public voidread(java.io.DataInputStream cpStream)
read a constant pool entry from a class stream.

param
cpStream the DataInputStream which contains the constant pool entry to be read.
exception
IOException if there is a problem reading the entry from the stream.

        classIndex = cpStream.readUnsignedShort();
        nameAndTypeIndex = cpStream.readUnsignedShort();
public voidresolve(ConstantPool constantPool)
Resolve this constant pool entry with respect to its dependents in the constant pool.

param
constantPool the constant pool of which this entry is a member and against which this entry is to be resolved.

        ClassCPInfo fieldClass
            = (ClassCPInfo) constantPool.getEntry(classIndex);

        fieldClass.resolve(constantPool);

        fieldClassName = fieldClass.getClassName();

        NameAndTypeCPInfo nt
            = (NameAndTypeCPInfo) constantPool.getEntry(nameAndTypeIndex);

        nt.resolve(constantPool);

        fieldName = nt.getName();
        fieldType = nt.getType();

        super.resolve(constantPool);
public java.lang.StringtoString()
Print a readable version of the constant pool entry.

return
the string representation of this constant pool entry.
