Constructor Detail

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

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

Following copied from class: de.fub.bytecode.generic.CPInstruction

Parameters:

bytes - input stream

wide - wide prefix?

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

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

Following copied from interface: de.fub.bytecode.generic.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.

Overrides:

accept in class Instruction

Parameters:

v - Visitor object
