Class FastpathArg

java.lang.Object

org.postgresql.fastpath.FastpathArg

@Deprecated
public class FastpathArg
extends java.lang.Object

Deprecated.

This API is somewhat obsolete, as one may achieve similar performance and greater functionality by setting up a prepared statement to define the function call. Then, executing the statement with binary transmission of parameters and results substitutes for a fast-path function call.

Each fastpath call requires an array of arguments, the number and type dependent on the function being called.
