OSGeo::FDO::Commands::Feature::IUpdateImp Class Reference
[OSGeo::FDO::Commands::Feature]
List of all members.
Detailed Description
The
IUpdateImp class is a concrete implementation of interface
IUpdate. The
IUpdate interface defines the Update command, which modifies instances of a given class that match the specified criteria. Input to the update command includes the name of the class, the list of property name/value pairs to be updated, and the filter criteria by which to identify the instances to be updated. The filter may be specified either as text or as an expression tree (most likely produced by a query builder). The update command can update instances at global scope or nested within an object collection property. Instances at global scope are referred to simply by the class name. Instances at a nested scope (i.e., instances within an object collection property) are referred to by the containing class name, followed by a '.', followed by the object collection property name.
