Fields Summary
private short
dimensions
Constructors Summary
MULTIANEWARRAY()
Empty constructor needed for the Class.newInstance() statement in Instruction.readInstruction(). Not to be used otherwise.

public MULTIANEWARRAY(int index, short dimensions)
    super(com.sun.org.apache.bcel.internal.Constants.MULTIANEWARRAY, index);

    if(dimensions < 1)
      throw new ClassGenException("Invalid dimensions value: " + dimensions);

    this.dimensions = dimensions;
    length = 4;
  
Methods Summary
public voidaccept(com.sun.org.apache.bcel.internal.generic.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.
param
v Visitor object
    v.visitLoadClass(this);
    v.visitAllocationInstruction(this);
    v.visitExceptionThrower(this);
    v.visitTypedInstruction(this);
    v.visitCPInstruction(this);
    v.visitMULTIANEWARRAY(this);
  
public intconsumeStack(com.sun.org.apache.bcel.internal.generic.ConstantPoolGen cpg)
Also works for instructions whose stack effect depends on the
constant pool entry they reference.
return
Number of words consumed from stack by this instruction
 return dimensions; 
public voiddump(java.io.DataOutputStream out)
Dump instruction as byte code to stream out.
param
out Output stream
    out.writeByte(opcode);
    out.writeShort(index);
    out.writeByte(dimensions);
  
public final shortgetDimensions()
return
number of dimensions to be created
 return dimensions; 
public java.lang.Class[]getExceptions()
    Class[] cs = new Class[2 + ExceptionConstants.EXCS_CLASS_AND_INTERFACE_RESOLUTION.length];

    System.arraycopy(ExceptionConstants.EXCS_CLASS_AND_INTERFACE_RESOLUTION, 0,
		     cs, 0, ExceptionConstants.EXCS_CLASS_AND_INTERFACE_RESOLUTION.length);

    cs[ExceptionConstants.EXCS_CLASS_AND_INTERFACE_RESOLUTION.length+1] = ExceptionConstants.NEGATIVE_ARRAY_SIZE_EXCEPTION;
    cs[ExceptionConstants.EXCS_CLASS_AND_INTERFACE_RESOLUTION.length]   = ExceptionConstants.ILLEGAL_ACCESS_ERROR;

    return cs;
  
public com.sun.org.apache.bcel.internal.generic.ObjectTypegetLoadClassType(com.sun.org.apache.bcel.internal.generic.ConstantPoolGen cpg)
    Type t = getType(cpg);
    
    if (t instanceof ArrayType){
      t = ((ArrayType) t).getBasicType();
    }
    
    return (t instanceof ObjectType)? (ObjectType) t : null;
  
protected voidinitFromFile(com.sun.org.apache.bcel.internal.util.ByteSequence bytes, boolean wide)
Read needed data (i.e., no. dimension) from file.
    super.initFromFile(bytes, wide);
    dimensions = bytes.readByte();
    length     = 4;
  
public java.lang.StringtoString(boolean verbose)
return
mnemonic for instruction
    return super.toString(verbose) + " " + index + " " + dimensions;
  
public java.lang.StringtoString(com.sun.org.apache.bcel.internal.classfile.ConstantPool cp)
return
mnemonic for instruction with symbolic references resolved
    return super.toString(cp) + " " + dimensions;
