| bool RTT::marsh::PropertyLoader::configure |
( |
const std::string & |
filename, |
|
|
const std::string & |
name | |
|
) |
| | const |
Read a single property from a file.
- Parameters:
-
| filename | The file to read from. |
| name | The path to or name of a property in target. Separate path components with dots. For example, to safe property x: bag_1.bag_2.x |
- Returns:
- true on success, false on error, consult Logger output for messages.
| bool RTT::marsh::PropertyLoader::configure |
( |
const std::string & |
filename, |
|
|
bool |
all = true | |
|
) |
| | const |
Read the XML cpf file and 'refresh' the matching properties of the given Service. There may be more properties in the file than properties in the target.
- Parameters:
-
| filename | The file to read from. |
| all | Configure all properties of target. Return an error if not all properties were found in filename. |
- Returns:
- true on success, false on error, consult Logger output for messages.
- See also:
- save() to create this file.
| bool RTT::marsh::PropertyLoader::load |
( |
const std::string & |
filename |
) |
const |
Read the XML cpf file and create (or refresh the matching properties) of the given Service. Any property in the file which is not in the target, is created in the target.
- Parameters:
-
| filename | The file to read from. |
- Returns:
- true on success, false on error, consult Logger output for messages.
- See also:
- store() for dumping properties in a file.
| bool RTT::marsh::PropertyLoader::save |
( |
const std::string & |
filename, |
|
|
const std::string & |
name | |
|
) |
| | const |
Write a single property to a file, or update an existing file.
- Parameters:
-
| filename | The file to update or write to. |
| name | The path to or name of a property in target. Separate path components with dots. For example, to safe property x: bag_1.bag_2.x |
- Returns:
- true on success, false on error, consult Logger output for messages.
| bool RTT::marsh::PropertyLoader::save |
( |
const std::string & |
filename, |
|
|
bool |
all = true | |
|
) |
| | const |
Write the XML cpf file with the properties of the given Service. The file is first read into memory, the resulting tree is updated with the task's properties and then written to disk again. This allows to share files between tasks.
- Parameters:
-
| filename | The file to read from and write to (updating). |
| all | Write out all properties of target to filename, add missing ones if necessary. |
- Returns:
- true on success, false on error, consult Logger output for messages.
- See also:
- configure() to re-read this file and update matching properties.
| bool RTT::marsh::PropertyLoader::store |
( |
const std::string & |
filename |
) |
const |
Stores all properties of a Service in a new file or overwrite an existing one. The file given in filename will always be overwritten and any existing content will be lost.
- Parameters:
-
| filename | The file to store to. |
- Returns:
- true on success, false on error, consult Logger output for messages.
- See also:
- load() for loading properties in a Service.
