Method Detail

isModifiableClass

boolean isModifiableClass(java.lang.instrument.Instrumentation instrumentation,
                          java.lang.Class<?> type)

Invokes the Instrumentation#isModifiableClass method.

Parameters:

instrumentation - The instrumentation instance to invoke the method on.

type - The type to consider for modifiability.

Returns:

true if the supplied type can be modified.

isRetransformClassesSupported

boolean isRetransformClassesSupported(java.lang.instrument.Instrumentation instrumentation)

Invokes the Instrumentation#isRetransformClassesSupported method.

Parameters:

instrumentation - The instrumentation instance to invoke the method on.

Returns:

true if the supplied instrumentation instance supports retransformation.

addTransformer

void addTransformer(java.lang.instrument.Instrumentation instrumentation,
                    java.lang.instrument.ClassFileTransformer classFileTransformer,
                    boolean canRetransform)

Registers a transformer.

Parameters:

instrumentation - The instrumentation instance to invoke the method on.

classFileTransformer - The class file transformer to register.

canRetransform - true if the class file transformer should be invoked upon a retransformation.

retransformClasses

void retransformClasses(java.lang.instrument.Instrumentation instrumentation,
                        java.lang.Class<?>[] type)
                 throws java.lang.instrument.UnmodifiableClassException

Retransforms the supplied classes.

Parameters:

instrumentation - The instrumentation instance to invoke the method on.

type - The types to retransform.

Throws:

java.lang.instrument.UnmodifiableClassException - If any of the supplied types are unmodifiable.
