NullPointerException - This exception is overriden by an UnsupportedOperationException.

getValue

public Value getValue()

The value of the item. The value is expressed according to one of the types supported by the fr.gael.drb.value package. Generally these types correspond to primitive types (e.g. integer, floatting points, etc.) or very low level types (e.g. string, date, etc.). On the contrary to DOM implementation all the types are allowed even the arrays, date etc. Only the Value.NULL_ID type is forbidden.

Specified by:

getValue in interface DrbItem

Returns:

The value of the attribute.

setValue

public Value setValue(Value value)
               throws NullPointerException,
                      ClassCastException,
                      UnsupportedOperationException

Changes the value of the item. This operation sets a new value of the current item.The value type of the item shall be compatible with the item implementation. If the type does not match exactly it is casted to a compatible one based on the the fr.gael.drb.value capabilities. A reference to the effectivelly assigned value is returned by the operation so it is possible to check if a cast has been performed and therefore assess the accuracy of the assignement. If the cast is not possible the operation raises an UnsupportedOperationException. If the assignment is possible and the item implementation has a physical representation the value is updated in the physical source in order to persist among sessions. It therefore possible that this operation consumses an variable time.

Specified by:

setValue in interface DrbItem

Parameters:

value - The new value of the node. This value shall not be null.

Returns:

The effectivelly assigned value. The type of this value may differ from the input one.

Throws:

NullPointerException - This exception is raised when the passed reference to the value is null. This exception may be overriden by an UnsupportedOperationException.

ClassCastException - This exception is raised when the implementation has not succeeded to cast the input value in a type compatible with the current node.

UnsupportedOperationException - This exception is raised when the implementation does not support the requested assignment for any reason.

toNumeric

public Numeric toNumeric()
                  throws ClassCastException

Convert the value into the numeric type. In case of identity conversion the value itself should be returned. If the conversion is not allowed a ClassCastException is thrown.

Returns:

The converted value.

Throws:

ClassCastException - is the convertion is impossible
