constraint_samplers::UnionConstraintSampler::canService
virtual bool canService(const moveit_msgs::Constraints &constraint) const
No-op, as the union constraint sampler can act on anything.
Definition: union_constraint_sampler.h:196
constraint_samplers::UnionConstraintSampler::getName
const std::string & getName() const override
Get the name of the constraint sampler, for debugging purposes should be in CamelCase format.
Definition: union_constraint_sampler.h:225
moveit::core::RobotState
Representation of a robot's state. This includes position, velocity, acceleration and effort.
Definition: robot_state.h:155
constraint_samplers::UnionConstraintSampler::sample
bool sample(moveit::core::RobotState &state, const moveit::core::RobotState &reference_state, unsigned int max_attempts) override
Produces a sample from all configured samplers.
Definition: union_constraint_sampler.cpp:158
constraint_samplers::UnionConstraintSampler::samplers_
std::vector< ConstraintSamplerPtr > samplers_
Holder for sorted internal list of samplers.
Definition: union_constraint_sampler.h:232
constraint_samplers
The constraint samplers namespace contains a number of methods for generating samples based on a cons...
Definition: constraint_sampler.h:51
constraint_samplers::UnionConstraintSampler::configure
bool configure(const moveit_msgs::Constraints &constraint) override
No-op, as the union constraint sampler is for already configured samplers.
Definition: union_constraint_sampler.h:183
constraint_samplers::UnionConstraintSampler::UnionConstraintSampler
UnionConstraintSampler(const planning_scene::PlanningSceneConstPtr &scene, const std::string &group_name, const std::vector< ConstraintSamplerPtr > &samplers)
Constructor, which will re-order its internal list of samplers on construction.
Definition: union_constraint_sampler.cpp:139
constraint_samplers::UnionConstraintSampler::getSamplers
const std::vector< ConstraintSamplerPtr > & getSamplers() const
Gets the sorted internal list of constraint samplers.
