Method Detail

setValue

V setValue(java.lang.String aName,
           V aValue)
           throws CannotModifyPropertyException

Sets the value for the meta data identified by the specified name.

Parameters:

aName - name of meta data to set the value for

aValue - meta data value to set; must not be null

Returns:

the former value for the name; if none existed, null is returned

Throws:

                  throws CannotModifyPropertyException

Sets the specified meta data.

Parameters:

aMetaData - meta data to set

Returns:

true if this ModifiableMetaData was changed as a result of this call

Throws:

CannotModifyPropertyException - in case a specified meta data cannot be set; in this case, the meta data are set only partially

removeName

V removeName(java.lang.String aName)
             throws CannotModifyPropertyException
