adds semantic checks to the default deserialization method . this method must have the standard signature for a readobject method , and the body of the method must begin with `` s.defaultreadobject ; '' . other than that , any semantic checks can be specified and do not need to stay the same from version to version . a readobject method of this form may be added to any class , even if tetrad sessions were previously saved out using a version of the class that did n't include it . that 's what the `` s.defaultreadobject ; '' is for . see j. bloch , effective java , for help . concode_field_sep long serialVersionUID concode_elem_sep int varsPerInd concode_elem_sep int mlag concode_field_sep ManualLagGraphParams serializableInstance concode_elem_sep int getVarsPerInd concode_elem_sep void setVarsPerInd concode_elem_sep int getMlag concode_elem_sep void setMlag
