Class RecursiveSearchResultHandler

java.lang.Object
  edu.vt.middleware.ldap.handler.AbstractResultHandler<T,T>
      edu.vt.middleware.ldap.handler.CopyResultHandler<SearchResult>
          edu.vt.middleware.ldap.handler.CopySearchResultHandler
              edu.vt.middleware.ldap.handler.RecursiveSearchResultHandler

All Implemented Interfaces:

ExtendedSearchResultHandler, ResultHandler<SearchResult,SearchResult>, SearchResultHandler

public class RecursiveSearchResultHandler
extends CopySearchResultHandler
implements ExtendedSearchResultHandler

RecursiveSearchResultHandler recursively searches based on a supplied attribute and merges those results into the original result set. For the following LDIF:

   dn: uugid=group1,ou=groups,dc=vt,dc=edu
   uugid: group1
   member: uugid=group2,ou=groups,dc=vt,dc=edu

   dn: uugid=group2,ou=groups,dc=vt,dc=edu
   uugid: group2
 

With the following code:

   RecursiveSearchResultHandler rsh = new RecurseSearchResultHandler(
     ldap, "member", new String[]{"uugid"});
 

Will produce this result for the query (uugid=group1):

   dn: uugid=group1,ou=groups,dc=vt,dc=edu
   uugid: group1
   uugid: group2
   member: uugid=group2,ou=groups,dc=vt,dc=edu

public RecursiveSearchResultHandler()

Default constructor.

RecursiveSearchResultHandler

public RecursiveSearchResultHandler(String searchAttr,
                                    String[] mergeAttrs)

Creates a new RecursiveAttributeHandler with the supplied search attribute and merge attributes.

Parameters:

searchAttr - String

mergeAttrs - String[]

RecursiveSearchResultHandler

public RecursiveSearchResultHandler(Ldap l,
                                    String searchAttr,
                                    String[] mergeAttrs)

Creates a new RecursiveAttributeHandler with the supplied ldap, search attribute, and merge attributes.

Parameters:

l - Ldap

searchAttr - String

mergeAttrs - String[]

Method Detail

getSearchResultLdap

public Ldap getSearchResultLdap()

Gets the Ldap used by the search operation invoking this handler.

Specified by:

getSearchResultLdap in interface ExtendedSearchResultHandler

Returns:

Ldap

setSearchResultLdap

public void setSearchResultLdap(Ldap l)

Sets the Ldap used by the search operation invoking this handler.

Specified by:

setSearchResultLdap in interface ExtendedSearchResultHandler

Parameters:

l - Ldap

getSearchAttribute

public String getSearchAttribute()

Returns the attribute name that will be recursively searched on.

Returns:

String attribute name

setSearchAttribute

public void setSearchAttribute(String s)

Sets the attribute name that will be recursively searched on.

Parameters:

s - String

getMergeAttributes

public String[] getMergeAttributes()

Returns the attribute names that will be merged by the recursive search.

Returns:

String[] attribute names

setMergeAttributes

public void setMergeAttributes(String[] s)

Sets the attribute name that will be merged by the recursive search.

Parameters:

s - String[]

initalizeReturnAttributes

protected void initalizeReturnAttributes()

Initializes the return attributes array. Must be called after both searchAttribute and mergeAttributes have been set.

process

public List<SearchResult> process(SearchCriteria sc,
                                  NamingEnumeration<? extends SearchResult> en,
