Enum Constant Detail

READ_ONLY

public static final Advice.Dispatcher.OffsetMapping.Target.ForNullConstant READ_ONLY

A null constant that can only be put onto the stack.

READ_WRITE

public static final Advice.Dispatcher.OffsetMapping.Target.ForNullConstant READ_WRITE

A null constant that also allows virtual writes where the result is simply popped.

Method Detail

values

public static Advice.Dispatcher.OffsetMapping.Target.ForNullConstant[] 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.Dispatcher.OffsetMapping.Target.ForNullConstant c : Advice.Dispatcher.OffsetMapping.Target.ForNullConstant.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.Dispatcher.OffsetMapping.Target.ForNullConstant 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

resolveAccess

public int resolveAccess(MethodVisitor methodVisitor,
                         int opcode)

Description copied from interface: Advice.Dispatcher.OffsetMapping.Target

Applies this offset mapping for a MethodVisitor.visitVarInsn(int, int) instruction.

Specified by:

resolveAccess in interface Advice.Dispatcher.OffsetMapping.Target

Parameters:

methodVisitor - The method visitor onto which this offset mapping is to be applied.

opcode - The opcode of the original instruction.

Returns:

The required padding to the advice's total stack size.

onWrite

protected abstract void onWrite(MethodVisitor methodVisitor)

Determines the behavior when writing to the target.

Parameters:

methodVisitor - The method visitor to which to write the result of the mapping.

resolveIncrement

public int resolveIncrement(MethodVisitor methodVisitor,
                            int increment)

Description copied from interface: Advice.Dispatcher.OffsetMapping.Target

Applies this offset mapping for a MethodVisitor.visitIincInsn(int, int) instruction.

Specified by:

resolveIncrement in interface Advice.Dispatcher.OffsetMapping.Target

Parameters:

methodVisitor - The method visitor onto which this offset mapping is to be applied.

increment - The value with which to increment the targeted value.

Returns:

The required padding to the advice's total stack size.

toString

public String toString()

Overrides:

toString in class Enum<Advice.Dispatcher.OffsetMapping.Target.ForNullConstant>
