Constructor Detail

ProcessingException

public ProcessingException(String message)

Construct a new ProcessingException instance.

ProcessingException

public ProcessingException(Exception ex)

Creates a new ProcessingException instance.

Parameters:

ex - an Exception value

ProcessingException

public ProcessingException(String message,
                           Throwable t)

Construct a new ProcessingException that references a parent Exception.

ProcessingException

public ProcessingException(String message,
                           Location location)

Construct a new ProcessingException that has an associated location.

ProcessingException

protected ProcessingException(String message,
                              Throwable t,
                              Location location)

Construct a new ProcessingException that has a parent exception and an associated location.

This constructor is protected to enforce the use of throwLocated(String, Throwable, Location) which limits exception nesting as far as possible.

Method Detail

throwLocated

public static ProcessingException throwLocated(String message,
                                               Throwable thr,
                                               Location location)
                                        throws ProcessingException

Throw a located exception given an existing exception and the location where this exception was catched.

If the exception is already a ProcessingException or a LocatedRuntimeException, the location is added to the original exception's location chain and the original exception is rethrown (description is ignored) to limit exception nesting. Otherwise, a new ProcessingException is thrown, wrapping the original exception.

Note: this method returns an exception as a convenience if you want to keep the throw semantics in the caller code, i.e. write
throw ProcessingException.throwLocated(...);
instead of
ProcessingException.throwLocated(...);
return;

Parameters:

message - a message (can be null)

thr - the original exception (can be null)

location - the location (can be null)

Returns:

a (fake) located exception

Throws:

ProcessingException - or LocatedRuntimeException

throwLocated

public static ProcessingException throwLocated(String message,
                                               Throwable thr,
                                               List locations)
                                        throws ProcessingException

Throw a located exception given an existing exception and the locations where this exception was catched.

If the exception is already a ProcessingException or a LocatedRuntimeException, the locations are added to the original exception's location chain and the original exception is rethrown (description is ignored) to limit exception nesting. Otherwise, a new ProcessingException is thrown, wrapping the original exception.

Note: this method returns an exception as a convenience if you want to keep the throw semantics in the caller code, i.e. write
throw ProcessingException.throwLocated(...);
instead of
ProcessingException.throwLocated(...);
return;

Parameters:

message - a message (can be null)

thr - the original exception (can be null)

locations - the locations (can be null)

Returns:

a (fake) located exception

Throws:

ProcessingException - or LocatedRuntimeException
