- All Implemented Interfaces:
Serializable,Cloneable
public class SerialDatalink extends Object implements Serializable, Cloneable
A serialized mapping in the Java programming language of an SQLDATALINKvalue. ADATALINKvalue references a file outside of the underlying data source that the data source manages.RowSetimplementations can use the methodRowSet.getURLto retrieve ajava.net.URLobject, which can be used to manipulate the external data.java.net.URL url = rowset.getURL(1);Thread safety
A SerialDatalink is not safe for use by multiple concurrent threads. If a SerialDatalink is to be used by more than one thread then access to the SerialDatalink should be controlled by appropriate synchronization.- Since:

public URL getDatalink() throws SerialException
Returns a new URL that is a copy of thisSerialDatalinkobject.- Returns:
- a copy of this
SerialDatalinkobject as aURLobject in the Java programming language. - Throws:

equals
public boolean equals(Object obj)
Compares thisSerialDatalinkto the specified object. The result istrueif and only if the argument is notnulland is aSerialDatalinkobject whose URL is identical to this object's URL- Overrides:
equalsin classObject- Parameters:
obj- The object to compare thisSerialDatalinkagainst- Returns:
trueif the given object represents aSerialDatalinkequivalent to this SerialDatalink,falseotherwise- See Also:

hashCode
public int hashCode()
Returns a hash code for thisSerialDatalink. The hash code for aSerialDatalinkobject is taken as the hash code of theURLit stores- Overrides:
hashCodein classObject- Returns:
- a hash code value for this object.
