Member Function Documentation

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
filenameThe file to read from.
allConfigure 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::configure ( const std::string &  filename,
const std::string &  name 
) const

Read a single property from a file.

Parameters
filenameThe file to read from.
nameThe 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 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
filenameThe 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.

Definition at line 64 of file PropertyLoader.cpp.

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
filenameThe file to read from and write to (updating).
allWrite 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::save ( const std::string &  filename,
const std::string &  name 
) const

Write a single property to a file, or update an existing file.

Parameters
filenameThe file to update or write to.
nameThe 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 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
filenameThe 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.
