Enum Constant Detail

IMMEDIATE_VALUE

public static final ShortOperandType IMMEDIATE_VALUE

Immediate short value.

IGNORE

public static final ShortOperandType IGNORE

Ignored value.

INC_CONST

public static final ShortOperandType INC_CONST

Increment byte value (for wide iinc).

LOCAL_VARIABLE_INDEX

public static final ShortOperandType LOCAL_VARIABLE_INDEX

Index into the local variable table.

RUNTIME_CONSTANT_INDEX

public static final ShortOperandType RUNTIME_CONSTANT_INDEX

Method Detail

values

public static ShortOperandType[] 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 (ShortOperandType c : ShortOperandType.values())
    System.out.println(c);

Returns:

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

valueOf

public static ShortOperandType 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

java.lang.NullPointerException - if the argument is null

type

public char type()

Description copied from interface: OperandType

Gets the operand's type (B:byte, S:short, I:int).

Specified by:

type in interface OperandType

Returns:

the operand's type (B:byte, S:short, I:int).

decode

public void decode(int pc,
                   de.carne.mcd.io.MCDInputBuffer buffer,
                   de.carne.mcd.io.MCDOutputBuffer out)
            throws java.io.IOException

Description copied from interface: OperandType

Decodes the operand.

Specified by:

decode in interface OperandType

Parameters:

pc - the program counter of the corresponding opcode.

buffer - the MCDInputBuffer to decode from.

out - the MCDOutputBuffer to decode to.

Throws:

java.io.IOException - if an I/O error occurs.
