RowId

public interface RowId

java.sql.RowId


Maps SQL's ROWID type into Java.

Summary

Public methods

abstract boolean equals(Object obj)

Compares this instance with the specified object and indicates if they are equal.

abstract byte[] getBytes()

Returns an array of bytes representing the value of the corresponding SQL ROWID.

abstract int hashCode()

Returns an integer hash code for this object.

abstract String toString()

Returns a string containing a concise, human-readable description of this object.

Public methods

equals

Added in API level 9
boolean equals (Object obj)

Compares this instance with the specified object and indicates if they are equal. In order to be equal, o must represent the same object as this instance using a class-specific comparison. The general contract is that this comparison should be reflexive, symmetric, and transitive. Also, no object reference other than null is equal to null.

The default implementation returns true only if this == o. See Writing a correct equals method if you intend implementing your own equals method.

The general contract for the equals and hashCode() methods is that if equals returns true for any two objects, then hashCode() must return the same value for these objects. This means that subclasses of Object usually override either both methods or neither of them.

Parameters
obj Object: the object to compare this instance with.
Returns
boolean true if the specified object is equal to this Object; false otherwise.

getBytes

Added in API level 9
byte[] getBytes ()

Returns an array of bytes representing the value of the corresponding SQL ROWID.

Returns
byte[]

hashCode

Added in API level 9
int hashCode ()

Returns an integer hash code for this object. By contract, any two objects for which equals(Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

Note that hash values must not change over time unless information used in equals comparisons also changes.

See Writing a correct hashCode method if you intend implementing your own hashCode method.

Returns
int this object's hash code.

toString

Added in API level 9
String toString ()

Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression:

   getClass().getName() + '@' + Integer.toHexString(hashCode())

See Writing a useful toString method if you intend implementing your own toString method.

Returns
String a printable representation of this object.
