Class SQLInputFromChunk

java.lang.Object
  org.postgresql.pljava.jdbc.SQLInputFromChunk

All Implemented Interfaces:

SQLInput

public class SQLInputFromChunk
extends Object
implements SQLInput

The SQLInputToChunk uses JNI to read from memory that has been allocated by the PostgreSQL backend. A user should never make an attempt to create an instance of this class. Only internal JNI routines can do that. An instance is propagated in a call from the internal JNI layer to the Java layer will only survive during that single call. The handle of the instance will be invalidated when the call returns and subsequent use of the instance will yield a SQLException with the message "Stream is closed".
