LegacyCommonTokenStream Methods

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.

Determines whether the specified object is equal to the current object.

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.

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

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

Serves as the default hash function.

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.

Gets the Type of the current instance.

Look backwards k tokens on-channel tokens

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

Creates a shallow copy of the current Object.

Reset this token stream by setting its token source.

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.

Given a starting index, return the index of the first on-channel token.
