ValueParser(TaskContext *tc, CommonParser &cp)
Definition: ValueParser.cpp:48
void clear()
Clears this parser, not the repository where it stores its results.
This class contains some very common parser definitions.
A class for parsing const values.
Definition: ValueParser.hpp:58
Get the peer and object from an invocation path like a.b.c.d() .
Definition: PeerParser.hpp:58
rule< scanner_t > rule_t
Get the property and bag from an invocation path like bag.subbag.prop .
The TaskContext is the C++ representation of an Orocos component.
Definition: TaskContext.hpp:93
boost::intrusive_ptr< DataSourceBase > shared_ptr
Use this type to store a pointer to a DataSourceBase.
Contains TaskContext, Activity, OperationCaller, Operation, Property, InputPort, OutputPort, Attribute.
Definition: Activity.cpp:51
