Method Details

isValidShape

public static boolean isValidShape(int opcode)

Determines if the given opcode has the right "shape" to be valid. This includes the range 0x01..0xfe, the range 0x00ff..0xffff where the low-order byte is either 0 or 0xff, and the special opcode values SPECIAL_FORMAT and NO_NEXT. Note that not all of the opcode values that pass this test are in fact used. This method is meant to perform a quick check to reject blatantly wrong values (e.g. when validating arguments).

Parameters:

opcode - the opcode value

Returns:

true iff the value has the right "shape" to be possibly valid

extractOpcodeFromUnit

public static int extractOpcodeFromUnit(int opcodeUnit)

Gets the opcode out of an opcode unit, the latter of which may also include one or more argument values.

Parameters:

opcodeUnit - the opcode-containing code unit

Returns:

the extracted opcode
