Examples of org.rssowl.core.persist.ISearchField

org.rssowl.core.persist.ISearchField

Instances of ISearchField describe the target field for a search condition. The field is described by its identifier in the system and a human-readable name, used in the UI.

A call to getSearchValueType() will give Information of the data-type the field is using. This information can be used for validating the search-value and to perform the search in the persistance layer.
