Member Data Documentation

Object Pothos::Label::data

The data can be anything that can be held by Object.

std::string Pothos::Label::id

The identifier describes the label's type, meaning, or purpose. Identifiers only have meaning in the context of the blocks that are producing and consuming them. So any given pair of blocks need to agree on a particular set of identifiers and their meanings.

unsigned long long Pothos::Label::index

The index specifies an offset into a buffer of elements. To associate with the first element of a buffer, index should be 0. To associate with the Nth element of a buffer, index should be N-1.
