public interface FilterInterface

The FilterInterface describes a means for setting and getting information used to limit the results of a search against a repository. While it would be nice to make it completely repository-neutral, there are concepts and mechanisms that just don't translate.

FILTERCOMPONENT_UNSUPPORTED

static final java.lang.String FILTERCOMPONENT_UNSUPPORTED

This string will be returned from a Filter method that returns a search string as an indicator that one more more filter components were not supported for the repository type that was searched. For instance, the GT and LT operators are not supported for OMI repositories.

Constant Field Values

FLAG_OVERRIDE

static final int FLAG_OVERRIDE

Most searches use a default set of flags that generally result in the most useful results set. Calling a method like setOMRFlags will add to those flags, but if you want to completely override them and use only those flags you provide, OR this flag value with your flags and only yours will be used.

addProtocol

void addProtocol(java.lang.String protocol)

Remove a protocol from the list.

Get the explicit search string set by the client. This overrides the filter components.

Add a search option. Search options are generally protocol-specific, so details of what options are supported are described in the repository implementation documentation.

Parameters:

name - The name of the option to be added.

option - The option value. This is usually a String, but may be other object types.

removeSearchOption

void removeSearchOption(java.lang.String name)
