Constructor Detail

RepairingTokenBuffer

public RepairingTokenBuffer(ASToken[] tokens)

Constructor

Parameters:

tokens - list of ASTokens (or any subclass of antlr.Token)

Method Detail

insertSemicolon

public final boolean insertSemicolon(boolean isNextToken)

Description copied from interface: IRepairingTokenBuffer

Inserts a semicolon into the token stream

Specified by:

insertSemicolon in interface IRepairingTokenBuffer

Parameters:

isNextToken - true if the semicolon should be the next token

Returns:

true if the semicolon was successfully inserted.

rewind

public final void rewind(int position)

Description copied from interface: IRepairingTokenBuffer

Rewinds the token buffer to the given position. This is optional

Specified by:

rewind in interface IRepairingTokenBuffer

Parameters:

position - the non-negative position

consume

public final void consume()

Description copied from interface: IRepairingTokenBuffer

Consumes the current token in the buffer

Specified by:

consume in interface IRepairingTokenBuffer

lookAheadSkipInsertedSemicolon

protected final ASToken lookAheadSkipInsertedSemicolon(int i)

Description copied from class: BaseRepairingTokenBuffer

Look-ahead "i" tokens and ignore BaseRepairingTokenBuffer.insertSemis flag. Subclasses provide implementations specific to how they access the token buffer.

getTokens

public IASToken[] getTokens(boolean includeInserted)

Get all the tokens in this buffer.

Parameters:

includeInserted - True if automatically inserted semicolons are included in the result.

Returns:

All the tokens in the buffer.

previous

public ASToken previous()

Description copied from interface: IRepairingTokenBuffer

Returns the previous token the buffer was looking at

Specified by:

previous in interface IRepairingTokenBuffer

Returns:

the previous token, or EOF

matchOptionalSemicolon

public boolean matchOptionalSemicolon()

If we don't have the optional semicolon, always insert it. This implementation is much looser than StreamingTokenBuffer.matchOptionalSemicolon() in order to appease code model.

Specified by:

matchOptionalSemicolon in interface IRepairingTokenBuffer

Returns:

Always true.
