match

public boolean match(Attributes attributes,
                     String filter)
              throws DirectoryException

Check whether a raw string filter expression matches on the given LDAP entry.

Parameters:

attributes - the ldap entry to match

filter - a raw string filter expression (eg. (!(&(attr1=*)(attr2=value2)(attr3=val*))) )

Returns:

true if the ldap entry matches the filter

Throws:

DirectoryException - if the filter is not a valid LDAP filter

simpleMatch

protected static boolean simpleMatch(Attributes attributes,
                                     org.apache.directory.shared.ldap.filter.SimpleNode simpleElement)
                              throws DirectoryException

Handle simple equality test on any non-null value (eg: (attr2=value2)).

Returns:

true if the equality holds

Throws:

DirectoryException

isCaseSensitiveMatch

protected static boolean isCaseSensitiveMatch(Attribute attribute)

isCaseSensitiveSubstringMatch

protected static boolean isCaseSensitiveSubstringMatch(Attribute attribute)

substringMatch

protected boolean substringMatch(Attributes attributes,
                                 org.apache.directory.shared.ldap.filter.SubstringNode substringElement)
                          throws DirectoryException

Implement the substring match on any non-null value of a string attribute (eg: (attr3=val*)).

Returns:

the result of the regex evaluation
