Detailed Description

template<typename VectorType = ::Vector<double>>
class PrimitiveVectorMemory< VectorType >

Simple memory management. See the documentation of the base class for a description of its purpose.

This class allocates and deletes vectors as needed from the global heap, i.e. performs no specially adapted actions for memory management.

Member Function Documentation

template<typename VectorType = ::Vector<double>>
virtual VectorType* PrimitiveVectorMemory< VectorType >::alloc ( )

Return a pointer to a new vector. The number of elements or their subdivision into blocks (if applicable) is unspecified and users of this function should reset vectors to their proper size. The same holds for the contents of vectors: they are unspecified.

For the present class, calling this function will allocate a new vector on the heap and returning a pointer to it.

Implements VectorMemory< VectorType >.

Definition at line 183 of file vector_memory.h.

template<typename VectorType = ::Vector<double>>
virtual void PrimitiveVectorMemory< VectorType >::free ( const VectorType *const  v)

Return a vector and indicate that it is not going to be used any further by the instance that called alloc() to get a pointer to it.

For the present class, this means that the vector is returned to the global heap.

Implements VectorMemory< VectorType >.
