Method Detail

values

public static final Opcode[] values()

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

for(Opcode c : Opcode.values())
        System.out.println(c);

Returns:

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

valueOf

public static Opcode valueOf(java.lang.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:

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

callCodes

public static Opcode[] callCodes()

Get an array of codes for subclasses of AbstractCall.

code

public int code()

Get the Opcode code for storing the integer value in the database.

createInstr

public abstract Bytecode createInstr(int cu,
                                     int addr)

Create a Bytecode instruction object of the appropriate subclass for this Opcode.

get

public static Opcode get(int code)

Get the Opcode enum object for a given Opcode code out of the database.

isCall

public boolean isCall()

Is this opcode used as a subclass of AbstractCall?

toString

public java.lang.String toString()

Get the lowercase name of the opCode (more suitable for printing).

Overrides:

toString in class java.lang.Enum<Opcode>
