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

All Implemented Interfaces:

Serializable
```
public class ErrorCollector
extends Object
implements Serializable
```
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.

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`addCollectorContents(ErrorCollector er)`
`void`	`addError(String text, CSTNode context, SourceUnit source)`	Convenience wrapper for addError().
`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(SyntaxException error, SourceUnit source)`	Convenience wrapper for addError().
`void`	`addErrorAndContinue(Message message)`	Adds an error to the message set, but does not cause a failure.
`void`	`addErrorAndContinue(SyntaxException error, SourceUnit source)`
`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(int importance, String text, Object data, CSTNode context, SourceUnit source)`	Convenience wrapper for addWarning() that won't create an object unless it is relevant.
`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(WarningMessage message)`	Adds a WarningMessage to the message set.

public void addErrorAndContinue(SyntaxException error,
                                SourceUnit source)
                         throws CompilationFailedException
```
    Throws:
    
    CompilationFailedException
  - 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.
  - addError
```
public void addError(Message message)
              throws CompilationFailedException
```
    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.
    
    Throws:
    
    CompilationFailedException
  - addError
```
public void addError(Message message,
                     boolean fatal)
              throws CompilationFailedException
```
    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
