Class FastpathArg

java.lang.Object
org.postgresql.fastpath.FastpathArg
Direct Known Subclasses:
FastpathArg.ByteStreamWriterFastpathArg
@Deprecated public class FastpathArg extends 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.
