Method Detail

end

public void end()

No-op

Specified by:

end in interface Transaction

startExitCall

public ExitCall startExitCall(java.lang.String uniquePropertiesIdentifier,
                              java.lang.String displayName,
                              java.lang.String exitType,
                              boolean async)

Returns a NoOpExitCall object

Specified by:

startExitCall in interface Transaction

Parameters:

uniquePropertiesIdentifier - A String unique to this exit call (can be the same between requests)

displayName - The display name of exit call

exitType - Specifies the exit type. If this is null, then it is treated as a custom exit. For supported types, refer ExitTypes. For example, HTTP.

async - Specifies if the exit call is asynchronous

Returns:

a NoOpExitCall object

startExitCall

public ExitCall startExitCall(java.util.Map<java.lang.String,java.lang.String> uniquePropertiesIdentifier,
                              java.lang.String displayName,
                              java.lang.String exitType,
                              boolean async)

Returns a NoOpExitCall object

Specified by:

startExitCall in interface Transaction

Parameters:

uniquePropertiesIdentifier - A map of key/value pairs used to aggregate exit calls together to the same place

displayName - The display name of exit call

exitType - Specifies the exit type. If this is null, then it is treated as a custom exit. For supported types, refer ExitTypes. For example, HTTP.

async - Specifies if the exit call is asynchronous

Returns:

a NoOpExitCall object

startHttpExitCall

public ExitCall startHttpExitCall(java.util.Map<java.lang.String,java.lang.String> uniquePropertiesIdentifier,
                                  java.net.URL url,
                                  boolean async)

Description copied from interface: Transaction

Declares the start of an http exit call. Add this call in a place where control is leaving the current process, either in a synchronous or asynchronous fashion.

Note: This returns a no-op IExitCall if called when an exit call already exists, or if it is otherwise unable to start a new exit call.

Specified by:

startHttpExitCall in interface Transaction

Parameters:

uniquePropertiesIdentifier - A map of key/value pairs used to aggregate exit calls together to the same place

url - The url of the exit

async - Specifies if the exit call is asynchronous

Returns:

an ExitCall object to represent the exit call

markHandoff

public void markHandoff(java.lang.Object commonObject)

No-op

Specified by:

markHandoff in interface Transaction

Parameters:

commonObject - A unique common object to link the start and execution of the asynchronous handoff.

markAsError

public void markAsError(java.lang.String errorMessage)

No-op

Specified by:

markAsError in interface Transaction

Parameters:

errorMessage - The message to associate with the error object created.
