Detailed Description

A single preprocessor (agent) instance.

Most of the interface of this class is protected and is exposed only to PreprocessorManager (singleton).

This class is NOT thread safe. The caller is responsible of protecting against concurrent access.

Definition at line 38 of file preprocessorinstance.h.

Constructor & Destructor Documentation

PreprocessorInstance()

PreprocessorInstance::PreprocessorInstance ( const QString & id, PreprocessorManager & manager, Tracer & tracer )

protected

Create an instance of a PreprocessorInstance descriptor.

Definition at line 29 of file preprocessorinstance.cpp.

~PreprocessorInstance()

PreprocessorInstance::~PreprocessorInstance ( )

overridedefault

Destroy this instance of the PreprocessorInstance descriptor.

Member Function Documentation

abortProcessing()

bool PreprocessorInstance::abortProcessing ( )

protected

Attempts to abort the processing of the current item.

May be called only if isBusy() returns true and an assertion will remind you of that. Returns true if the abort request was successfully sent (but not necessarily handled by the slave) and false if the request couldn't be sent for some reason.

Definition at line 133 of file preprocessorinstance.cpp.

currentProcessingTime()

qint64 PreprocessorInstance::currentProcessingTime ( )

protected

Returns the time in seconds elapsed since the current item was submitted to the slave preprocessor instance.

If no item is currently being processed then this function returns -1;

Definition at line 124 of file preprocessorinstance.cpp.

enqueueItem()

void PreprocessorInstance::enqueueItem ( qint64 itemId )

protected

This is called by PreprocessorManager to enqueue a PimItem for processing by this preprocessor instance.

Definition at line 63 of file preprocessorinstance.cpp.

id()

const QString & Akonadi::Server::PreprocessorInstance::id ( ) const

inlineprotected

Returns the id of this preprocessor.

This is actually the AgentInstance identifier but it's not a requirement.

Definition at line 125 of file preprocessorinstance.h.

init()

bool PreprocessorInstance::init ( )

protected

This is called by PreprocessorManager just after the construction in order to connect to the preprocessor instance via D-Bus.

In case of failure this object should be destroyed as it can't operate properly. The error message is printed via Tracer.

Definition at line 39 of file preprocessorinstance.cpp.

invokeRestart()

bool PreprocessorInstance::invokeRestart ( )

protected

Attempts to invoke the preprocessor slave restart via AgentManager.

This is the "last resort" action before starting to ignore the preprocessor (after it misbehaved).

Definition at line 153 of file preprocessorinstance.cpp.

isBusy()

bool Akonadi::Server::PreprocessorInstance::isBusy ( ) const

inlineprotected

Returns true if this preprocessor instance is currently processing an item.

That is: if we have called "processItem()" on it and it hasn't emitted itemProcessed() yet.

Definition at line 109 of file preprocessorinstance.h.

itemQueue()

std::deque< qint64 > * Akonadi::Server::PreprocessorInstance::itemQueue ( )

inlineprotected

Returns a pointer to the internal preprocessor instance item queue.

Don't mess with it unless you really know what you're doing. Use enqueueItem() to add an item to the queue. This method is provided to the PreprocessorManager to take over the item queue of a dying preprocessor.

The returned pointer is granted to be non null.
