DGtal::concepts::CIncrementalPrimitiveComputer< T > Struct Template Reference
DGtal Concepts

Aim: Defines the concept describing an object that computes some primitive from input points given one at a time, while keeping some internal state. At any moment, the object is supposed to store at least one valid primitive for the formerly given input points. A primitive is an informal word that describes some family of objects that share common characteristics. Often, the primitives are geometric, e.g. digital planes. More...

Detailed Description

template<typename T>
struct DGtal::concepts::CIncrementalPrimitiveComputer< T >

Aim: Defines the concept describing an object that computes some primitive from input points given one at a time, while keeping some internal state. At any moment, the object is supposed to store at least one valid primitive for the formerly given input points. A primitive is an informal word that describes some family of objects that share common characteristics. Often, the primitives are geometric, e.g. digital planes.

Description of concept 'CIncrementalPrimitiveComputer'

Refinement of CPrimitiveComputer

Associated types

  • Primitive, the type that defines the primitive.
  • Point: the type of the input points.

Notation

Valid expressions and semantics

Name Expression Type requirements Return type Precondition Semantics Post condition Complexity
insert new point x.extend(p) bool tries to find a primitive that matches the new point p and all formerly given input points, return true on success (state may change), false otherwise (state is unchanged)
check new point x.isExtendable(p) bool tries to find a primitive that matches the new point p and all formerly given input points, return true only if it possible, the state is always unchanged
