Constructor Detail

MultiANewArrayInstruction

public MultiANewArrayInstruction(ConstPool constPool,
                                 int opcode,
                                 int offset,
                                 int classIndex,
                                 int dimensions)

Constructs a MultiANewArrayInstruction.

Parameters:

constPool - The constant pool associated with the class.

opcode - The opcode of the instruction.

offset - The bytecode offset of the instruction.

classIndex - The constant pool index for the class reference.

dimensions - The number of dimensions for the new array.

Method Detail

getClassIndex

public int getClassIndex()

Returns:

the class index

getDimensions

public int getDimensions()

Returns:

the dimensions

accept

public void accept(AbstractBytecodeVisitor visitor)

Description copied from class: Instruction

Accepts a visitor for bytecode analysis.

Specified by:

accept in class Instruction

Parameters:

visitor - The visitor to accept.

write

public void write(DataOutputStream dos)
           throws IOException

Writes the MULTIANEWARRAY opcode and its operands to the DataOutputStream.

Specified by:

write in class Instruction

Parameters:

dos - The DataOutputStream to write to.

Throws:

IOException - If an I/O error occurs.

getStackChange

public int getStackChange()

Returns the change in stack size caused by this instruction.

Specified by:

getStackChange in class Instruction

Returns:

The stack size change (pops dimensions count from stack, pushes array reference).

getLocalChange

public int getLocalChange()

Returns the change in local variables caused by this instruction.

Specified by:

getLocalChange in class Instruction

Returns:

The local variables size change (none).

resolveClass

public String resolveClass()

Resolves and returns a string representation of the array class.

Returns:

The array class as a string.

toString

public String toString()

Returns a string representation of the instruction.

Overrides:

toString in class Instruction

Returns:

The mnemonic, class index, dimensions, and resolved class.
