canGetDeclaration

public boolean canGetDeclaration(Context context)

Description copied from interface: DeclarationProvider

Determine whether there could be a declaration 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:

canGetDeclaration in interface DeclarationProvider

Parameters:

context - the context

Returns:

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

getDeclaration

public Declaration getDeclaration(Context context)

Description copied from interface: DeclarationProvider

Get the declaration for the given context. This will only be called if DeclarationProvider.canGetDeclaration(oracle.ide.Context) returned true for this context.

Specified by:

getDeclaration in interface DeclarationProvider

Parameters:

context - the context

Returns:

the declaration

canGetDeclarations

public boolean canGetDeclarations(Context context,
                                  Node node)

Description copied from interface: DeclarationProvider

Determine whether this provider can get declarations for a Node.

Specified by:

canGetDeclarations in interface DeclarationProvider

Parameters:

context - the context

node - the Node

Returns:

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

getDeclarations

public java.util.Collection<Declaration> getDeclarations(Context context,
                                                         Node node)

Description copied from interface: DeclarationProvider

Get all declarations for a Node.

Specified by:

getDeclarations in interface DeclarationProvider

Parameters:

context - the context

node - the Node

Returns:

the declarations

getTopLevelDeclarations

public java.util.Collection<Declaration> getTopLevelDeclarations(Context context,
                                                                 Node node)

Description copied from interface: DeclarationProvider

Get all top-level declarations for a Node.

Some languages have a hierarchy of declarations. Objects further down in the hierarchy can only be accessed through these top-level declarations. For example, methods in a Java class can only be referenced directly through a reference to the Java class. Or columns in a database table might only be referenced through a reference to the table. In those cases, it is possible to search for all references to a Node by searching only for the top-level declarations. This improves performance compared to searching for every declaration in the Node. Implementations that do not have such a declaration hierarchy can simply call DeclarationProvider.getDeclarations(Context,Node).

Specified by:

getTopLevelDeclarations in interface DeclarationProvider

Parameters:

context - the context

node - the Node

Returns:

the top-level declarations

canGetDeclaration

public boolean canGetDeclaration(Context context,
                                 java.lang.String id)

Description copied from interface: IdDeclarationProvider

Determine whether this provider can supply the declaration for an ID. Implementations should return true if they are responsible for this ID, regardless of whether the declaration actually exists.

Specified by:

canGetDeclaration in interface IdDeclarationProvider

Parameters:

context - the context

id - the declaration ID

Returns:

true if the provider can find the declaration

getDeclaration

public IdDeclaration getDeclaration(Context context,
                                    java.lang.String id)
                             throws java.lang.InterruptedException

Description copied from interface: IdDeclarationProvider

Get the declaration corresponding to an ID.

Specified by:

getDeclaration in interface IdDeclarationProvider

Parameters:

context - the context

id - the declaration ID

Returns:

the declaration, or null if the declaration is not found

Throws:

java.lang.InterruptedException - if the operation is interrupted
