MULTIANEWARRAY

MULTIANEWARRAY()

Empty constructor needed for Instruction.readInstruction. Not to be used otherwise.

MULTIANEWARRAY

public MULTIANEWARRAY(int index,
                      short dimensions)

Method Detail

dump

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

Dump instruction as byte code to stream out.

Overrides:

dump in class CPInstruction

Parameters:

out - Output stream

Throws:

java.io.IOException

initFromFile

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

Read needed data (i.e., no. dimension) from file.

Overrides:

initFromFile in class CPInstruction

Parameters:

bytes - input stream

wide - wide prefix?

Throws:

java.io.IOException - may be thrown if the implementation needs to read data from the file

getDimensions

public final short getDimensions()

Returns:

number of dimensions to be created

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)

Overrides:

toString in class CPInstruction

Returns:

mnemonic for instruction with symbolic references resolved

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

Returns:

Number of words consumed from stack by this instruction

getExceptions

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

Specified by:

getExceptions in interface ExceptionThrower

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

Returns:

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

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, i.e., the most specific visitXXX() call comes last.

Specified by:

accept in class Instruction

Parameters:

v - Visitor object
