Interface Field

All Superinterfaces:

Comparable, Serializable

All Known Implementing Classes:

AbstractField, AccessPathField, DateField, DateFieldImpl, DateRoField, ExplorerField, FileField, GroupField, JdbcField, JdbcRefField, LdapField, MultipleUserField, PdcField, PdcUserField, SequenceField, TextField, TextFieldImpl, TextRoField, UserField

public interface Field
extends Serializable, Comparable

A Field is an item of a DataRecord. The fields of a record may have different types, but they are all managed via this interface. To be displayed in a jsp page a field must be handled by a specific FieldDisplayer which is aware of the internal data type and format of the field. The links between Fields and FieldDisplayers are managed by a RecordTemplate.
