Enum Constant Detail

GENERATE

public static final Implementation.Context.FrameGeneration GENERATE

Indicates that frames should be generated.

EXPAND

public static final Implementation.Context.FrameGeneration EXPAND

Indicates that frames should be generated and expanded.

DISABLED

public static final Implementation.Context.FrameGeneration DISABLED

Method Detail

values

public static Implementation.Context.FrameGeneration[] 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 (Implementation.Context.FrameGeneration c : Implementation.Context.FrameGeneration.values())
    System.out.println(c);

Returns:

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

valueOf

public static Implementation.Context.FrameGeneration 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

isActive

public boolean isActive()

Returns true if frames should be generated.

Returns:

true if frames should be generated.

same

public void same(MethodVisitor methodVisitor,
                 List<? extends TypeDefinition> localVariables)

Inserts a Opcodes.F_SAME frame.

Parameters:

methodVisitor - The method visitor to write to.

localVariables - The local variables that are defined at this frame location.

same1

public void same1(MethodVisitor methodVisitor,
                  TypeDefinition stackValue,
                  List<? extends TypeDefinition> localVariables)

Inserts a Opcodes.F_SAME1 frame.

Parameters:

methodVisitor - The method visitor to write to.

stackValue - The single stack value.

localVariables - The local variables that are defined at this frame location.

append

public void append(MethodVisitor methodVisitor,
                   List<? extends TypeDefinition> appended,
                   List<? extends TypeDefinition> localVariables)

Inserts a Opcodes.F_APPEND frame.

Parameters:

methodVisitor - The method visitor to write to.

appended - The appended local variables.

localVariables - The local variables that are defined at this frame location, excluding the ones appended.

chop

public void chop(MethodVisitor methodVisitor,

                 List<? extends TypeDefinition> localVariables)

Inserts a Opcodes.F_CHOP frame.

Parameters:

methodVisitor - The method visitor to write to.

chopped - The number of chopped values.

localVariables - The local variables that are defined at this frame location, excluding the chopped variables.

full
