Method Detail

getModule

public IModule getModule()

Specified by:

getModule in interface ITypeLoader

Returns:

The module to which this type loader belongs.

isCaseSensitive

public boolean isCaseSensitive()

Specified by:

isCaseSensitive in interface ITypeLoader

handlesFile

public boolean handlesFile(IFile file)

Specified by:

handlesFile in interface ITypeLoader

handlesDirectory

public boolean handlesDirectory(IDirectory dir)

Specified by:

handlesDirectory in interface ITypeLoader

getNamespaceForDirectory

public String getNamespaceForDirectory(IDirectory dir)

Specified by:

getNamespaceForDirectory in interface ITypeLoader

getTypesForFile

public String[] getTypesForFile(IFile file)

Description copied from interface: ITypeLoader

Returns ALL type names associated with the given file whether or not the types have been loaded yet. Type loading should NOT be used in the implementation of this method.

Specified by:

getTypesForFile in interface ITypeLoader

Parameters:

file - The file in question

Returns:

All known types derived from that file

refreshedFile

public RefreshKind refreshedFile(IFile file,
                                 String[] types,
                                 RefreshKind kind)

Description copied from interface: ITypeLoader

Notifies the type loader that a file has been refreshed. The type loader should return all types that it knows need to be refreshed based on the given file.

Specified by:

refreshedFile in interface ITypeLoader

Parameters:

file - The file that was refreshed

Returns:

All known types affected by the file change

getResource

public URL getResource(String name)

Description copied from interface: ITypeLoader

Finds the resource with the given name. A resource is some data that can be accessed by class code in a way that may be independent of the location of the code. The exact location of the resource is dependent upon the loader implementation

The name of a resource is a '/'-separated path name that identifies the resource.

Specified by:

getResource in interface ITypeLoader

Parameters:

name - The resource name

Returns:

A URL object for reading the resource, or null if the resource could not be found or the invoker doesn't have adequate privileges to get the resource.

refreshedTypes

public final void refreshedTypes(RefreshRequest request)

Description copied from interface: ITypeLoader

Fired when an existing type is refreshed, i.e. there are potential changes

Specified by:

refreshedTypes in interface ITypeLoader

refreshedTypesImpl

protected void refreshedTypesImpl(RefreshRequest request)

refreshed

public final void refreshed()

Description copied from interface: ITypeLoader

Fired when the typesystem is fully refreshed

Specified by:

refreshed in interface ITypeLoader

clearTypeNames

protected void clearTypeNames()

refreshedImpl

protected void refreshedImpl()

toString

public String toString()

Overrides:

toString in class Object

getTypeNames

public Set<TypeName> getTypeNames(String namespace)

Specified by:

getTypeNames in interface ITypeLoader

getTypeNames

public static Set<TypeName> getTypeNames(String parentNamespace,
                                         ITypeLoader loader)

showTypeNamesInIDE

public boolean showTypeNamesInIDE()

Specified by:

showTypeNamesInIDE in interface ITypeLoader

shutdown

public void shutdown()

Specified by:

shutdown in interface ITypeLoader

deleteIndexFile

protected void deleteIndexFile()

saveTypeNames

public void saveTypeNames()

loadTypeNames

public Set<String> loadTypeNames()

getAllTypeNames

public final Set<String> getAllTypeNames()

Specified by:

getAllTypeNames in interface ITypeLoader

Returns:

the set of fully qualified type names this loader is responsible for loading. Note due to the dynamic nature of some type loaders, there is no guarantee that all types for a given loader are known at the time this method is called.

shouldCacheTypeNames

protected boolean shouldCacheTypeNames()
