                                                   org.antlr.runtime.BitSet follow)
                                            throws org.antlr.runtime.RecognitionException

Returns:

null if the caller should handle the mismatch

Throws:

errorExpr

public expr errorExpr(PythonTree t)

errorMod

public mod errorMod(PythonTree t)

errorSlice

public slice errorSlice(PythonTree t)

errorStmt

public stmt errorStmt(PythonTree t)

error

public void error(java.lang.String message,
                  PythonTree t)

Handle (normally throw a ParseException) possibly recoverable by waiting for further input.

Parameters:

message - text to include.

t - not null, root of the PythonTree provoking the error.

error

public void error(java.lang.String message,
                  PythonTree t,
                  boolean definite)

Handle (normally throw a ParseException) specifying whether to treat as a final decision. In the REPL, when definite=true, Jython will signal a definite syntax or semantic error, not recoverable by waiting for further input.

Parameters:

message - text to include.

t - not null, root of the PythonTree provoking the error.

definite - true if we cannot recover with more input.
