type - - see getType().

Method Detail

getType

public Class<E> getType()

Specified by:

getType in interface Id<E>

Returns:

the Class reflecting the type of the referenced entity.

hashCode

public final int hashCode()

Overrides:

hashCode in class Object

equals

public final boolean equals(Object obj)

Overrides:

equals in class Object

toString

public String toString()

Description copied from interface: Datatype

Returns the official String representation of this Datatype. While the general contract of Object.toString() is very weak and mainly used for debugging, the contract here is very strong. The returned String has to be suitable for end-users and official output to any kind of sink.
ATTENTION:
This method is not supposed to do internationalization (I18N). See NlsMessage for this purpose and implement NlsObject if you want to support I18N/L10N.

Specified by:

toString in interface Id<E>

Specified by:

toString in interface Datatype

Overrides:

toString in class Object

Returns:

the String representation of this Id. Will consist of object-id, type and revision separated with a specific separator. Segments that are null will typically be omitted in the String representation.

toString

protected void toString(StringBuilder buffer)

Parameters:

buffer - the StringBuilder where to append the string representation to.

parseUuid

protected static UUID parseUuid(String idString)

Parameters:

idString - the id (without version) as String.

Returns:

the idString as UUID or null if not a UUID (but ID instead).
