Constructor Detail

FileTypeIndexImpl

public FileTypeIndexImpl()

Method Detail

getName

public ID<FileType,java.lang.Void> getName()

Specified by:

getName in class FileBasedIndexExtension<FileType,java.lang.Void>

getIndexer

public DataIndexer<FileType,java.lang.Void,FileContent> getIndexer()

Specified by:

getIndexer in class IndexExtension<FileType,java.lang.Void,FileContent>

getKeyDescriptor

public KeyDescriptor<FileType> getKeyDescriptor()

Specified by:

getKeyDescriptor in class IndexExtension<FileType,java.lang.Void,FileContent>

getInputFilter

public FileBasedIndex.InputFilter getInputFilter()

Specified by:

getInputFilter in class FileBasedIndexExtension<FileType,java.lang.Void>

Returns:

filter for file are supposed being indexed by the IndexExtension.getIndexer(). Usually DefaultFileTypeSpecificInputFilter can be used here to index only files with given file-type. Note that check only file's extension is usually error-prone way and prefer to check VirtualFile.getFileType(): for example user can enforce language file as plain text one.

dependsOnFileContent

public boolean dependsOnFileContent()

Specified by:

dependsOnFileContent in class FileBasedIndexExtension<FileType,java.lang.Void>

getVersion

public int getVersion()

Specified by:

getVersion in class IndexExtension<FileType,java.lang.Void,FileContent>

createIndexImplementation

public UpdatableIndex<FileType,java.lang.Void,FileContent> createIndexImplementation(FileBasedIndexExtension<FileType,java.lang.Void> extension,
                                                                                     IndexStorage<FileType,java.lang.Void> storage)
                                                                              throws StorageException,
