Method Detail

hasMoreOpcode

boolean hasMoreOpcode()

Tests if there are more instruction opcode available from this bytecode parser. If this method returns true, then a subsequent call to nextOpcode with no argument will successfully return an instruction opcode.

Returns:

true if and only if there is at least one opcode in the bytecode after the current position; false otherwise.

nextOpcode

int nextOpcode()

Returns the next instruction opcode read from this bytecode parser. If this instruction has operands, they can be read with the readOperands method.

Returns:

the next instruction opcode from this bytecode parser

Throws:

java.util.NoSuchElementException - if there are no more instruction opcode in this bytecode parser

See Also:

readOperands(byte[], int, int)

getMnemonic

java.lang.String getMnemonic()

Returns the mnemonic of the next instruction opcode read from this bytecode parser. This method does not change the instruction opcodes flow.

Returns:

the mnemonic of the instruction opcode read from this bytecode parser

getPosition

int getPosition()

Returns the current opcode position in the bytecodes flow.

readOperands

int readOperands(byte[] b,
                 int off,
                 int len)

Reads up to len operand of the current instruction, read with the nextOpcode method, into an array of bytes. An attempt is made to read as many as len operand bytes, but a smaller number may be read, possibly zero if the current instruction is without operand. The number of operands actually read is returned as an integer.

Parameters:

b - the buffer into which the operands are read.

off - the start offset in array b at which the operands are written

len - the maximum number of operands to read

Returns:

the total number of bytes read into the buffer

getOpcodeCount

int getOpcodeCount()

Calculates the number of times that this bytecode parser's nextOpcode method can be called before it generates an exception. The current position is not advanced.

Returns:

the number of instructions opcode remaining in the bytecode

getOperandCount

int getOperandCount()

Returns the number of operands of the current instruction read with the nextOpcode method.

Returns:

the number of operands of the current instruction

fillInput

void fillInput(byte[] b,
               int off,
               int len)

Resets the bytecode parsing and initializes it with the len bytes of the specified bytes array, starting at the off position.

Parameters:

b - the bytecode of a method

off - the start offset in array b at which the parsing is processed

len - the maximum number of bytes to analyse
