Class PgConnectionCleaningAction

java.lang.Object

org.postgresql.jdbc.PgConnectionCleaningAction

All Implemented Interfaces:

LazyCleaner.CleaningAction<java.io.IOException>

class PgConnectionCleaningAction
extends java.lang.Object
implements LazyCleaner.CleaningAction<java.io.IOException>

This class segregates the minimal resources required for proper cleanup in case the connection has not been closed by the user code.

For now, it has two actions:

• Print stacktrace when the connection has been created, so users can identify the leak
• Release shared timer registration
