EventHandlingTestCase

public EventHandlingTestCase()

Default constructor.

Method Detail

init

public void init(RuntimeServices rs)

suite

public static junit.framework.Test suite()

runTest

public void runTest()

Runs the test.

Overrides:

runTest in class junit.framework.TestCase

throwException

public void throwException()
                    throws Exception

silly method to throw an exception to test the method invocation exception event handling

Throws:

Exception

referenceInsert

public Object referenceInsert(String reference,
                              Object value)

Event handler for when a reference is inserted into the output stream.

Specified by:

referenceInsert in interface ReferenceInsertionEventHandler

Parameters:

reference - Reference from template about to be inserted.

value - Value about to be inserted (after its toString() method is called).

Returns:

Object on which toString() should be called for output.

shouldLogOnNullSet

public boolean shouldLogOnNullSet(String lhs,
                                  String rhs)

Event handler for when the right hand side of a #set() directive is null, which results in a log message. This method gives the application a chance to 'vote' on msg generation

Specified by:

shouldLogOnNullSet in interface NullSetEventHandler

Parameters:

lhs - reference literal of left-hand-side of set statement

rhs - reference literal of right-hand-side of set statement

Returns:

true if log message should be written, false otherwise

methodException

public Object methodException(Class claz,
                              String method,
                              Exception e)
                       throws Exception

Handles exceptions thrown during in-template method access

Specified by:

methodException in interface MethodExceptionEventHandler

Throws:

Exception

logVelocityMessage

public void logVelocityMessage(int level,
                               String message)

handler for LogSystem interface
