Detailed Description

template<typename ValueType, typename DecompositionValueType>
class OpenMS::ims::MassDecomposer< ValueType, DecompositionValueType >

An interface to handle decomposing of integer values/masses over a set of integer weights (alphabet).

An interface that addresses the following "mass decomposition" problems:

• Existence Problem (whether the decomposition of the given mass exists),
• One Decomposition Problem (returns one possible decomposition),
• All Decompositions Problem (returns all possible decompositions),
• Number of Decompositions Problem (returns the number of possible decompositions).

Those problems are solved in integer arithmetic, i.e. only exact solutions are found with no error allowed.

Parameters

ValueType	Type of values to be decomposed.
DecompositionValueType	Type of decomposition elements.

Member Function Documentation

exist()

virtual bool exist ( value_type  mass )

pure virtual

Returns true if the decomposition for the given mass exists, otherwise - false.

Parameters

mass	Mass to be checked on decomposing.

Returns

true, if the decomposition for mass exist, otherwise - false.

getAllDecompositions()

virtual decompositions_type getAllDecompositions ( value_type  mass )

pure virtual

Returns all possible decompositions for the given mass.

Parameters

mass	Mass to be decomposed.

Returns

All possible decompositions of the mass, if there are any exist, otherwise - an empty container.

getDecomposition()

virtual decomposition_type getDecomposition ( value_type  mass )

pure virtual

Returns one possible decomposition of the given mass.

Parameters

mass	Mass to be decomposed.

Returns

The decomposition of the mass, if one exists, otherwise - an empty container.

getNumberOfDecompositions()

virtual decomposition_value_type getNumberOfDecompositions ( value_type  mass )

pure virtual

Returns the number of possible decompositions for the given mass.

Parameters

mass	Mass to be decomposed.

Returns

The number of possible decompositions for the mass.
