刚学,还不太懂,
这是我EJB里自动产生的public class LineinfoPK
implements Serializable {
public String substaid;
public String lineid;
public LineinfoPK() {
} public LineinfoPK(String substaid, String lineid) {
this.substaid = substaid;
this.lineid = lineid;
} public boolean equals(Object obj) {
if (this == obj)
return true;
if (! (obj instanceof LineinfoPK))
return false;
LineinfoPK that = (LineinfoPK) obj;
if (! (that.substaid == null ? this.substaid == null :
that.substaid.equals(this.substaid)))
return false;
if (! (that.lineid == null ? this.lineid == null :
that.lineid.equals(this.lineid)))
return false;
return true;
} public int hashCode() {
int result = 17;
result = 37 * result + this.substaid.hashCode();
result = 37 * result + this.lineid.hashCode();
return result;
}
}
