hashCode in class Object

captureStack

public final void captureStack(long leakDetectionThreshold,
                Timer scheduler)

Catpure the stack and start leak detection.

Specified by:

captureStack in interface IHikariConnectionProxy

Parameters:

leakDetectionThreshold - the number of milliseconds before a leak is reported

scheduler - the timer to run the leak detection task with

checkException

public final void checkException(SQLException sqle)

Check if the provided SQLException contains a SQLSTATE that indicates a disconnection from the server.

Specified by:

checkException in interface IHikariConnectionProxy

Parameters:

sqle - the SQLException to check

getExpirationTime

public final long getExpirationTime()

Get the expiration timestamp of the connection.

Specified by:

getExpirationTime in interface IHikariConnectionProxy

Returns:

the expiration timestamp, or Long.MAX_VALUE if there is no maximum lifetime

getLastAccess

Specified by:

getLastOpenTime in interface IHikariConnectionProxy

Returns:

the timestamp the connection started to be used in the most recent request

isBrokenConnection
