ClassFile
public class ClassFile implements ClassConstants(Code)
This is a representation of the data in a Java class-file (*.class). A ClassFile instance representing a *.class file can be generated using the static create(DataInput) method, manipulated using various operators, and persisted back using the write(DataOutput) method.
