直接已知子类:

AccumulatedCodeInjector

public class CodeInjector
extends Object

This utility class allows for injecting a method invocation instruction, optionally with arguments modeled by instances of classes implementing the InjectedArgument interface, to the specified target method at an offset determined by the implementation of the InjectStrategy interface.

Example usage: new CodeInjector() .injectInvokeStatic(logUtilClass, logDebugMethod, new ConstantPrimitive(1), new ConstantString("Hello world")) .into(MainProgramClass, mainMethod) .at(new FirstBlock()) .commit();

方法详细资料

injectInvokeStatic

public CodeInjector injectInvokeStatic(Clazz clazz,
 Method method)

Specify the static method to be invoked.

参数:

clazz - The class containing the static method to be invoked.

method - The method to be invoked.

injectInvokeStatic

public CodeInjector injectInvokeStatic(Clazz clazz,
 Method method,
 InjectedArgument... arguments)

Specify the static method to be invoked.

参数:

clazz - The class containing the static method to be invoked.

method - The method to be invoked.

arguments - A list of arguments to be passed to the method to be invoked.

reset

public void reset()

Resets the internal state of this injector, allowing it to be reused.

This avoids the performance overhead of re-instantiating the attribute editor for subsequent operations.

into

public CodeInjector into(ProgramClass programClass,
 ProgramMethod programMethod)

Specify the method where a static method invocation will be injected into.

参数:

programClass - The program class that has the method where a static method invocation will be injected into.

programMethod - The method where a static method invocation will be injected into.

at

public CodeInjector at(InjectStrategy injectStrategy)

Specify the location in which the invoke instruction should be injected into.

参数:

injectStrategy - The implementation of the InjectStrategy interface which determines the offset to inject the invoke instruction.

store

public LocalVariable store()

commit

public void commit()

Apply the invoke instruction in accordance to the specifications provided via the `.injectInvokeStatic(...)`, `.into(...)` and `.at(...)` methods.

readyToCommit

public boolean readyToCommit()

getTargets

public List<CodeInjector.ClassMethodPair> getTargets()

getContent

public CodeInjector.ClassMethodPair getContent()

getInjectStrategy

public InjectStrategy getInjectStrategy()

getArguments

public List<InjectedArgument> getArguments()

getResultLocalIndex

protected LocalVariable getResultLocalIndex()
