Class OrFilter

  extended bysmbdav.filters.OrFilter
All Implemented Interfaces:
DavenportFileFilter, jcifs.smb.SmbFileFilter

public class OrFilter
extends java.lang.Object
implements DavenportFileFilter

This class chains one or more underlying filters together; a file will be accepted if any subfilters accept the file. This is effectively a logical OR.

Subfilters are installed using a mechanism very similar to the global filter installation; this filter accepts a fileFilters parameter containing a list of whitespace-separated subfilter names. An additional parameter is specified for each name, indicating the filter class. If the filter class implements the smbdav.DavenportFileFilter interface, the instance will be initialized using a java.util.Properties object containing name-value pairs from this filter's properties, scoped by the subfilter's name. For example:


The fileFilters parameter declares a single OrFilter ("myOrFilter"). This filter is passed its own "fileFilters" property, containing the single subfilter name "mySubFilter". A corresponding property is provided, specifying as the subfilter class. This subfilter class is instantiated, and provided its own set of properties (containing the single property "subProperty" with the value "subValue"). Note that the subfilter's namespace prefix ("mySubFilter.") will be stripped off when the properties are delivered to the subfilter instance.
