bool	get_verbose_mode () const
	Get status of verbose mode. The method returns true, if the verbose mode is switched 'On'.
void	set_verbose_mode (const bool b)
	Set status of verbose mode. To switch 'On'/'Off' use the method's parameter:
bool	get_silence_mode () const
	Get status of silence mode. The method returns true, if the silence mode is switched 'On'. In such case the OKS will not print any info, warnings and error messages.
void	set_silence_mode (const bool b)
	Set status of silence mode. To switch 'On'/'Off' use the method's parameter:
bool	get_profiling_mode () const
	Get status of profiling mode. The method returns true, if the profiling mode is switched 'On'. In such case the OKS will report time spend to execute main methods and a summary table of their calls on the OKS kernel destroy.

Detailed Description

Provides interface to the OKS kernel.

It is responsible for loading OKS data and schema files and it provides access to loaded OKS classes and their objects.

To work with OKS schema the following base methods are available:

• load_schema() - load OKS schema from file (i.e. read description of classes with attributes, relationships and methods)
• new_schema() - create new OKS schema file
• set_active_schema() - use this schema file for newly created classes
• save_schema() - save OKS schema file
• close_schema() - close OKS schema file and unload all classes from it
• classes() - get list of OKS classes
• find_class() - get class by name

To work with OKS data the following base methods are available:

• load_data() - load OKS data from file (i.e. read description of OKS objects)
• reload_data() - reload data file, e.g. to revert to saved data or when it was modified by external process
• new_data() - create new OKS data file
• set_active_data() - use this data file for newly created classes
• save_data() - save OKS data file
• close_data() - close OKS data file and unload all objects from it
• objects() - get all objects (unsorted by classes or IDs)

To work with OKS server the following methods can be used:

• commit_repository() - commit changes from user repository files on the OKS server
• update_repository() - update files on user repository from OKS server

When schema or data are modified, the process can give callback using the following methods:

• subscribe_create_class() - notify, when new class is created
• subscribe_change_class() - notify, when existing class is modified
• subscribe_delete_class() - notify, when existing class is removed
• subscribe_create_object() - notify, when new object is created
• subscribe_change_object() - notify, when existing object is modified
• subscribe_delete_object() - notify, when existing object is removed

When objects are created in unordered manner or by efficiency reasons files are loaded with non-bind option, the objects can be bind (i.e. linked) using the following methods:

• bind_objects() - link relationships of existing objects
• get_bind_objects_status() - get status of last bind_objects() operation

In case of problems most of above methods throw exceptions derived from oks::exception class.

Most of the OksKernel methods are thread-safe. Those which are not thread-safe, are started from prefix "k_".

close_data()

void dunedaq::oks::OksKernel::close_data	(	OksFile *	file_h,
		bool	unbind_objects = true )

Close OKS data file.

The method closes given OKS data file. All objects belonging to this data file will be destroyed in-memory. The relationships values of objects from others data files loaded in-memory will be converted from OksObject pointer to UID for all objects of closing data file, if the unbind_objects parameter is true. If it is necessary to close all loaded data files, it is recommended to use close_all_data() method and do not use close_data(..., true) method sequentially by performance reasons.

The method is thread-safe. The user must not have the OKS kernel lock set in the thread which calls this method.

Parameters

file_h	a pointer to the OKS schema file descriptor returned by a kernel method
unbind_objects	convert values of relationships pointing to objects of closing data file from OksObject pointer to the UID

load_data()

OksFile * dunedaq::oks::OksKernel::load_data	(	const std::string &	name,
		bool	bind = true )

Load OKS data file.

The method loads OKS data file.

The method is thread-safe. The user must not have the OKS kernel lock set in the thread which calls this method.

By default, after the the data file is loaded, the kernel tries to resolve links between objects. This can be rather cpu consuming operation and it is not scalable for sequential load of many files. In this case it is recommended to change the default bind parameter to false for all but last loading data file.

Parameters

name	name of the file to be loaded
bind	if true (by default), resolve links between objects

Returns

Return pointer to the OKS file descriptor.

Exceptions

Throw

oks::exception in case of problems.

load_file()

OksFile * dunedaq::oks::OksKernel::load_file	(	const std::string &	name,
		bool	bind = true )

Load OKS database file.

The method loads OKS schema or data xml file. It parses the file's xml header to detect the file type and calls appropriate load_schema() or load_data() method.

The method is thread-safe. The user may not have the OKS kernel lock set in the thread which calls this method.

The parameters of the method are:

reload_data()

void dunedaq::oks::OksKernel::reload_data	(	std::set< OksFile * > &	files,
		bool	allow_schema_extension = true )

Reload OKS data files.

The method reloads data files. The non-modified objects are not changed in-memory. The objects which were removed in the file are removed in-memory. New objects created in the file are created in-memory. The values of an object' relationships and attributes changed in the file are changed in memory, the address of such object in-memory is not changed.

The method is thread-safe. The user must not have the OKS kernel lock set in the thread which calls this method.

The method invokes notification on changes if there is an appropriate subscription.

The method parameters are:

Parameters

files	set of pointer to the OKS data file descriptors returned by a kernel method
allow_schema_extension	if true, new schema files can be included in modified data files

Exceptions

Throw

oks::exception in case of problems.
