Method Detail

convert

public static java.sql.ResultSet convert(ActivityOutput output)
                                  throws NoActivityOutputException,
                                         DataFormatException

Converts an activity output to a forward-only java.sql.ResultSet. The activity output must be an XML WebRowSet representation of a relational database query result.

Parameters:: output - Output with the data to convert
Returns:: forward-only ResultSet representing the query result that is in the give activity output.
Throws:: NoActivityOutputException - if there is no output data or the data has not yet been processed to this output or the activity that generates this output has not yet been executed.; DataFormatException - if the output from the activity cannot be parsed into a ResultSet.

convert

public static java.sql.ResultSet convert(ActivityOutput output,
                                         int resultSetType)
                                  throws NoActivityOutputException,
                                         DataFormatException

Converts an activity output to a java.sql.ResultSet. The activity output must be an XML WebRowSet representation of a relational database query result.

Parameters:: output - Output with the data to convert; resultSetType - One of ResultSet.TYPE_FORWARD_ONLY or ResultSet.TYPE_SCROLL_INSENSITIVE.
Returns:: ResultSet of the requested type representing the query result that is in the give activity output.
Throws:: java.lang.IllegalArgumentException - if resultSetType is not one of the two above.; NoActivityOutputException - if there is no output data or the data has not yet been processed to this output or the activity that generates this output has not yet been executed.; DataFormatException - if the output from the activity cannot be parsed into a ResultSet.

convertFromCSV

public static java.sql.ResultSet convertFromCSV(ActivityOutput output)
                                         throws NoActivityOutputException,
                                                DataFormatException

Converts an activity output to a forward-only java.sql.ResultSet. The activity output must be a CSV representation of a relational database query result. This method assumes default CSV file format (delimiter=, lineBreak=CRLF nullDataStr=NULL).

Parameters:: output - Output with the data to convert
Returns:: forward-only ResultSet representing the query result that is in the give activity output.
Throws:: NoActivityOutputException - if there is no output data or the data has not yet been processed to this output or the activity that generates this output has not yet been executed.; DataFormatException - if the output from the activity cannot be parsed into a ResultSet.

                                         throws NoActivityOutputException,
                                                DataFormatException

Converts an activity output to a java.sql.ResultSet. The activity output must be a CSV representation of a database query result. This method assumes default CSV file format (delimiter=, lineBreak=CRLF nullDataStr=NULL).

Parameters:: output - Output with the data to convert; resultSetType - One of ResultSet.TYPE_FORWARD_ONLY or ResultSet.TYPE_SCROLL_INSENSITIVE.
Returns:: ResultSet of the requested type representing the query result that is in the give activity output.
Throws:: java.lang.IllegalArgumentException - if resultSetType is not one of the two above.; NoActivityOutputException - if there is no output data or the data has not yet been processed to this output or the activity that generates this output has not yet been executed.; DataFormatException - if the output from the activity cannot be parsed into a ResultSet.
