 @NotNull
 @NotNull TypeProvider provider,
 @NotNull
 @NotNull Set<TypeProvider> allRelatedProviders)

Retrieves a path-based BundledRenderUnit from the passed provider.

Parameters:

context - the bundle context to use.

provider - the provider from which to retrieve the unit

allRelatedProviders - this is a super set, containing both the providers connected through an inheritance relationship but also all the required providers; a required provider is a provider that's needed by a ResourceType in order to delegate rendering to it, but it's not extended by the same ResourceType

Returns:

a BundledRenderUnit if one was found, null otherwise
