public interface ReferenceProvider

Provides Reference instances. A ReferenceProvider can be registered through the extension manifest, or using DependencyManager.addReferenceProvider(oracle.ide.dependency.ReferenceProvider).

Method Summary

Modifier and Type	Method and Description
boolean	canFindReferences(Context context, Scope scope, Declaration declaration) Determine whether this provider can find references to a declaration.
boolean	canGetReference(Context context) Determine whether there could be a reference in the context.
boolean	canGetReferences(Context context, Node node) Determine whether this provider can get references for a Node.
java.util.Collection<? extends Reference>	findReferences(Context context, Scope scope, Declaration declaration, ProgressIndicator progress) Find all references to the given declaration that this provider knows about.
Reference	getReference(Context context) Get the reference for the given context, or null if there is no reference in this context.
java.util.Collection<? extends Reference>	getReferences(Context context, Node node) Get all references for a Node.

Method Detail

canGetReference

boolean canGetReference(Context context)

Determine whether there could be a reference in the context. The implementation of this method should be very fast, as it is called from the event thread to enable or disable dependency-related actions.

Parameters:

context - the context

Returns:

true if this provider may have a reference in the context, false otherwise

getReference

Reference getReference(Context context)

Get the reference for the given context, or null if there is no reference in this context. This will only be called if canGetReference(oracle.ide.Context) returned true for this context.

Parameters:

context - the context

Returns:

the reference

canGetReferences

boolean canGetReferences(Context context,
                         Node node)

Determine whether this provider can get references for a Node.

Parameters:

context - the context

node - the Node

Returns:

true if the provider can get references for this Node, false otherwise

getReferences

java.util.Collection<? extends Reference> getReferences(Context context,
                                                        Node node)
                                                 throws java.lang.InterruptedException

Get all references for a Node.

Parameters:

context - the context

node - the Node

Returns:

the references

Throws:

java.lang.InterruptedException - if the operation is interrupted

canFindReferences

boolean canFindReferences(Context context,
                          Scope scope,
                          Declaration declaration)

Determine whether this provider can find references to a declaration. The implementation of this method should be very fast, as it is called from the event thread to enable or disable dependency-related actions.

Parameters:

context - the context

declaration - the declaration

Returns:

true if this provider can find references to the declaration, false otherwise

findReferences

java.util.Collection<? extends Reference> findReferences(Context context,
                                                         Scope scope,
                                                         Declaration declaration,
                                                         ProgressIndicator progress)
                                                  throws java.lang.InterruptedException

Find all references to the given declaration that this provider knows about. This will only be called if canFindReferences(Context, Scope, Declaration) returns true for this context and declaration.

Parameters:

context - the context

declaration - the declaration to search for

progress - the progress indicator

Returns:

the references to the declaration

Throws:

java.lang.InterruptedException - if the operation is interrupted
