Examples of OptionsField

org.apache.directory.server.dhcp.options.OptionsField
The Dynamic Host Configuration Protocol (DHCP) provides a framework for passing configuration information to hosts on a TCP/IP network. Configuration parameters and other control information are carried in tagged data items that are stored in the 'options' field of the DHCP message. The data items themselves are also called "options." @author Apache Directory Project
