Constructor & Destructor Documentation

ValueBuffer ( PagedArray &  parent )

inline

Constructor from a PageArray.

ValueBuffer ( const ValueBuffer &  other )

inline

Warning

This copy-constructor is shallow in the sense that no elements are copied, i.e. size = 0.

~ValueBuffer ( )

inline

Destructor that transfers an buffered values to the parent PagedArray.

Member Function Documentation

void flush ( )

inline

Manually transfers the values in this buffer to the parent PagedArray.

Note

This method is also called by the destructor and push_back so it should only be called if one manually wants to sync up the buffer with the array, e.g. during debugging.

ValueBuffer& operator= ( const ValueBuffer &  )

delete

static size_t pageSize ( )

inlinestatic

PagedArrayType& parent ( ) const

inline

Return a reference to the parent PagedArray.

void push_back ( const ValueT &  v )

inline

Add a value to the buffer and increment the size.

If the internal memory page is full it will automaically flush the page to the parent PagedArray.

size_t size ( ) const

inline

Return the current number of elements cached in this buffer.
