size_type Dune::DynamicVector< K, Allocator >::capacity ( ) const

inline

Number of elements for which memory has been allocated.

capacity() is always greater than or equal to size().

inlineinherited

vector space subtract scalar from all comps

we use enable_if to avoid an ambiguity, if the function parameter can be converted to value_type implicitly. (see FS#1457)

The function is only enabled, if the parameter is directly convertible to value_type.
