Member Function Documentation

Allocate()

virtual void Allocate ( )

inlineoverridevirtual

Indicate to the memory manager that this resource is no longer active.

This is used to compute overlapping lifetimes of resources.

Implements ITensorHandle.

DecorateTensorHandle()

virtual std::shared_ptr<ITensorHandle> DecorateTensorHandle ( const TensorInfo &  tensorInfo )

inlineoverridevirtual

Returns a decorated version of this TensorHandle allowing us to override the TensorInfo for it.

Parameters

tensorInfo

the overidden TensorInfo.

Reimplemented from ITensorHandle.

Definition at line 477 of file NeonTensorHandle.hpp.

    {
        return nullptr;
    };

GetDataType()

virtual arm_compute::DataType GetDataType ( ) const

inlineoverridevirtual

Implements IAclTensorHandle.

        return m_Tensor.info()->data_type();
    }

References NeonTensorDecorator::info().

GetParent()

virtual ITensorHandle* GetParent ( ) const

inlineoverridevirtual

Get the parent tensor if this is a subtensor.

Returns

a pointer to the parent tensor. Otherwise nullptr if not a subtensor.

Implements ITensorHandle.

Definition at line 452 of file NeonTensorHandle.hpp.

{ return nullptr; }

GetShape()

TensorShape GetShape ( ) const

inlineoverridevirtual

Get the number of elements for each dimension ordered from slowest iterating dimension to fastest iterating dimension.

Returns

a TensorShape filled with the number of elements for each dimension.

Implements ITensorHandle.

Definition at line 472 of file NeonTensorHandle.hpp.

    {
        return armcomputetensorutils::GetShape(m_Tensor.info()->tensor_shape());
    }

GetStrides()

TensorShape GetStrides ( ) const

inlineoverridevirtual

Get the strides for each dimension ordered from largest to smallest where the smallest value is the same as the size of a single element in the tensor.

Returns

a TensorShape filled with the strides for each dimension

Implements ITensorHandle.

Definition at line 467 of file NeonTensorHandle.hpp.

    {
        return armcomputetensorutils::GetStrides(m_Tensor.info()->strides_in_bytes());

Map()

virtual const void* Map ( bool  blocking ) const

inlineoverridevirtual

Map the tensor data for access.

Parameters

blocking

hint to block the calling thread until all other accesses are complete. (backend dependent)

Returns

pointer to the first element of the mapped data.

Implements ITensorHandle.

Definition at line 461 of file NeonTensorHandle.hpp.

    {
        return static_cast<const void*>(m_Tensor.buffer() + m_Tensor.info()->offset_first_element_in_bytes());
