Field Detail

buffer

private final ParsingController.IndexedTokenBuffer buffer

Maintains a link to the token buffer that is applicable for this output stream.

localEOFReached

private boolean localEOFReached

Indicates whether an end-of-file token has been processed on the attached input stream.

ParsingController.FilteredTokenStream

private ParsingController.FilteredTokenStream(ParsingController.IndexedTokenBuffer buffer)

Creates a new token stream reading from the given buffer. If the buffer is blocked then reading more than the number of tokens in the buffer will yield an end-of-file token.

nextToken

public antlr.Token nextToken()
                      throws antlr.TokenStreamException

Returns the next token from the appropriate lexer.
