Method Detail

getSingleInjectionLocation

public InjectStrategy.InjectLocation getSingleInjectionLocation(ProgramClass targetClass,
                                                                ProgramMethod targetMethod)

Find the first offset of return or throw instructions to inject a method invocation.

Specified by:

getSingleInjectionLocation in interface InjectStrategy

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 the first offset suitable for injection.

Specified by:

getAllSuitableInjectionLocation in interface InjectStrategy

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 one InjectLocation instance indicating the first offset suitable for injection.
