Method Detail

loadConstant

public static void loadConstant(InsnList cmd,
                                int i)

Add a command to the stack that loads the given integer constant. The method takes care to use the most efficient opcode.

Parameters:

cmd - the command list where to add the command.

i - the value to be loaded.

toString

public static String toString(MethodNode mn)

To string helper to get nice comments about the MethodNode.

Parameters:

mn - the method node.

Returns:

a human readable string representation describing the method node

toString

public static String toString(ClassNode classNode)

Human readable name of the class.

Parameters:

classNode - the asm class node.

Returns:

Human readable name of the class.

toString

public static String toString(ClassNode cn,
                              MethodNode mn)

Human readable name of the method.

Parameters:

cn - the asm class node.

mn - the asm method node.

Returns:

Human readable name of the class and method.

toString

public static String toString(LocalVariableNode node)

Human readable name of the local variable.

Parameters:

node - the asm local variable node.

Returns:

Human readable name of the local variable.

toString

public static String toString(int access)

Returns a string representation containing the access keywords implied by the given int. See Opcodes ACC* for the values.

Parameters:

access - the int value holding the access bits. See Opcodes ACC* for the values.

Returns:

a string representation containing the access keywords implied by the given int.
