Public Methods

Method Description
Consume ( ) : void

* Move the input pointer to the next incoming token. The stream * must become active with LT(1) available. consume() simply * moves the input pointer so that LT(1) points at the next * input symbol. Consume at least one token. *

* Walk past any token not on the channel the parser is listening to. *

DiscardTokenType ( int ttype ) : void
FillBuffer ( ) : void

* Load all tokens from the token source and put in tokens. * This is done upon first LT request because you might want to * set some token type / channel overrides before filling buffer. *

Get ( int i ) : IToken

* Return absolute token i; ignore which channel the tokens are on; * that is, count all tokens not just on-channel tokens. *

Get ( int start, int count ) : List
GetTokens ( ) : IList
GetTokens ( int start, int stop ) : IList
GetTokens ( int start, int stop, BitSet types ) : IList

* Given a start and stop index, return a List of all tokens in * the token type BitSet. Return null if no tokens were found. This * method looks at both on and off channel tokens. *

GetTokens ( int start, int stop, IList types ) : IList
GetTokens ( int start, int stop, int ttype ) : IList
LA ( int i ) : int
LT ( int k ) : IToken

* Get the ith token from the current position 1..n where k=1 is the * first symbol of lookahead. *

SetDiscardOffChannelTokens ( bool discardOffChannelTokens ) : void
SetTokenSource ( ITokenSource tokenSource ) : void

Reset this token stream by setting its token source.

SetTokenTypeChannel ( int ttype, int channel ) : void

* A simple filter mechanism whereby you can tell this token stream * to force all tokens of type ttype to be on channel. For example, * when interpreting, we cannot exec actions so we need to tell * the stream to force all WS and NEWLINE to be a different, ignored * channel. *
