Constructor & Destructor Documentation

madara::knowledge::KnowledgeUpdateSettings::KnowledgeUpdateSettings ( )

inline

Constructor.

Definition at line 36 of file KnowledgeUpdateSettings.h.

madara::knowledge::KnowledgeUpdateSettings::KnowledgeUpdateSettings	(	bool	t_treat_globals_as_locals,
		bool	t_signal_changes = `true`,
		bool	t_always_overwrite = `false`,
		bool	t_always_expand = `true`,
		bool	t_track_local_changes = `true`,
		uint64_t	t_clock_increment = `1`,
		bool	t_treat_locals_as_globals = `false`
	)

inline

Constructor.

Parameters

t_treat_globals_as_locals	true if global variables should be marked as not to be sent to the transport
t_signal_changes	indicates whether to signal updates to a separate thread that may be waiting. This is only potentially useful to multithreaded MADARA apps
t_always_overwrite	always overwrite, despite quality
t_always_expand	always try to expand variable names
t_track_local_changes	if true, keep track of modifications to local variables for checkpoint saving purposes.
t_clock_increment	amount of clock ticks to increment updated records by
t_treat_locals_as_globals	true if local variable changes should be sent over the network (dangerous).

bool madara::knowledge::KnowledgeUpdateSettings::always_overwrite

Toggle for always overwriting records, regardless of quality, clock values, etc.

Definition at line 124 of file KnowledgeUpdateSettings.h.

uint64_t madara::knowledge::KnowledgeUpdateSettings::clock_increment

Default clock increment.

bool madara::knowledge::KnowledgeReferenceSettings::expand_variables

Toggle for always attempting to expand variables (true) or never expanding variables (false)

bool madara::knowledge::KnowledgeReferenceSettings::never_exit

inherited

Never allow MADARA to exit, even with fatal errors or invalid state.

Definition at line 29 of file KnowledgeUpdateSettings.h.

bool madara::knowledge::KnowledgeUpdateSettings::signal_changes

Toggle whether to signal changes have happened.

Setting this to false will increase performance, but in general should be left to true. Setting this to false can result in problems with wait statements.

Definition at line 118 of file KnowledgeUpdateSettings.h.

bool madara::knowledge::KnowledgeUpdateSettings::track_local_changes

Toggle for checkpointing support.

If this is true, all changes will be added to the local changes map in the knowledge base, which is used by save_checkpoint to create diffs of knowledge

Definition at line 131 of file KnowledgeUpdateSettings.h.

bool madara::knowledge::KnowledgeUpdateSettings::treat_globals_as_locals

Toggle whether updates to global variables are treated as local variables and not marked as modified to the transport.

Definition at line 110 of file KnowledgeUpdateSettings.h.

bool madara::knowledge::KnowledgeUpdateSettings::treat_locals_as_globals

Toggle whether updates to local variables are treated as global variables that should be sent over the transport.

It should be stressed that this is dangerous and should only be used for debugging. If you toggle this to true, all local variables will be sent over the network where they will overwrite local variables in remote systems, unless the remote system filters out the local variable changes with an on-receive filter
