<init>

MethodInterceptor implementation that allows for highly customizable method-level tracing, using placeholders.

Trace messages are written on method entry, and if the method invocation succeeds on method exit. If an invocation results in an exception, then an exception message is written. The contents of these trace messages is fully customizable and special placeholders are available to allow you to include runtime information in your log messages. The placeholders available are:

• $[methodName] - replaced with the name of the method being invoked
• $[targetClassName] - replaced with the name of the class that is the target of the invocation
• $[targetClassShortName] - replaced with the short name of the class that is the target of the invocation
• $[returnValue] - replaced with the value returned by the invocation
• $[argumentTypes] - replaced with a comma-separated list of the short class names of the method arguments
• $[arguments] - replaced with a comma-separated list of the String representation of the method arguments
• $[exception] - replaced with the String representation of any Throwable raised during the invocation
• $[invocationTime] - replaced with the time, in milliseconds, taken by the method invocation

There are restrictions on which placeholders can be used in which messages: see the individual message properties for details on the valid placeholders.
