ErrorCollector (groovy 3.0.1 API)

org.codehaus.groovy.control.ErrorCollector

All Implemented Interfaces and Traits:

Serializable
```
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.

Methods Summary

Methods
Type Params	Return Type	Name and description
	`void`	`addCollectorContents(ErrorCollector that)`
	`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)`
	`void`	`addError(String error, CSTNode context, SourceUnit source)`
	`void`	`addErrorAndContinue(SyntaxException error, SourceUnit source)`
	`void`	`addErrorAndContinue(Message message)` Adds an error to the message set, but does not cause a failure.
	`void`	`addException(Exception exception, SourceUnit source)`
	`void`	`addFatalError(Message message)` Adds an error to the message set and throws CompilationFailedException.
	`void`	`addWarning(WarningMessage message)` Adds a warning to the message set.
	`void`	`addWarning(int importance, String text, CSTNode context, SourceUnit source)` Adds a warning to the message set if it is relevant.
	`void`	`addWarning(int importance, String text, Object data, CSTNode context, SourceUnit source)` Adds a warning to the message set if it is relevant.
	`protected void`	`failIfErrors()` Causes the current phase to fail by throwing a CompilationFailedException.
	`CompilerConfiguration`	`getConfiguration()` Returns: 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<? extends Message>`	`getErrors()` Returns the list of errors, or null if there are none.
	`Exception`	`getException(int index)` Returns the specified error's underlying Exception, or null if it isn't one.
	`Message`	`getLastError()` Returns the last error reported.
	`SyntaxException`	`getSyntaxError(int index)` Returns 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<WarningMessage>`	`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.

    ErrorMessages collected during processing
  - protected LinkedList<WarningMessage> warnings
    
    WarningMessages collected during processing
- Constructor Detail

    Initialize the ErrorReporter.
- Method Detail
  - public void addCollectorContents(ErrorCollector that)
  - 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.
  - 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
  - public void addError(SyntaxException error, SourceUnit source)
  - public void addError(String error, CSTNode context, SourceUnit source)
  - public void addErrorAndContinue(SyntaxException error, SourceUnit source)
  - 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.
  - public void addException(Exception exception, SourceUnit source)
  - public void addFatalError(Message message)
    
    Adds an error to the message set and throws CompilationFailedException.
  - public void addWarning(WarningMessage message)
    
    Adds a warning to the message set.
  - public void addWarning(int importance, String text, CSTNode context, SourceUnit source)
