Member Function Documentation

add() [1/2]

void TripleViewBatch::add

(

const TriplePtr &

triple

)

Adds a triple to the batch, and attempts to take over ownership of the triple. If this fails, a new copy of the triple is created and added to the batch.

Parameters

triple

a triple.

Definition at line 42 of file TripleContainer.cpp.

                                                 {
    if (actualSize_ < batchSize_) {
        auto &entry = data_[actualSize_++];

add() [2/2]

void knowrob::TripleViewBatch::add

(
