Interface StreamResults

All Superinterfaces:

AutoCloseable, Closeable, Serializable

public interface StreamResults
extends Serializable, Closeable

Unifying (and very limited) JDBC ResultSet like API to a forward-only cursor on a query result, either from a Hibernate or PA query.

Method Summary

Modifier and Type	Method and Description
void	close() Releases the often significant resources required to provide access to the query result set.
Object	get() Retrieves the current row, which depending on the query executed could be anything from a PersistedObject to a map of (field,value) pairs to a single primitive value.
boolean	next() Moves the cursor forward one row from its current position.

Method Detail

next

boolean next()

Moves the cursor forward one row from its current position. A cursor is initially positioned before the first row; the first call to the method next makes the first row the current row; the second call makes the second row the current row, and so on.

Returns:

true if the new current row is valid; false if there are no more rows.

get

Object get()

Retrieves the current row, which depending on the query executed could be anything from a PersistedObject to a map of (field,value) pairs to a single primitive value.

close

void close()

Releases the often significant resources required to provide access to the query result set. If not closed this could lead to memory leaks, and ultimately system instability or even a system crash.
