smbdav.filters
Class NotFilter

java.lang.Object
  smbdav.filters.NotFilter

All Implemented Interfaces:

DavenportFileFilter, jcifs.smb.SmbFileFilter

public class NotFilter

extends java.lang.Object

implements DavenportFileFilter

This class inverts the result of an underlying filter; a file will be accepted by the filter only if the underlying filter rejects the file. This is effectively a logical NOT.

This filter accepts a filter parameter containing the underlying filter class. If the filter class implements the smbdav.DavenportFileFilter interface, the instance will be initialized with a copy of this filter's properties (excluding the "filter" property itself). For example:

 <init-param>
     <param-name>fileFilters</param-name>
     <param-value>myNotFilter</param-value> 
 </init-param>
 <init-param>
     <param-name>myNotFilter</param-name>
     <param-value>smbdav.filters.NotFilter</param-value> 
 </init-param>
 <init-param>
     <param-name>myNotFilter.filter</param-name>
     <param-value>com.foo.MyFilter</param-value> 
 </init-param>
 <init-param>
     <param-name>myNotFilter.subProperty</param-name>
     <param-value>subValue</param-value> 
 </init-param>
 

The fileFilters parameter declares a single NotFilter ("myNotFilter"). This filter is passed the "filter" property, specifying com.foo.MyFilter as the subfilter class. This subfilter class is instantiated, and provided a copy of this filter's properties (containing the single property "subProperty" with the value "subValue"). Note that the "filter" property is removed from the properties copy provided to the subfilter.
