Method Detail

connect

void connect()
             throws Exception

Make the connection to the underlying transport. The fact that this object is connected or not should have no influence on the lifecycle, especially the start / stop state if applicable.

Throws:

Exception

disconnect

void disconnect()
                throws Exception

Disconnect the from the underlying transport

Throws:

Exception

isConnected

boolean isConnected()

Determines if this object is connected or not

getConnectionDescription

String getConnectionDescription()

Returns a string identifying the underlying resource

validateConnection

RetryContext validateConnection(RetryContext retryContext)

Test whether the connector is able to connect to its resource(s). This will allow a retry policy to go into effect in the case of failure. Implementations must call either:

• RetryContext.setOk() when no problems found (or no validation required).
• RetryContext.setFailed(Throwable) with a root cause for a connection failure.

Callers should then check for RetryContext.isOk(). The failure, if any, will be provided via the RetryContext.getLastFailure().

Returns:

same retry context with status info set and any failures populated

Throws:

Exception - if the connector fails to connect @param retryContext
