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Indicate to the memory manager that this resource is no longer active.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 362 of file ClImportTensorHandle.hpp.

363  {
364  return m_Tensor.info()->data_type();
365  }

◆ 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 360 of file ClImportTensorHandle.hpp.

360 { 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 377 of file ClImportTensorHandle.hpp.

378  {
379  return armcomputetensorutils::GetShape(m_Tensor.info()->tensor_shape());
380  }

◆ 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 372 of file ClImportTensorHandle.hpp.

373  {
374  return armcomputetensorutils::GetStrides(m_Tensor.info()->strides_in_bytes());
375  }

◆ Map()

virtual const void* Map ( bool  blocking = true) 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 353 of file ClImportTensorHandle.hpp.

354  {
355  IgnoreUnused(blocking);
356  return static_cast<const void*>(m_Tensor.buffer() + m_Tensor.info()->offset_first_element_in_bytes());
