Method Detail

isJavaIdentifierStart

protected static boolean isJavaIdentifierStart(char c)

Determine whether a character may be the start of a Java identifier.

Parameters:

c - the character

Returns:

true if the character may be the start of a Java identifier, false otherwise

isJavaIdentifierPart

protected static boolean isJavaIdentifierPart(char c)

Determine whether a character may be part of a Java identifier.

Parameters:

c - the character

Returns:

true if the character may be part of a Java identifier, false otherwise

startIndexing

public void startIndexing(IndexingContext context)

Description copied from interface: Indexer

Indexing is about to start on the given context.

Specified by:

startIndexing in interface Indexer

Parameters:

context - the indexing context

endIndexing

public void endIndexing(IndexingContext context)

Description copied from interface: Indexer

Indexing has finished on the given context.

Specified by:

endIndexing in interface Indexer

Parameters:

context - the indexing context

index

public void index(IndexingContext context,
                  DataCollector data)

Description copied from interface: Indexer

Index the current file in the context. The text buffer returned by IndexingContext.getTextBuffer() is read locked at the time this method is called. Note that any Throwable thrown by implementations of this method is considered a bug and will be reported to the user.

Specified by:

index in interface Indexer

Parameters:

context - the context

data - the data collector where the Indexer should store its data

indexImpl

protected void indexImpl(IndexingContext context,
                         DataCollector data,
                         char[] filter,
                         javax.swing.text.Segment segment)

Index the current file in the context, using the given filter.

Parameters:

context - the indexing context

data - the data collector

filter - the filter, or null if no filter

segment - a segment that can be used to store string data

reportKeyword

protected void reportKeyword(DataCollector data,
                             ReadTextBuffer buffer,
                             int start,
                             int end,
                             char[] filter,
                             int hash,
                             int flags,
                             javax.swing.text.Segment segment)

filterKeyword

protected boolean filterKeyword(ReadTextBuffer buffer,
                                int start,
                                int end,
                                char[] filter,
                                javax.swing.text.Segment segment)
