Clears the values in this AttributeImpl and resets it to its default value. If this implementation implements more than one Attribute interface it clears all.

Shallow clone. Subclasses must override this if they need to clone any members deeply,

Copies the values from this Attribute into the passed-in target attribute. The target implementation must support all the Attributes this implementation supports.

All values used for computation of {@link #hashCode()} should be checked here for equality. see also {@link Object#equals(Object)}

Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.

Subclasses must implement this method and should compute a hashCode similar to this:

            public int hashCode() {
            int code = startOffset;
            code = code * 31 + endOffset;
            return code;
            }
            

see also {@link #equals(Object)}

Gets the Type of the current instance.

Creates a shallow copy of the current Object.

The default implementation of this method accesses all declared fields of this object and prints the values in the following syntax:

            public String toString() {
            return "start=" + startOffset + ",end=" + endOffset;
            }
            

This method may be overridden by subclasses.
