Detailed Description

template<class ResourceHandle, class ClaimPolicy = DontClaimResources>
class hardware_interface::HardwareResourceManager< ResourceHandle, ClaimPolicy >

Base class for handling hardware resources.

Hardware resources are encapsulated inside handle instances, and this class allows to register and get them by name. It is also possible to specify through the ClaimPolicy template parameter whether getting a handle claims the corresponding resource or not, like in the following example

// If unspecified, the resource manager will not claim resources
{
HardwareResourceManager<JointStateHandle> m;
// Populate m
m.getHandle("handle_name"); // DOES NOT claim the "handle_name" resource
}
// Explicitly set ClaimPolicy to DontClaimResources
{
HardwareResourceManager<JointStateHandle, DontClaimResources> m;
// Populate m
m.getHandle("handle_name"); // DOES NOT claim the "handle_name" resource
}
// Explicitly set ClaimPolicy to ClaimResources
{
HardwareResourceManager<JointHandle, ClaimResources> m;
// Populate m
m.getHandle("handle_name"); // DOES claim the "handle_name" resource
}
Template Parameters
ResourceHandleResource handle type. The only requisite on the type is that it implements a std::string getName() method.
ClaimPolicySpecifies the resource claiming policy for resource handling

◆ ResourceHandleType

template<class ResourceHandle, class ClaimPolicy = DontClaimResources>
typedef ResourceHandle hardware_interface::HardwareResourceManager< ResourceHandle, ClaimPolicy >::ResourceHandleType

Member Function Documentation

◆ getHandle()

template<class ResourceHandle, class ClaimPolicy = DontClaimResources>
ResourceHandle hardware_interface::HardwareResourceManager< ResourceHandle, ClaimPolicy >::getHandle ( const std::string &  name)
inline

Get a resource handle by name.

Note
If the ClaimPolicy template parameter is set to ClaimResources, calling this method will internally claim the resource. If set to DontClaimResources, calling this method will not claim the resource.
Parameters
nameResource name.
Returns
Resource associated to name. If the resource name is not found, an exception is thrown.
