Member Function Documentation

VertexDataBlock * VertexDataBook::alloc ( size_t  size)
inline

Allocates and returns a new VertexDataBuffer of the requested size.

Definition at line 23 of file vertexDataBook.I.

size_t VertexDataBook::count_allocated_size ( ) const

Returns the total size of all bytes allocated within pages owned by this book.

Definition at line 85 of file vertexDataBook.cxx.

size_t VertexDataBook::count_allocated_size ( VertexDataPage::RamClass  ram_class) const

Returns the total size of all bytes allocated within pages owned by this book that have the indicated ram class.

Definition at line 104 of file vertexDataBook.cxx.

size_t VertexDataBook::count_total_page_size ( ) const

Returns the total size of all bytes owned by all pages owned by this book.

Definition at line 46 of file vertexDataBook.cxx.

size_t VertexDataBook::count_total_page_size ( VertexDataPage::RamClass  ram_class) const

Returns the total size of all bytes owned by all pages owned by this book that have the indicated ram class.

Definition at line 65 of file vertexDataBook.cxx.

int VertexDataBook::get_num_pages ( ) const
inline

Returns the number of pages created for the book.

Definition at line 34 of file vertexDataBook.I.

void VertexDataBook::save_to_disk ( )

Writes all pages to disk immediately, just in case they get evicted later.

It makes sense to make this call just before taking down a loading screen, to minimize chugs from saving pages inadvertently later.
