Constructor.
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). |
t_stream_changes | true if changes must be streamed |
t_exceptions_on_unitialized | true if exceptions must be thrown when reading uninitialized variables |

bool madara::knowledge::KnowledgeUpdateSettings::signal_changes = true |
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 108 of file KnowledgeUpdateSettings.h.
bool madara::knowledge::KnowledgeUpdateSettings::stream_changes = true |
Toggle for streaming support.
If this is true, all changes will be streamed to the attached streamer, if any.
Definition at line 144 of file KnowledgeUpdateSettings.h.
bool madara::knowledge::KnowledgeUpdateSettings::track_local_changes = true |
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

bool madara::knowledge::KnowledgeUpdateSettings::treat_globals_as_locals = false |
Toggle whether updates to global variables are treated as local variables and not marked as modified to the transport.
Definition at line 100 of file KnowledgeUpdateSettings.h.
bool madara::knowledge::KnowledgeUpdateSettings::treat_locals_as_globals = false |
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
