The BTK MutableAtomicStructure Concept

Description:

An object that models a mutable atomic structure (i.e. a structure that supports the insertion or deletion of atoms or changes in type).

Concept Refines:

STL Concepts:

• Sequence

BTK Concepts:

• AtomicStructure
• ChemicallyTyped

Notation:

X -- A type that models the MutableAtomicStructure Concept
x -- An object of type X

Associated Types:

None beyond those of the refined concepts.

Definitions:

None.

Valid Expressions:

In addition to those expressions specified by the refined concepts, the following expressions must be valid:

Expression	Type Requirements	Precondition	Semantics	Postcondition	Complexity
X::reference x.operator[](X::size_type n)		n is in the range [0,x.size())	Gets a non-const reference to the n'th atom in the structure.

Models:

• BTK::MOLECULES::AtomicStructure
• BTK::MOLECULES::Molecule
