public class CodeAttribute

extends Attribute

This class describes the information for a code attribute ($4.7.3) TBD: replace the byte array representing the code by a code class thorugh which easily the code may be changed an extended and all the indices may be checked (as with the constant pool)

Constructor Detail

CodeAttribute

protected CodeAttribute(java.io.DataInputStream dis,
                        ConstantPool cp,
                        int length)
                 throws java.io.IOException

Creates a CodeAttribute and initializes it from a DataInputStream The attribute name and length of the attribute information was already read.

---

CodeAttribute

public CodeAttribute(com.chaoswg.xtc4y.classdesc.code.Code code)

Construct a new code attribute with default values except the code part. The exceptions and attributes are initializes to be empty

Method Detail

writeAttribute

protected void writeAttribute(java.io.DataOutputStream dos,
                              ConstantPool cp)
                       throws java.io.IOException

Write the attribute information onto the DataOutputStream, using the constant pool to register variables. The Attribute name and the length of the information will already be written. A specific attribute implementation should overwrite this method.
