Constructor Detail

LocationCarrier

public LocationCarrier()
Method Detail

conforms

public static boolean conforms(Instruction i)
Does the instruction belong to an instruction format that has an operand called Location?

Parameters:
i - the instruction to test
Returns:
true if the instruction's instruction format has an operand called Location and false if it does not.

conforms

public static boolean conforms(Operator o)
Does the operator belong to an instruction format that has an operand called Location?

Parameters:
o - the operator to test
Returns:
true if the instruction's instruction format has an operand called Location and false if it does not.

getLocation

public static LocationOperand getLocation(Instruction i)
Get the operand called Location from the argument instruction. Note that the returned operand will still point to its containing instruction.

Parameters:
i - the instruction to fetch the operand from
Returns:
the operand called Location

getClearLocation

public static LocationOperand getClearLocation(Instruction i)
Get the operand called Location from the argument instruction clearing its instruction pointer. The returned operand will not point to any containing instruction.

Parameters:
i - the instruction to fetch the operand from
Returns:
the operand called Location

setLocation

public static void setLocation(Instruction i,
                               LocationOperand op)
Set the operand called Location in the argument instruction to the argument operand. The operand will now point to the argument instruction as its containing instruction.

Parameters:
i - the instruction in which to store the operand
op - the operand to store

indexOfLocation

public static int indexOfLocation(Instruction i)
Return the index of the operand called Location in the argument instruction.

Parameters:
i - the instruction to access.
Returns:
the index of the operand called Location in the argument instruction

hasLocation

public static boolean hasLocation(Instruction i)
Does the argument instruction have a non-null operand named Location?

Parameters:
i - the instruction to access.
Returns:
true if the instruction has an non-null operand named Location or false if it does not.
