public static final Advice.StackMapFrameHandler.NoOp INSTANCE

The singleton instance.

Method Detail

values

public static Advice.StackMapFrameHandler.NoOp[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Advice.StackMapFrameHandler.NoOp c : Advice.StackMapFrameHandler.NoOp.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Advice.StackMapFrameHandler.NoOp valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

bindEnter

public Advice.StackMapFrameHandler.ForAdvice bindEnter(MethodDescription.InDefinedShape adviceMethod)

Binds this meta data handler for the enter advice.

Specified by:

bindEnter in interface Advice.StackMapFrameHandler.ForInstrumentedMethod

Parameters:

adviceMethod - The enter advice method.

Returns:

An appropriate meta data handler for the enter method.

bindExit

public Advice.StackMapFrameHandler.ForAdvice bindExit(MethodDescription.InDefinedShape adviceMethod)

Binds this meta data handler for the exit advice.

Specified by:

bindExit in interface Advice.StackMapFrameHandler.ForInstrumentedMethod

Parameters:

adviceMethod - The exit advice method.

Returns:

An appropriate meta data handler for the enter method.

getReaderHint

public int getReaderHint()

Returns a hint to supply to a ClassReader when parsing an advice method.

Specified by:

getReaderHint in interface Advice.StackMapFrameHandler.ForInstrumentedMethod

Returns:

The reader hint to supply to an ASM class reader.

translateFrame

public void translateFrame(MethodVisitor methodVisitor,
                           int type,
                           int localVariableLength,
                           @MaybeNull
                           Object[] localVariable,
                           int stackSize,
                           @MaybeNull
                           Object[] stack)
