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Indicate to the memory manager that this resource is no longer active.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

GetDataType()

virtual arm_compute::DataType GetDataType ( ) const

inlineoverridevirtual

Implements IClTensorHandle.

Definition at line 258 of file ClTensorHandle.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 256 of file ClTensorHandle.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 270 of file ClTensorHandle.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 265 of file ClTensorHandle.hpp.

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