All Implemented Interfaces:

ProResultSetMetaData, java.sql.ResultSetMetaData, java.io.Serializable

public class ProResultSetMetaDataImpl

extends com.progress.open4gl.dynamicapi.ResultSetMetaData

The ProResultSetMetaDataImpl class is used by the the application to set metadata for an Input Temp-Table that maps to a 4GL TABLE-HANDLE parameter. Because the 4GL temp-table is dynamic, the proxy does not know what its schema is. Thus the application must provide it itself via this class.
