Method Detail

init

public void init(RuntimeServices rs)

Description copied from interface: LogSystem

init()

Specified by:

init in interface LogSystem

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 java.lang.Exception

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

Throws:

java.lang.Exception

referenceInsert

public java.lang.Object referenceInsert(java.lang.String reference,
                               java.lang.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(java.lang.String lhs,
                         java.lang.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 java.lang.Object methodException(java.lang.Class claz,
                               java.lang.String method,
                               java.lang.Exception e)
                                 throws java.lang.Exception

Handles exceptions thrown during in-template method access

Specified by:

methodException in interface MethodExceptionEventHandler

Throws:

java.lang.Exception

logVelocityMessage

public void logVelocityMessage(int level,
                      java.lang.String message)

handler for LogSystem interface

Specified by:

logVelocityMessage in interface LogSystem
