The applies

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

canApply

public boolean canApply(Object pUnk)
                 throws IOException,
                        AutomationException

Indicates if the receiver can apply the given object at that particular moment.

Remarks

CanApply indicates whether the specified object can be applied to the current object. For instance, we might want to ask our CircleElement whether a Color object applies to it. If it does, then we can use the Apply method to update our CircleElement with the new Color object.

CanApply differs from Applies in that it is a check for the editability of the object at any given time. Applies indicates whether an object can be applied at all, while CanApply indicates whether an object can be applied at that particular moment.

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:

canApply in interface IPropertySupport

Parameters:

pUnk - A reference to another Object (IUnknown) (in)

Returns:

The canApply

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getCurrent

public Object getCurrent(Object pUnk)
                  throws IOException,
                         AutomationException

The object currently being used.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Specified by:

getCurrent in interface IPropertySupport

Parameters:

pUnk - A reference to another Object (IUnknown) (in)

Returns:

A reference to another Object (IUnknown)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

apply

public Object apply(Object newObject)
             throws IOException,
                    AutomationException

Applies the given property to the receiver and returns the old object.

Remarks

Apply will apply the specified object to the current object. For instance, I might apply a Color object to my RectangleElement. When I execute Apply, the object I replace (the old object) is returned.

Use the Applies and CanApply methods to determine if an Apply can be used on an object.
