Returns true if the first discovered line number information should be prepended to the advice code.

Specified by:

isPrependLineNumber in interface Advice.Dispatcher.Resolved.ForMethodEnter

Returns:

true if the first discovered line number information should be prepended to the advice code.

getNamedTypes

public Map<String,TypeDefinition> getNamedTypes()

Returns the named types declared by this enter advice.

Specified by:

getNamedTypes in interface Advice.Dispatcher.Resolved.ForMethodEnter

Specified by:

getNamedTypes in interface Advice.Dispatcher.Unresolved

getThrowable

public TypeDescription getThrowable()

Returns the type of throwable for which this exit advice is supposed to be invoked.

Specified by:

getThrowable in interface Advice.Dispatcher.Resolved.ForMethodExit

Returns:

The Throwable type for which to invoke this exit advice or a description of NoExceptionHandler if this exit advice does not expect to be invoked upon any throwable.

getArgumentHandlerFactory

Returns a factory for creating an Advice.ArgumentHandler.

Specified by:

getArgumentHandlerFactory in interface Advice.Dispatcher.Resolved.ForMethodExit

Returns:

A factory for creating an Advice.ArgumentHandler.
