bool | ready () const |
Returns true when all methods were resolved. | |
void | disconnect () |

Public Attributes | |
OperationCaller< bool(const std::string &filename)> | loadProperties |
Read a property file and update (or create any missing) properties in the TaskContext. | |

bool RTT::ServiceRequester::connectTo | ( | Service::shared_ptr | sp | ) | [inherited] |
Connects this service's methods to the operations provided by op.
This method tries to match as many as possible method-operation pairs.
You may call this function with different instances of sp to 'resolve' missing functions, only the non-connected methods will be further filled in.
sp | An interface-compatible Service. |

Service::shared_ptr RTT::ServiceRequester::getReferencedService | ( | ) | [inherited] |
Returns the service we're referencing.
In case you used connectTo to more than one service, this returns the service which was used when connectTo first returned true.
bool RTT::ServiceRequester::ready | ( | ) | const [inherited] |
Returns true when all methods were resolved.

OperationCaller<bool (const std::string& filename)> RTT::Marshalling::loadProperties |
Read a property file and update (or create any missing) properties in the TaskContext.
This function allows to dynamically add properties to a component. This can be useful in combination with Orocos scripts when the script requires additional properties from the parent TaskContext.

OperationCaller<bool (const std::string& filename)> RTT::Marshalling::readProperties |
Read the property file and 'refresh' all the properties of the TaskContext.
There may be more properties in the file than properties in the TaskContext, but all properties of the TaskContext must be present in filename. In case a type mismatch occurs, this method will fail and update no properties.
filename | The file to read from. |

OperationCaller<bool (const std::string& name,const std::string& filename)> RTT::Marshalling::readProperty |
Read a single property from a file.
The name may be a 'path' like location of a Property in the hierarchy.
name | The name of the property in the file. For example "MyProp" for a top-level property or "Settings.XML.Editor" to specify a dot-separated 'path' to the property 'Editor'. |
filename | The name of the file in which to lookup name. |

OperationCaller<bool (const std::string& filename)> RTT::Marshalling::storeProperties |
Stores all properties of parent TaskContext 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.
filename | The file to store to. |

OperationCaller<bool (const std::string& filename)> RTT::Marshalling::updateFile |
Write the property file with the properties of a TaskContext, which are already present in filename.
No new entries are created in the file, only existing ones are updated. The file is first read in, the resulting tree is updated with the task's properties, and then written to disk again.
filename | The file to read from and write to. |

OperationCaller<bool (const std::string& filename)> RTT::Marshalling::updateProperties |
Read the property file and 'refresh' some properties of the TaskContext.
There may be more properties in the file than properties in the TaskContext, and some may be missing in the file. This method will update 'as much as possible' properties. In case a type mismatch occurs, this method will fail and update no properties.
filename | The file to read all the properties from. |
Definition at line 102 of file Marshalling.hpp.

OperationCaller<bool (const std::string& filename)> RTT::Marshalling::writeProperties |
Write the property file with the properties of a TaskContext.
The file is first read in, the resulting tree is updated with the task's properties and then written to disk again. This allows to share files between tasks.
filename | The file to read from and write to (updating). |

OperationCaller<bool (const std::string& name, const std::string& filename)> RTT::Marshalling::writeProperty |
Write a single property to a file.
The name may be a 'path' like location of a Property in the hierarchy.
name | The name of the property in the file. For example "MyProp" for a top-level property or "Settings.XML.Editor" to specify a dot-separated 'path' to the property 'Editor'. |
