uDARemoteDataAdapterRequests

TDAGetSchemaRequest = class(TDARemoteDataAdapterRequest);

Property	Type	Description
IncomingSchemaParameter	String	Specifies the parameter that will contain the data received from the server. This parameter must be configured for all schema request calls as it will be used to obtain the actual schema information sent form the server. Depending on the used Data Streamer and server interface, this can be a Binary or String type; the legacy v3.0 server interface uses the data streamer to encode schema information, while the v4.0 interface will return the original XML schema.
OutgoingFilterParameter	String	Defines a string parameter that can be used to transmit an optional filter string to the server, to limit the scope of the retrieved schema. This filter value is not used by the default service implementations, but can be evaluated by custom code (for example in the OnGetSchemaAsXMLEvent event) to restrict or modify the returned schema.
