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Indicate to the memory manager that this resource is no longer active.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 300 of file NeonTensorHandle.hpp.

300 {}

◆ 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
tensorInfothe overidden TensorInfo.

Reimplemented from ITensorHandle.

Definition at line 328 of file NeonTensorHandle.hpp.

329  {
330  return nullptr;
331  };

◆ GetDataType()

virtual arm_compute::DataType GetDataType ( ) const
inlineoverridevirtual

Implements IAclTensorHandle.

Definition at line 305 of file NeonTensorHandle.hpp.

306  {
307  return m_Tensor.info()->data_type();
308  }

◆ 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 303 of file NeonTensorHandle.hpp.

303 { 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 323 of file NeonTensorHandle.hpp.

324  {
325  return armcomputetensorutils::GetShape(m_Tensor.info()->tensor_shape());
326  }

◆ 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 318 of file NeonTensorHandle.hpp.

319  {
320  return armcomputetensorutils::GetStrides(m_Tensor.info()->strides_in_bytes());

Definition at line 301 of file NeonTensorHandle.hpp.

301 {}

◆ Map()

virtual const void* Map ( bool  blocking) const
inlineoverridevirtual

Map the tensor data for access.

Parameters
blockinghint 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 312 of file NeonTensorHandle.hpp.

313  {
314  return static_cast<const void*>(m_Tensor.buffer() + m_Tensor.info()->offset_first_element_in_bytes());
315  }

◆ SetMemoryGroup()
