Field Accessor Methods
The Value property of a Field object gets or sets the content of that object. The content is represented as a VARIANT, a type of object that can be assigned a value and any of several data types.
ADO/WFC implements the Value property with the getValue method, which returns a VARIANT object; and the setValue method, which takes a VARIANT as an argument. VARIANTs are highly efficient in certain languages, such as Microsoft Visual Basic.
In addition to the Value property, ADO/WFC provides accessor methods that use Java data types to get and set the content of Field objects. Most of these methods have names of the form getDataType or setDataType.
There are two noteworthy exceptions: One of the getObject methods returns an object coerced into a specified class. There is no getNull property; instead, there is an isNull property that returns a Boolean value indicating whether the field is null.
