Method Detail

getIdentityMappings

public static List<IdentityMapping> getIdentityMappings(NiFiRegistryProperties properties)

Builds the identity mappings from NiFiRegistryProperties.

Parameters:

properties - the NiFiRegistryProperties instance

Returns:

a list of identity mappings

getGroupMappings

public static List<IdentityMapping> getGroupMappings(NiFiRegistryProperties properties)

Buils the group mappings from NiFiProperties.

Parameters:

properties - the NiFiProperties instance

Returns:

a list of group mappings

getMappings

private static List<IdentityMapping> getMappings(NiFiRegistryProperties properties,
                                                 String patternPrefix,
                                                 String valuePrefix,
                                                 String transformPrefix,
                                                 Supplier<String> getSubject)

Builds the identity mappings from NiFiRegistryProperties.

Parameters:

properties - the NiFiRegistryProperties instance

Returns:

a list of identity mappings

mapIdentity

public static String mapIdentity(String identity,
                                 List<IdentityMapping> mappings)

Checks the given identity against each provided mapping and performs the mapping using the first one that matches. If none match then the identity is returned as is.

Parameters:

identity - the identity to map

mappings - the mappings

Returns:

the mapped identity, or the same identity if no mappings matched

escapeLiteralBackReferences

private static String escapeLiteralBackReferences(String unescaped,
                                                  int numCapturingGroups)
