Constructor & Destructor Documentation

madara::knowledge::WaitSettings::WaitSettings ( )

inline

Constructor.

Definition at line 42 of file WaitSettings.h.

madara::knowledge::WaitSettings::WaitSettings	(	bool	t_delay_sending_modifieds,
		bool	t_treat_globals_as_locals,
		bool	t_signal_updates,
		bool	t_always_overwrite,
		bool	t_always_expand,
		bool	t_track_local_changes,

		uint64_t	t_clock_increment = `1`,
		bool	t_treat_locals_as_globals = `false`
	)

inline

Constructor.

Parameters

t_delay_sending_modifieds	true to send modifieds
t_treat_globals_as_locals	true if global variables should be marked as not to be sent to the transport
t_signal_updates	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_pre_print_statement	statement to print out before evaluations
t_post_print_statement	statement to print out after evaluations
t_poll_frequency	the frequency to poll for changes (in seconds)
t_max_wait_time	the maximum time to wait for truth (in seconds)
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).

Definition at line 124 of file KnowledgeUpdateSettings.h.

uint64_t madara::knowledge::KnowledgeUpdateSettings::clock_increment

inherited

Default clock increment.

Definition at line 136 of file KnowledgeUpdateSettings.h.

const WaitSettings madara::knowledge::WaitSettings::DEFAULT

static

Settings to immediately send modifieds, but do expand variables.

Definition at line 28 of file WaitSettings.h.

const WaitSettings madara::knowledge::WaitSettings::DELAY

static

Settings to delay sending modifieds, but do expand variables.

Definition at line 34 of file WaitSettings.h.

const WaitSettings madara::knowledge::WaitSettings::DELAY_NO_EXPAND

static

Settings to delay sending modifieds, and not expand variables.

Definition at line 37 of file WaitSettings.h.

bool madara::knowledge::EvalSettings::delay_sending_modifieds

inherited

Toggle for sending modifieds in a single update event after each evaluation.

Definition at line 114 of file EvalSettings.h.

bool madara::knowledge::KnowledgeReferenceSettings::expand_variables

inherited

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

Definition at line 65 of file KnowledgeReferenceSettings.h.

const KnowledgeUpdateSettings madara::knowledge::KnowledgeUpdateSettings::GLOBAL_AS_LOCAL

staticinherited

Definition at line 30 of file KnowledgeUpdateSettings.h.

const KnowledgeUpdateSettings madara::knowledge::KnowledgeUpdateSettings::GLOBAL_AS_LOCAL_NO_EXPAND

staticinherited

Definition at line 31 of file KnowledgeUpdateSettings.h.

double madara::knowledge::WaitSettings::max_wait_time

Maximum time to wait for an expression to become true (in seconds)

Definition at line 113 of file WaitSettings.h.

bool madara::knowledge::KnowledgeReferenceSettings::never_exit

inherited

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

Definition at line 70 of file KnowledgeReferenceSettings.h.

const WaitSettings madara::knowledge::WaitSettings::NO_EXPAND

static

Settings to immediately send modifieds, and not expand variables.

Definition at line 31 of file WaitSettings.h.

double madara::knowledge::WaitSettings::poll_frequency

Frequency to poll an expression for truth (in seconds)

Definition at line 108 of file WaitSettings.h.

std::string madara::knowledge::EvalSettings::post_print_statement

inherited

Statement to print after evaluations.

Definition at line 124 of file EvalSettings.h.

std::string madara::knowledge::EvalSettings::pre_print_statement

inherited

Statement to print before evaluations.

Definition at line 119 of file EvalSettings.h.

std::map<std::string, bool> madara::knowledge::EvalSettings::send_list

inherited

Map of record names that are allowed to be sent after operation.

The map is only valid if

See also: delay_sending_modifieds is false.

Definition at line 130 of file EvalSettings.h.

bool madara::knowledge::KnowledgeUpdateSettings::signal_changes

inherited

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

inherited

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

inherited

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

inherited

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
