Method Detail

getSingleInjectionLocation

InjectStrategy.InjectLocation getSingleInjectionLocation(ProgramClass targetClass,
                                                         ProgramMethod targetMethod)

Determine one location (i.e. offset) suitable for injecting a method invocation.

Parameters:

targetClass - The class holding the method in which a method invocation will be injected.

targetMethod - The target method to have a method invocation injected into.

Returns:

An InjectLocation instance indicating an offset suitable for injection and whether the injection shall happen before or after the offset.

getAllSuitableInjectionLocation

InjectStrategy.InjectLocation[] getAllSuitableInjectionLocation(ProgramClass targetClass,
                                                                ProgramMethod targetMethod)

Determine all locations (i.e., offsets) suitable for injecting a method invocation.

Parameters:

targetClass - The class holding the method in which a method invocation will be injected.

targetMethod - The target method to have a method invocation injected into.

Returns:

An array of InjectLocation instances indicating offsets suitable for injection and whether the injection shall take place before or after each offset.
