Detailed Description

Property repository backed by shared memory

Constructor & Destructor Documentation

SharedMemoryPropertyRepository()

lintel::SharedMemoryPropertyRepository::SharedMemoryPropertyRepository	(	const std::shared_ptr< SharedMemoryService > &	sharedMemoryService,
		const std::shared_ptr< SharedMemorySegmentManager > &	sharedMemorySegmentManager,
		const std::shared_ptr< Configuration > &	configuration,
		std::shared_ptr< ProcessName >	processName
	)

Member Function Documentation

allOf()

std::vector< std::shared_ptr< PropertyBase > > lintel::SharedMemoryPropertyRepository::allOf ( const std::string &  processName, const std::string &  className, const std::string &  instanceName, const std::string &  name  )

overridevirtual

Query properties with optional filters

Returns an empty vector by default: an implementation without query support reports "no overrides", which PropertyService reads as "keep the configured default". The default is only reached for FilePropertyRepository, whose values come from the XML configuration and are never queried at runtime.

Parameters

processName	regex for process name
className	regex for class name
instanceName	regex for instance name
name	regex for property name

Reimplemented from lintel::PropertyRepository.

awake()

std::vector< std::shared_ptr< PropertyBase > > lintel::SharedMemoryPropertyRepository::awake ( )

overridevirtual

load all properties from repository and return result

Implements lintel::PropertyRepository.

deleteOf()

void lintel::SharedMemoryPropertyRepository::deleteOf ( const std::vector< std::shared_ptr< PropertyBase > > &  properties )

overridevirtual

deletes properties in the mentioned repository

No-op by default: a read-only repository has nothing to delete from. PropertyService only reaches this method behind an isMutable() check, so the default is unreachable for FilePropertyRepository, which PropertyRepositoryComponent::parse rejects with a ConfigurationException when mutable="true" is configured.

Reimplemented from lintel::PropertyRepository.

getDataStorage()

DataStorage lintel::SharedMemoryPropertyRepository::getDataStorage ( )

overridevirtual

Returns

data storage info

Implements lintel::PropertyRepository.

onAcquireReadLock()

void lintel::SharedMemoryPropertyRepository::onAcquireReadLock ( ) const

inlineoverrideprotectedvirtual

Acquire the shared read lock before serializing the underlying shared memory structure. No-op by default.

Reimplemented from lintel::SharedMemoryRepository.

onMigrate()

void lintel::SharedMemoryPropertyRepository::onMigrate ( int32_t  currentActiveVersion )

overridevirtual

Implements lintel::SharedMemoryRepository.

onReleaseReadLock()

void lintel::SharedMemoryPropertyRepository::onReleaseReadLock ( ) const

inlineoverrideprotectedvirtual

Release the shared read lock after serialization. No-op by default.

Reimplemented from lintel::SharedMemoryRepository.

save() [1/2]

void lintel::SharedMemoryPropertyRepository::save ( const std::vector< std::shared_ptr< PropertyBase > > &  properties )

overridevirtual

save properties to repository

Implements lintel::PropertyRepository.

save() [2/2]

void lintel::SharedMemoryPropertyRepository::save ( std::shared_ptr< PropertyBase >  property )

overridevirtual

save property to repository

Implements lintel::PropertyRepository.
