Method Details

readAny

public QueryExecResult readAny(InputStream in,
 Context context)

Description copied from interface: RowSetReader

Read from an InputStream and produce a QueryExecResult. Note that return result may stream and so the input stream may be read while the RowSet is used. See RowSetReader.read(InputStream, Context) for more details

Specified by:

readAny in interface RowSetReader

Parameters:

in - InputStream to read from.

Returns:

QueryExecResult

process

public static QueryExecResult process(InputStream in,
 Context context)

createRowSet

public static RowSetBuffered<RowSetJSONStreaming<?>> createRowSet(InputStream in,
 Context context)

configureValidationFromContext

public static ValidationSettings configureValidationFromContext(ValidationSettings settings,
 Context cxt)

Apply settings present in the context to a given ValidationSettings instance
