TLcdDataPropertyValueContext

public TLcdDataPropertyValueContext(Object aValue,
                                    String aExpression,
                                    ILcdDataObject aDataObject,
                                    ILcdModel aModel,
                                    ILcdLayer aLayer,
                                    ILcdView aView)

Creates a new context instance with the given arguments and the default expression language, an instance of TLcdDataObjectExpressionLanguage.

Parameters:

aValue - The value the domain object has/should have for the property. This may be null if this information is not available, or if the value is null.

aExpression - The expression that indicates how to locate the value in the domain object as defined by the TLcdDataObjectExpressionLanguage. The expression must not be null.

aDataObject - The domain object for which this object provides the context. This must not be null.

aModel - The ILcdModel that contains the aDomainObject. This may be null if this information is not available.

aLayer - The ILcdLayer in which aModel is displayed. This may be null if this information is not available.

aView - The ILcdView in which aLayer is displayed. This may be null if this information is not available.

                                    ILcdView aView)

Creates a new context instance with the given arguments.

Parameters:

aValue - The value the domain object has/should have for the property. This may be null if this information is not available, or if the value is null.

aExpression - The expression that indicates how to find the value in the domain object as defined by the argument aExpressionLanguage. The expression must not be null.

aExpressionLanguage - The expression language determining the meaning of the expression. The expression language must not be null.

aDataObject - The domain object for which this object provides the context. This must not be null.

aModel - The ILcdModel that contains the aDomainObject. This may be null if this information is not available.

aLayer - The ILcdLayer in which aModel is displayed. This may be null if this information is not available.

aView - The ILcdView in which aLayer is displayed. This may be null if this information is not available.
