Detailed Description

template<typename T>
class blender::VArrayImpl< T >

Implements the specifics of how the elements of a virtual array are accessed. It contains a bunch of virtual methods that are wrapped by #VArray.

Member Function Documentation

common_info()

template<typename T >

virtual CommonVArrayInfo blender::VArrayImpl< T >::common_info ( ) const

inlinevirtual

Reimplemented in blender::VArrayImpl_For_GVArray< T >, blender::VArrayImpl_For_Single< T >, blender::VArrayImpl_For_Span< T >, and blender::VArrayImpl_For_Span< typename Container::value_type >.

Definition at line 103 of file BLI_virtual_array.hh.

Referenced by blender::VMutableArrayImpl< T >::set_all().

get()

template<typename T >

virtual T blender::VArrayImpl< T >::get ( int64_t index ) const

pure virtual

Get the element at #index. This does not return a reference, because the value may be computed on the fly.

Implemented in blender::bke::VArrayImpl_For_VertexWeights, blender::VArrayImpl_For_GVArray< T >, blender::VArrayImpl_For_Single< T >, blender::VArrayImpl_For_Span< T >, and blender::VArrayImpl_For_Span< typename Container::value_type >.

materialize()

template<typename T >

virtual void blender::VArrayImpl< T >::materialize ( const IndexMask & mask, T * dst ) const

inlinevirtual

Copy values from the virtual array into the provided span. The index of the value in the virtual array is the same as the index in the span.

Reimplemented in blender::bke::VArrayImpl_For_VertexWeights, blender::VArrayImpl_For_GVArray< T >, blender::VArrayImpl_For_Single< T >, blender::VArrayImpl_For_Span< T >, and blender::VArrayImpl_For_Span< typename Container::value_type >.

Definition at line 112 of file BLI_virtual_array.hh.

References blender::VArrayImpl< T >::get().

materialize_compressed()

template<typename T >

virtual void blender::VArrayImpl< T >::materialize_compressed ( const IndexMask & mask, T * dst ) const

inlinevirtual

Copy values from the virtual array into the provided span. Contrary to materialize, the index in virtual array is not the same as the index in the output span. Instead, the span is filled without gaps.

Reimplemented in blender::VArrayImpl_For_GVArray< T >, blender::VArrayImpl_For_Single< T >, blender::VArrayImpl_For_Span< T >, and blender::VArrayImpl_For_Span< typename Container::value_type >.

materialize_compressed_to_uninitialized()

template<typename T >

virtual void blender::VArrayImpl< T >::materialize_compressed_to_uninitialized ( const IndexMask & mask, T * dst ) const

inlinevirtual

Same as materialize_compressed but #r_span is expected to be uninitialized.

Reimplemented in blender::VArrayImpl_For_GVArray< T >, blender::VArrayImpl_For_Single< T >, blender::VArrayImpl_For_Span< T >, and blender::VArrayImpl_For_Span< typename Container::value_type >.

materialize_to_uninitialized()

template<typename T >

virtual void blender::VArrayImpl< T >::materialize_to_uninitialized ( const IndexMask & mask, T * dst ) const

inlinevirtual

Same as materialize but #r_span is expected to be uninitialized.

Reimplemented in blender::bke::VArrayImpl_For_VertexWeights, blender::VArrayImpl_For_GVArray< T >, blender::VArrayImpl_For_Single< T >, blender::VArrayImpl_For_Span< T >, and blender::VArrayImpl_For_Span< typename Container::value_type >.

size()

template<typename T >

int64_t blender::VArrayImpl< T >::size ( ) const

inline

Definition at line 92 of file BLI_virtual_array.hh.

try_assign_GVArray()

template<typename T >

virtual bool blender::VArrayImpl< T >::try_assign_GVArray ( GVArray & ) const

inlinevirtual

If this virtual wraps another #GVArray, this method should assign the wrapped array to the provided reference. This allows losslessly converting between generic and typed virtual arrays in all cases. Return true when the virtual array was assigned and false when nothing was done.

Reimplemented in blender::VArrayImpl_For_GVArray< T >.

Definition at line 150 of file BLI_virtual_array.hh.

Member Data Documentation

size_

template<typename T >

int64_t blender::VArrayImpl< T >::size_

protected

Number of elements in the virtual array. All virtual arrays have a size, but in some cases it may make sense to set it to the max value.
