conforms

public static boolean conforms(Operator o)

InstructionFormat identification method for NewArray.

Parameters:

o - an instruction

Returns:

true if the InstructionFormat of the argument operator is NewArray or false if it is not.

getResult

public static RegisterOperand getResult(Instruction i)

Get the operand called Result 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 Result

getClearResult

public static RegisterOperand getClearResult(Instruction i)

Get the operand called Result 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 Result

setResult

public static void setResult(Instruction i,
                             RegisterOperand Result)

Set the operand called Result 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

Result - the operand to store

indexOfResult

public static int indexOfResult(Instruction i)

Return the index of the operand called Result in the argument instruction.

Parameters:

i - the instruction to access.

Returns:

the index of the operand called Result in the argument instruction

hasResult

public static boolean hasResult(Instruction i)

Does the argument instruction have a non-null operand named Result?

Parameters:

i - the instruction to access.

Returns:

true if the instruction has an non-null operand named Result or false if it does not.

getType

public static TypeOperand getType(Instruction i)

Get the operand called Type 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 Type

getClearType

public static TypeOperand getClearType(Instruction i)

Get the operand called Type 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 Type

setType

public static void setType(Instruction i,
                           TypeOperand Type)

Set the operand called Type 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

Type - the operand to store

indexOfType

public static int indexOfType(Instruction i)

Return the index of the operand called Type in the argument instruction.

Parameters:

i - the instruction to access.

Returns:

the index of the operand called Type in the argument instruction

hasType

public static boolean hasType(Instruction i)

Does the argument instruction have a non-null operand named Type?

Parameters:
