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Indicate to the memory manager that this resource is no longer active.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

Definition at line 294 of file NeonTensorHandle.hpp.

{}

GetDataType()

virtual arm_compute::DataType GetDataType ( ) const

inlineoverridevirtual

Implements IAclTensorHandle.

Definition at line 299 of file NeonTensorHandle.hpp.

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

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 297 of file NeonTensorHandle.hpp.

{ return parentHandle; }

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 317 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 312 of file NeonTensorHandle.hpp.

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

GetTensor() [1/2]

Definition at line 295 of file NeonTensorHandle.hpp.

{}

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 306 of file NeonTensorHandle.hpp.

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