A vector of blocks with memory management.
BlockVector adds memory management with ordinary copy semantics to the block_vector_unmanaged template.
Error checking: no error checking is provided normally. Setting the compile time switch DUNE_ISTL_WITH_CHECKING enables error checking.

Reserve space.
After calling this method the vector can hold up to capacity values. If the specified capacity is smaller than the current capacity and bigger than the current size space will be freed.
If the template parameter copyOldValues is true the values will be copied. If it is false the old values are lost.
capacity | The maximum number of elements the vector needs to hold. |
copyOldValues | If false no object will be copied and the data might be lost. Default value is true. |

|
inline |
Resize the vector.
After calling this method BlockVector::N() will return size If the capacity of the vector is smaller than the specified size then reserve(size) will be called.
If the template parameter copyOldValues is true the values will be copied if the capacity changes. If it is false the old values are lost.
size | The new size of the vector. |
copyOldValues | If false no object will be copied and the data might be lost. |
