question: this is a factory method for this compositekeydepth configuration . the factory method is a best practice for the case where the actual object construction is changed in the future . concode_field_sep int depth concode_elem_sep long serialVersionUID concode_elem_sep String PROPERTY_NAME concode_field_sep int getDepth concode_elem_sep int hashCode concode_elem_sep boolean equals concode_elem_sep String getPropertyName
target: CompositeKeyDepthOption function ( int arg0 ) { return new CompositeKeyDepthOption ( arg0 ) ; }
