javax.sql.rowset.serial.SQLOutputImpl — clojure-interop/javax.sql 1.0.0

The output stream for writing the attributes of a custom-mapped user-defined type (UDT) back to the database. The driver uses this interface internally, and its methods are never directly invoked by an application programmer.

When an application calls the method PreparedStatement.setObject, the driver checks to see whether the value to be written is a UDT with a custom mapping. If it is, there will be an entry in a type map containing the Class object for the class that implements SQLData for this UDT. If the value to be written is an instance of SQLData, the driver will create an instance of SQLOutputImpl and pass it to the method SQLData.writeSQL. The method writeSQL in turn calls the appropriate SQLOutputImpl.writeXXX methods to write data from the SQLData object to the SQLOutputImpl output stream as the representation of an SQL user-defined type.

->sql-output-impl clj

(->sql-output-impl attributes map)

Constructor.

Creates a new SQLOutputImpl object initialized with the given vector of attributes and type map. The driver will use the type map to determine which SQLData.writeSQL method to invoke. This method will then call the appropriate SQLOutputImpl writer methods in order and thereby write the attributes to the new output stream.

attributes - a Vector object containing the attributes of the UDT to be mapped to one or more objects in the Java programming language - java.util.Vector<?> map - a java.util.Map object containing zero or more entries, with each entry consisting of 1) a String giving the fully qualified name of a UDT and 2) the Class object for the SQLData implementation that defines how the UDT is to be mapped - java.util.Map<java.lang.String,?>

throws: java.sql.SQLException - if the attributes or the map is a null value
