Constructor Detail

MULTIANEWARRAY

public MULTIANEWARRAY(int index,
                      short dimensions)

Constructs a MULTIANEWARRAY instruction.

Parameters:

index - index into constant pool.

dimensions - number of dimensions.

Method Detail

accept

public void accept(Visitor v)

Call corresponding visitor method(s). The order is: Call visitor methods of implemented interfaces first, then call methods according to the class hierarchy in descending order, that is, the most specific visitXXX() call comes last.

Specified by:

accept in class Instruction

Parameters:

v - Visitor object.

consumeStack

public int consumeStack(ConstantPoolGen cpg)

Also works for instructions whose stack effect depends on the constant pool entry they reference.

Overrides:

consumeStack in class Instruction

Parameters:

cpg - The constant pool generator.

Returns:

Number of words consumed from stack by this instruction.

dump

public void dump(java.io.DataOutputStream out)
          throws java.io.IOException

Dumps instruction as byte code to stream out.

Overrides:

dump in class CPInstruction

Parameters:

out - Output stream.

Throws:

java.io.IOException - Thrown when an I/O exception of some sort has occurred.

getDimensions

public final short getDimensions()

Gets the number of dimensions.

Returns:

number of dimensions to be created.

getExceptions

public java.lang.Class<?>[] getExceptions()

Description copied from interface: ExceptionThrower

Gets the exceptions that may be thrown by this instruction.

Specified by:

getExceptions in interface ExceptionThrower

Returns:

The exceptions that may be thrown by this instruction.

getLoadClassType

public ObjectType getLoadClassType(ConstantPoolGen cpg)

Description copied from interface: LoadClass

Returns the ObjectType of the referenced class or interface that may be loaded and resolved.

Specified by:

getLoadClassType in interface LoadClass

Parameters:

cpg - A ConstantPoolGen.

Returns:

object type that may be loaded or null if a primitive is referenced.

initFromFile

protected void initFromFile(ByteSequence bytes,
                            boolean wide)
                     throws java.io.IOException

Reads needed data (that is, no. dimension) from file.

Overrides:

initFromFile in class CPInstruction

Parameters:

bytes - input stream.

wide - wide prefix?.

Throws:

java.io.IOException - Thrown if the implementation needs to read data from the file

toString

public java.lang.String toString(boolean verbose)

Description copied from class: CPInstruction

Long output format: <name of opcode> "["<opcode number>"]" "("<length of instruction>")" "<"< constant pool index>">"

Overrides:

toString in class CPInstruction

Parameters:

verbose - long/short format switch.

Returns:

mnemonic for instruction.

toString

public java.lang.String toString(ConstantPool cp)

Description copied from class: Instruction

Gets the mnemonic for instruction with symbolic references resolved.

Overrides:

toString in class CPInstruction

Parameters:

cp - The constant pool.

Returns:

mnemonic for instruction with symbolic references resolved.
