Method Detail

getImmutableActivityContext

Map<String,String> getImmutableActivityContext(ActivityHandle activityHandle)
                                        throws UnrecognizedActivityHandleException

Gets an immutable copy of the activity’s logging context.

Intended for use when calling up from the network, to fetch the existing state of an activity, once the activity is known.

Parameters:

activityHandle - Activity handle for the activity to get the Logging context for.

Returns:

Map<String, String> context

Throws:

UnrecognizedActivityHandleException

Since:

Rhino 2.6.0

getImmutableThreadContext

Map<String,String> getImmutableThreadContext()

Gets an immutable copy of the current thread’s logging context.

Intended for use by components with internal thread pools, to manage moving a logging context between an RA internal thread, and an activity plus rhino thread.

Returns:

Map<String, String> context

Since:

Rhino 2.6.0

clearThreadContext

void clearThreadContext()

Clears the current thread’s logging context.

Provided for use by components with internal thread pools, to remove the logging context from an RA internal thread when the thread has completed work associated with an activity.

Since:

Rhino 2.6.0

put

void put(String key,
         String value)

Add a single key/value pair to the current thread’s logging context. This does not modify the logging context of any activities directly. Provided for use by RAs before an activity has been started/located, for example in a network IO thread.

Parameters:

key - String context key to add to the thread’s logging context

value - String context value to add to the thread’s logging context

Since:

Rhino 2.6.0

putAll

void putAll(Map<String,String> entries)

Add a map of key/value pairs to the current thread’s logging context. This does not modify the logging context of any activities directly. Provided for use by RAs before an activity has been started/located, for example in a network IO thread.

Parameters:

entries - Map of key, value pairs to add to the thread’s logging context

Since:

Rhino 2.6.0

remove

void remove(String key)

Remove a key from the current thread’s logging context. This does not modify the logging context of any activities directly. Provided for use by RAs before an activity has been started/located, for example in a network IO thread.

Parameters:

key - String key to remove from the thread’s logging context

Since:

Rhino 2.6.0

put

void put(ActivityHandle activityHandle,
         String key,
         String value)
  throws UnrecognizedActivityHandleException

Add a key value pair to this activity’s logging context. It will be logged in all subsequent log statements for this activity.

Care must be taken to not overload the context with too many entries.

Parameters:

key - String key to add.

value - String value to add.

Throws:

UnrecognizedActivityHandleException - if the handle is null, or does not point to a live activity

Since:

Rhino 2.6.0

putAll

void putAll(ActivityHandle activityHandle,
            Map<String,String> entries)
     throws UnrecognizedActivityHandleException

Put all context entries into the current logging context. It will be logged in all subsequent log statements for this activity.

Care must be taken to not overload the context with too many entries.

Parameters:

entries - String key and value pairs to add

Throws:

UnrecognizedActivityHandleException - if the handle is null, or does not point to a live activity

Since:

Rhino 2.6.0

remove

void remove(ActivityHandle activityHandle,
            String key)
     throws UnrecognizedActivityHandleException

Remove an entry from the logging context. This entry will not be logged after this call.

Parameters:

key - String key to remove.

Throws:

UnrecognizedActivityHandleException - if the handle is null, or does not point to a live activity

Since:

Rhino 2.6.0
