Constructor Detail

MULTIANEWARRAY

public MULTIANEWARRAY(int index,
                      short dimensions)
Method Detail

dump

public void dump(DataOutputStream out)
          throws IOException
Dump instruction as byte code to stream out.

Overrides:
dump in class CPInstruction
Parameters:
out - Output stream
Throws:
IOException

initFromFile

protected void initFromFile(ByteSequence bytes,
                            boolean wide)
                     throws IOException
Read needed data (i.e., no. dimension) from file.

Overrides:
initFromFile in class CPInstruction
Parameters:
bytes - input stream
wide - wide prefix?
Throws:
IOException

getDimensions

public final short getDimensions()
Returns:
number of dimensions to be created

toString

public 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 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 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
