      • onPropDispose

        protected void onPropDispose()

      • getValueClasses

        public java.lang.Class<?>[] getValueClasses()
        Gets the list of possible native Java classes that can be used to set a value using setPropertyValue, in order of importance.
        Specified by:
        getValueClasses in interface IGProp<java.lang.Object>
        Specified by:
        getValueClasses in class GProp<java.lang.Object>
        The array of Java classes that can be accepted in the setPropertyValue method. The first type is the "native" or most preferred type. The array is at least one item in length and never null.
      • clone

        public TypesContainer clone()
                             throws java.lang.CloneNotSupportedException
        Creates a clone out of this property. The cloning is overridden by the subclasses in order to handle cloning of its class variables appropriately.
        clone in class GProp<java.lang.Object>
        java.lang.CloneNotSupportedException - If a subclass doesn't allow cloning, e.g. the client properties.
      • validatePropType

        public void validatePropType​(java.lang.Object newValue)
                              throws PropTypeException
        Validates that the value to set is of Map<?,?> instance. Later, when setting the property, the method modifyPropertyValue will be called, and this one will require the type Map<String,IzTypeDeclaration> in order not to throw PropertyException.
        Specified by:
        validatePropType in interface IGProp<java.lang.Object>
        Specified by:
        validatePropType in class GProp<java.lang.Object>
        newValue - The new value to set.
        PropTypeException - if newValue is not of Map<String,IzTypeDeclaration> instance.
      • appendPropValue

        protected void appendPropValue​(PropMgr propertyManager,
                                       SendTransaction trans,
                                       java.lang.Object value)
        Appends the string array to an outgoing transaction.
        Specified by:
        appendPropValue in class GProp<java.lang.Object>
        propertyManager - the property manager instance.
        trans - transaction to append the properties to.
        value - the value to append to the transaction, a reference to the current property value.
      • initializeValue

        public boolean initializeValue​(PropMgr propertyManager,
                                       ReadTransaction trans)
        Initializes the property value from a transaction.
        Specified by:
        initializeValue in class GProp<java.lang.Object>
        propertyManager - the property manager.
        trans - the transaction to initialize the property with.
        true if the value has changed, false otherwise.
      • initializeProp

        public void initializeProp​(org.w3c.dom.Element element)
                            throws PropException
        Called to initialize the property from an Element. The property should initialize itself from attributes and nodes with appropriate information.

        This element creates sub-elements "item" that holds a text node.

        initializeProp in class GProp<java.lang.Object>
        element - The Element.
        PropException - when the initialization fails.
      • initializeElement

        protected void initializeElement​(org.w3c.dom.Element element)
        Called when the XML file for the property tree is serialized from properties. The property should fill attributes and nodes with appropriate information.

        The attribute "sort" may be set to "client", "server" or not present, i.e. no sorting. The setting "server" indicates that the Server provides the sorting rule to use, settable for each client session programmatically.

        After the element, elements "entry" builds up all text entries containing the strings in "key" and "value" attributes.

        initializeElement in class GProp<java.lang.Object>
        element - The Element to initialize.
      • getPropValue0

        protected java.lang.Object getPropValue0​(java.lang.Object value,
                                                 int index)
                                          throws java.lang.Exception
        Gets the property value in another class form than the "native" one. This method tries conversion of a "native" property value into another class type. This method is used when filling in a POJO variable (Plain Old Java Object Field) from a "native" property value.
        Specified by:
        getPropValue0 in class GProp<java.lang.Object>
        value - The property value.
        index - The index in the Class array returned by getValueClasses().
        The property value in the requested class, after conversion.
        java.lang.Exception - Other exceptions that could occur.
      • toNativeValue0

        protected java.lang.Object toNativeValue0​(java.lang.Object value,
                                                  int index)
                                           throws java.lang.Exception
        Tries conversion of possibly accepted properties values using the setPropertyValue method into the most preferred property value type. If the input value already is of the preferred type, the same object is returned.
        Specified by:
        toNativeValue0 in class GProp<java.lang.Object>
        value - The input value to convert to native value.
        index - The index in the array returned by getValueClasses(), or -1 if not found.
        The converted input value in the preferred property value object type.
        java.lang.Exception - For conversion exceptions.
