Encapsulates the metadata of JCo data containers. Each element of metadata describes a field of these data containers in terms of name, type, length, etc. JCoMetadata is the basis for the two important metadata interfaces of JCo, and includes their common functionality: JCoListMetaData and JCoRecordMetaData. <br> Moreover, it contains constants for all supported data types, where each JCo data type corresponds to one of the builtin types of ABAP.
