Constructor Detail

NakedObjectActionParameterParseable

public NakedObjectActionParameterParseable(int index,
                                           NakedObjectActionImpl action,
                                           NakedObjectActionParamPeer peer)

Method Detail

getNoLines

public int getNoLines()

Description copied from interface: ParseableEntryFeature

Returns the number of lines for a multi-line value.

Specified by:

getNoLines in interface ParseableEntryFeature

canWrap

public boolean canWrap()

Description copied from interface: ParseableEntryFeature

Determines if a multi-line value can be wrapped when displayed.

Specified by:

canWrap in interface ParseableEntryFeature

getMaximumLength

public int getMaximumLength()

Description copied from interface: ParseableEntryFeature

Returns the maximum number of characters for a value of this type.

Specified by:

getMaximumLength in interface ParseableEntryFeature

getTypicalLineLength

public int getTypicalLineLength()

Description copied from interface: ParseableEntryFeature

The typical length of each line for this value, as a number of characters.

Specified by:

getTypicalLineLength in interface ParseableEntryFeature

isValid

public java.lang.String isValid(NakedObject nakedObject,
                                java.lang.Object proposedValue)

Invoked when tab away, disables the OK button.

Assumed to be invoked by user.

Specified by:

isValid in interface NakedObjectActionParameter

Returns:

getInstance

public Instance getInstance(NakedObject nakedObject)

Description copied from interface: Specification

Return an Instance of this Specification with respect to the provided NakedObject.

For example, if the Specification is a OneToOneAssociation, then is an Instance implementation representing the { NakedObject/ OneToOneAssociation } tuple.

Implementations are expected to use a double-dispatch back to the provided NakedObject (passing themselves as a parameter), using NakedObjectMM.getInstance(Specification).

Note: this method may throw an UnsupportedOperationException; see NakedObjectMM.getInstance(Specification) for details.

Specified by:

getInstance in interface Specification

get

public NakedObject get(NakedObject owner)

Gets the proposed value of the Instance (downcast as a MutableProposed, wrapping the proposed value into a NakedObject.

Specified by:

get in interface CurrentHolder

set

public void set(NakedObject owner,
                NakedObject newValue)

Sets the proposed value of the Instance (downcast as a MutableProposed, unwrapped the proposed value from a NakedObject.
