    • Method Detail

      • getActiveConnections

        int getActiveConnections()
        Get the number of currently active connections in the pool.

        The return value is extremely transient and is a point-in-time measurement. Therefore, due to a time difference between invoking this method and getIdleConnections(), it is possible for the sum of idle plus active connections to be either less than or greater than the value returned by getTotalConnections().

        Returns:
        the current number of active (in-use) connections in the pool

      • getConnectionIdentifier

        ConnectionIdentifier getConnectionIdentifier()
        Get the connection identifier associated with this DataSource.
        Returns:
        the connection identifier

      • getDisplayName

        default String getDisplayName()
        Get a display name for this DataSource.
        Returns:
        a display name for this DataSource

      • getIdleConnections

        int getIdleConnections()
        Get the number of currently idle connections in the pool.

        The return value is extremely transient and is a point-in-time measurement. Therefore, due to a time difference between invoking this method and getActiveConnections(), it is possible for the sum of idle plus active connections to be either less than or greater than the value returned by getTotalConnections().

        Returns:
        the current number of idle connections in the pool

      • getJdbcUrl

        String getJdbcUrl()
        Get the JDBC URL used by this DataSource.
        Returns:
        the JDBC URL

      • getLastAccessTimestamp

        Instant getLastAccessTimestamp()
        Get the timestamp of when the datasource was last accessed.
        Returns:
        the timestamp of when the datasource was last accessed

      • getStartedTimestamp

        Instant getStartedTimestamp()
        Get the timestamp of when the datasource was started.
        Returns:
        the timestamp of when the datasource was started

      • getThreadsAwaitingConnection

        int getThreadsAwaitingConnection()
        Get the number of threads awaiting connections from the pool. The return value is extremely transient and is a point-in-time measurement.
        Returns:
        the number of threads awaiting a connection from the pool

      • getTotalConnections

        int getTotalConnections()
        Get the total number of connections currently in the pool. The return value is transient and is a point-in-time measurement.
        Returns:
        the total number of connections in the pool

      • getUptime

        Duration getUptime()
        Get the duration for which the datasource has been up.
        Returns:
        the duration for which the datasource has been up

      • getDbms

        default Dbms getDbms()
        Gets the dbms type associated with this DataSource.
        Returns:
        the dbms type associated with this DataSource

      • isSystemDb

        default boolean isSystemDb()
        Check if this DataSource is for the system database.
        Returns:
        true if this DataSource is for the system database, false otherwise
