CheckpointedStreamDefinitionException

public CheckpointedStreamDefinitionException(java.lang.String expressionString,
                                     int textPosition,
                                     int tokenPointer,
                                     int checkpointPointer,
                                     java.util.List<Token> tokens,
                                     XDDSLMessages message,
                                     java.lang.Object... inserts)

Construct a new exception

Parameters:

expressionString - the raw, untokenized text that was being parsed

textPosition - the text offset where the error occurs

checkpointPointer - the token-index of the last known good token

tokenPointer - the token-index of token where the error occured

tokens - the list of tokens that make up expressionString

message - the error message

inserts - variables that may be inserted in the error message

Method Detail

getMessage

public java.lang.String getMessage()

Overrides:

getMessage in class StreamDefinitionException

Returns:

a formatted message with inserts applied.

getCheckpointPosition

public int getCheckpointPosition()

getExpressionStringUntilCheckpoint

public java.lang.String getExpressionStringUntilCheckpoint()

Return the parsed expression until the last known, well formed position. Attempting to re-parse that expression is guaranteed to not fail.

getCheckpointPointer

public int getCheckpointPointer()

getTokens

public java.util.List<Token> getTokens()

getTokenPointer

public int getTokenPointer()
