Wrapper for the diagnostic_msgs::DiagnosticStatus message that makes it easier to update.
This class handles common string formatting and vector handling issues for filling the diagnostic_msgs::DiagnosticStatus message. It is a subclass of diagnostic_msgs::DiagnosticStatus, so it can be passed directly to diagnostic publish calls.

| void diagnostic_updater::DiagnosticStatusWrapper::add | ( | const std::string & | key, |
| const T & | val | ||
| ) | [inline] |
Add a key-value pair.
This method adds a key-value pair. Any type that has a << stream operator can be passed as the second argument. Formatting is done using a std::stringstream.
| key | Key to be added. |
| value | Value to be added. |

| void diagnostic_updater::DiagnosticStatusWrapper::add | ( | const std::string & | key, |
| const bool & | b | ||
| ) | [inline] |
For bool, diagnostic value is "True" or "False".

| void diagnostic_updater::DiagnosticStatusWrapper::addf | ( | const std::string & | key, |
| const char * | format, | ||
| ... | |||
| ) | [inline] |
Add a key-value pair using a format string.
This method adds a key-value pair. A format string is used to set the value. The current implementation limits the value to 1000 characters in length.

| void diagnostic_updater::DiagnosticStatusWrapper::clear | ( | ) | [inline] |
Clear the key-value pairs.
The values vector containing the key-value pairs is cleared.

| void diagnostic_updater::DiagnosticStatusWrapper::clearSummary | ( | ) | [inline] |
clears the summary, setting the level to zero and the message to "".

| void diagnostic_updater::DiagnosticStatusWrapper::mergeSummary | ( | unsigned char | lvl, |
| const std::string | s | ||
| ) | [inline] |
Merges a level and message with the existing ones.
It is sometimes useful to merge two DiagnosticStatus messages. In that case, the key value pairs can be unioned, but the level and summary message have to be merged more intelligently. This function does the merge in an intelligent manner, combining the summary in *this, with the one that is passed in.
The combined level is the greater of the two levels to be merged. If both levels are non-zero (not OK), the messages are combined with a semicolon separator. If only one level is zero, and the other is non-zero, the message for the zero level is discarded. If both are zero, the new message is ignored.
| lvl | Numerical level to of the merged-in summary. |
| s | Descriptive status message for the merged-in summary. |

| void diagnostic_updater::DiagnosticStatusWrapper::mergeSummary | ( | const diagnostic_msgs::DiagnosticStatus & | src | ) | [inline] |
Version of mergeSummary that merges in the summary from another DiagnosticStatus.
| src | DiagnosticStatus from which to merge the summary. |

| void diagnostic_updater::DiagnosticStatusWrapper::mergeSummaryf | ( | unsigned char | lvl, |
| const char * | format, | ||
| ... | |||
| ) | [inline] |
Formatted version of mergeSummary.
This method is identical to mergeSummary, except that the message is an sprintf-style format string.
| lvl | Numerical level to of the merged-in summary. |
| format | Format string for the descriptive status message for the merged-in summary. |
| ... | Values to be formatted by the format string. |

| void diagnostic_updater::DiagnosticStatusWrapper::summary | ( | unsigned char | lvl, |
| const std::string | s | ||
| ) | [inline] |
Fills out the level and message fields of the DiagnosticStatus.
| lvl | Numerical level to assign to this Status (OK, Warn, Err). |
| s | Descriptive status message. |

| void diagnostic_updater::DiagnosticStatusWrapper::summary | ( | const diagnostic_msgs::DiagnosticStatus & | src | ) | [inline] |
copies the summary from a DiagnosticStatus message
| src | StatusWrapper to copy the summary from. |
