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Indicate to the memory manager that this resource is no longer active.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

439  {
440  return m_Tensor.info()->data_type();
441  }

References ClTensorDecorator::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 436 of file ClTensorHandle.hpp.

436 { 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 450 of file ClTensorHandle.hpp.

451  {
452  return armcomputetensorutils::GetShape(m_Tensor.info()->tensor_shape());
453  }

◆ 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 445 of file ClTensorHandle.hpp.

446  {
447  return armcomputetensorutils::GetStrides(m_Tensor.info()->strides_in_bytes());
448  }

◆ GetTensor() [1/2]

arm_compute::ICLTensor const& GetTensor ( ) const
inlineoverridevirtual

◆ Manage()

virtual void Manage ( )
inlineoverridevirtual

Indicate to the memory manager that this resource is active.

◆ 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 425 of file ClTensorHandle.hpp.

426  {
427  m_Tensor.map(blocking);
428  return static_cast<const void*>(m_Tensor.buffer() + m_Tensor.info()->offset_first_element_in_bytes());
429  }
