Interface AttributeFilter

All Superinterfaces:

Serializable

public interface AttributeFilter
extends Serializable

Defines the attribute filter that can be used when retrieving the attributes of a feature. The attribute filter is used to modify the properties of an attribute. A user can implement the filter to remove certain attributes from the list of editable attributes or modify the properties of certain attributes. To apply this filter, any method that retrieves the features of a layer must invoke it. The user must implement the filter method that will be called for each attribute retrieved from the feature class. For details see EditUtil.getAttributes.
