org.codehaus.groovy.control
[Java] Class ErrorCollector

java.lang.Object
  org.codehaus.groovy.control.ErrorCollector

public class ErrorCollector
extends Object

A base class for collecting messages and errors during processing. Each CompilationUnit should have an ErrorCollector, and the SourceUnits should share their ErrorCollector with the CompilationUnit.

Authors:

Version:

Field Summary
protected CompilerConfiguration configuration

Configuration and other settings that control processing
protected LinkedList errors

ErrorMessages collected during processing
protected LinkedList warnings

WarningMessages collected during processing
 
Constructor Summary
ErrorCollector(CompilerConfiguration configuration)

Initialize the ErrorReporter.
 
Method Summary
void addCollectorContents(ErrorCollector er)

void addError(Message message)

Adds a non-fatal error to the message set, which may cause a failure if the error threshold is exceeded.

void addError(Message message, boolean fatal)

Adds an optionally-fatal error to the message set.

void addError(SyntaxException error, SourceUnit source)

Convenience wrapper for addError().
void addError(String text, CSTNode context, SourceUnit source)

Convenience wrapper for addError().
void addErrorAndContinue(Message message)

Adds an error to the message set, but does not cause a failure.

void addException(Exception cause, SourceUnit source)

void addFatalError(Message message)

Adds a fatal exception to the message set and throws the unit as a PhaseFailedException.
void addWarning(WarningMessage message)

Adds a WarningMessage to the message set.
void addWarning(int importance, String text, CSTNode context, SourceUnit source)

Convenience wrapper for addWarning() that won't create an object unless it is relevant.
void addWarning(int importance, String text, Object data, CSTNode context, SourceUnit source)

Convenience wrapper for addWarning() that won't create an object unless it is relevant.
protected void failIfErrors()

Causes the current phase to fail by throwing a CompilationFailedException.
CompilerConfiguration getConfiguration()

@return the compiler configuration used to create this error collector
Message getError(int index)

Returns the specified error message, or null.
int getErrorCount()

Returns the number of errors.
List getErrors()

Returns the list of errors, or null if there are none.
Exception getException(int index)

Convenience routine to return the specified error's underlying Exception, or null if it isn't one.
Message getLastError()

Returns the last error reported
SyntaxException getSyntaxError(int index)

Convenience routine to return the specified error's underlying SyntaxException, or null if it isn't one.
WarningMessage getWarning(int index)

Returns the specified warning message, or null.
int getWarningCount()

Returns the number of warnings.
List getWarnings()

Returns the list of warnings, or null if there are none.
boolean hasErrors()

Returns true if there are any errors pending.
boolean hasWarnings()

Returns true if there are any warnings pending.
void write(PrintWriter writer, Janitor janitor)

Writes error messages to the specified PrintWriter.

Method Detail

addCollectorContents

public void addCollectorContents(ErrorCollector er)

addError

public void addError(Message message)
Adds a non-fatal error to the message set, which may cause a failure if the error threshold is exceeded. The message is not required to have a source line and column specified, but it is best practice to try and include that information.

addError

public void addError(Message message, boolean fatal)
Adds an optionally-fatal error to the message set. The message is not required to have a source line and column specified, but it is best practice to try and include that information.
Parameters:
fatal - if true then then processing will stop

addError

public void addError(SyntaxException error, SourceUnit source)
Convenience wrapper for addError().

addError

public void addError(String text, CSTNode context, SourceUnit source)
Convenience wrapper for addError().

addErrorAndContinue

public void addErrorAndContinue(Message message)
Adds an error to the message set, but does not cause a failure. The message is not required to have a source line and column specified, but it is best practice to try and include that information.

addException

public void addException(Exception cause, SourceUnit source)

addFatalError

public void addFatalError(Message message)
Adds a fatal exception to the message set and throws the unit as a PhaseFailedException.

addWarning

public void addWarning(WarningMessage message)
Adds a WarningMessage to the message set.

addWarning

public void addWarning(int importance, String text, CSTNode context, SourceUnit source)
Convenience wrapper for addWarning() that won't create an object unless it is relevant.

addWarning

public void addWarning(int importance, String text, Object data, CSTNode context, SourceUnit source)
Convenience wrapper for addWarning() that won't create an object unless it is relevant.

failIfErrors

protected void failIfErrors()
Causes the current phase to fail by throwing a CompilationFailedException.
