Method Detail

resolveOrphanComponents

public static Set<ComponentAst> resolveOrphanComponents(ArtifactAst appModel)

Given an ArtifactAst, return all those components within it that are not accessible from a top-level component.

Parameters:

appModel - the model to determine orphan components from.

Returns:

components within the provided appModel that are not accessible from a top-level component.

emptyArtifact

public static ArtifactAst emptyArtifact()

Provides a singleton empty ArtifactAst instance.

Returns:

an ArtifactAst without components.

parameterOfType

public static Optional<ComponentParameterAst> parameterOfType(ComponentAst referent,
                                                              org.mule.runtime.api.meta.model.stereotype.StereotypeModel referenceStereotype)

Given a ComponentAst, lookup for a parameter that references an object with a certain stereotype.

Parameters:

referent - the ComponentAst that will be checked for the reference.

referenceStereotype - the StereotypeModel to check for.

Returns:

a ComponentParameterAst representing a parameter of referent that references an object assignable to referenceStereotype, if it exists.
