Method Detail

getReferenceCriteria

protected abstract java.util.Collection<QueryCriteria> getReferenceCriteria(Context context,
                                                                            Declaration declaration)

Get the index query criteria to use to search for references to a declaration.

Parameters:

context - the context

declaration - the declaration

Returns:

the query critiera

getContentSet

protected ContentSet getContentSet(Context context,
                                   Project project,
                                   Declaration declaration)

Get the content set that should be searched for references to a declaration.

Parameters:

context - the context

project - the project being searched

declaration - the declaration

Returns:

the content set to search, or null to search the entire project

canGetReference

public boolean canGetReference(Context context)

Description copied from interface: ReferenceProvider

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.

Specified by:

canGetReference in interface ReferenceProvider

Parameters:

context - the context

Returns:

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

getReference

public Reference getReference(Context context)

Description copied from interface: ReferenceProvider

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

Specified by:

getReference in interface ReferenceProvider

Parameters:

context - the context

Returns:

the reference

canGetReferences

public boolean canGetReferences(Context context,
                                Node node)

Description copied from interface: ReferenceProvider

Determine whether this provider can get references for a Node.

Specified by:

canGetReferences in interface ReferenceProvider

Parameters:

context - the context

node - the Node

Returns:

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

getReferences

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

Description copied from interface: ReferenceProvider

Get all references for a Node.

Specified by:

getReferences in interface ReferenceProvider

Parameters:

context - the context

node - the Node

Returns:

the references

Throws:

java.lang.InterruptedException - if the operation is interrupted

canFindReferences

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

Description copied from interface: ReferenceProvider

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.

Specified by:

canFindReferences in interface ReferenceProvider

Parameters:

context - the context

declaration - the declaration

Returns:

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

findReferences

public java.util.Collection<? extends Reference> findReferences(Context context,
                                                                Scope scope,

Specified by:

findReferences in interface ReferenceProvider

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

verify

                         IndexReference reference,
                         Declaration declaration)
                  throws java.lang.InterruptedException

Verify that a reference points to a declaration.

Parameters:
