Detailed Description

Constructor & Destructor Documentation

ConstTensor() [1/3]

ConstTensor ( )

inline

Definition at line 204 of file Tensor.hpp.

: BaseTensor<const void*>() {} // This needs to be redefined explicitly??

ConstTensor() [2/3]

ConstTensor ( const Tensor &  other )

inline

Can be implicitly constructed from non-const Tensor.

Definition at line 207 of file Tensor.hpp.

: BaseTensor<const void*>(other.GetInfo(), other.GetMemoryArea()) {}

ConstTensor() [3/3]

ConstTensor ( const TensorInfo &  info, const ContainerType< T, ContainerArgs... > &  container  )

inline

Constructor from a backing container.

Parameters

container

- An stl-like container type which implements data() and size() methods. Presence of data() and size() is a strong indicator of the continuous memory layout of the container, which is a requirement for Tensor data. Tensor instances do not claim ownership of referenced memory regions, that is, no attempt will be made by ArmNN to free these memory regions automatically.

Definition at line 215 of file Tensor.hpp.

References TensorInfo::GetNumBytes().

        : BaseTensor<const void*>(info, container.data())
    {
        if (container.size() * sizeof(T) != info.GetNumBytes())
        {
            throw InvalidArgumentException("Container size is not correct");
        }
    }
