Detailed Description

These signatures must be reimplemented in subclasses as public, non-virtual methods.

Ideally, they should be inlined and as efficient as possible to ensure the best performance possible.

Function Documentation

GetValue()

template<class DerivedT, class ValueTypeT>

ValueType vtkGenericDataArray< DerivedT, ValueTypeT >::GetValue ( vtkIdType valueIdx ) const

inline

Get the value at valueIdx.

valueIdx assumes AOS ordering.

Note

GetTypedComponent is preferred over this method. It is faster for SOA arrays, and shows equivalent performance for AOS arrays when NumberOfComponents is known to the compiler (See vtkAssume.h).

Definition at line 99 of file vtkGenericDataArray.h.

SetValue()

template<class DerivedT, class ValueTypeT>

void vtkGenericDataArray< DerivedT, ValueTypeT >::SetValue ( vtkIdType valueIdx, ValueType value )

inline

Set the value at valueIdx to value.

valueIdx assumes AOS ordering.

Note

SetTypedComponent is preferred over this method. It is faster for SOA arrays, and shows equivalent performance for AOS arrays when NumberOfComponents is known to the compiler (See vtkAssume.h).

Definition at line 111 of file vtkGenericDataArray.h.

GetTypedTuple()

template<class DerivedT, class ValueTypeT>

void vtkGenericDataArray< DerivedT, ValueTypeT >::GetTypedTuple ( vtkIdType tupleIdx, ValueType * tuple ) const

inline

Copy the tuple at tupleIdx into tuple.

Note

GetTypedComponent is preferred over this method. The overhead of copying the tuple is significant compared to the more performant component-wise access methods, which typically optimize to raw memory access.

Definition at line 125 of file vtkGenericDataArray.h.

SetTypedTuple()

template<class DerivedT, class ValueTypeT>

void vtkGenericDataArray< DerivedT, ValueTypeT >::SetTypedTuple ( vtkIdType tupleIdx, const ValueType * tuple )

inline

Set this array's tuple at tupleIdx to the values in tuple.

Note

SetTypedComponent is preferred over this method. The overhead of copying the tuple is significant compared to the more performant component-wise access methods, which typically optimize to raw memory access.

Definition at line 139 of file vtkGenericDataArray.h.

GetTypedComponent()

template<class DerivedT, class ValueTypeT>

ValueType vtkGenericDataArray< DerivedT, ValueTypeT >::GetTypedComponent ( vtkIdType tupleIdx, int compIdx ) const

inline

Get component compIdx of the tuple at tupleIdx.

This is typically the fastest way to access array data.

Definition at line 150 of file vtkGenericDataArray.h.

SetTypedComponent()

template<class DerivedT, class ValueTypeT>

void vtkGenericDataArray< DerivedT, ValueTypeT >::SetTypedComponent ( vtkIdType tupleIdx, int compIdx, ValueType value )

inline

Set component compIdx of the tuple at tupleIdx to value.

This is typically the fastest way to set array data.

Definition at line 162 of file vtkGenericDataArray.h.

AllocateTuples()

template<class DerivedT, class ValueTypeT>

bool vtkGenericDataArray< DerivedT, ValueTypeT >::AllocateTuples ( vtkIdType numTuples )

inlineprotected

Allocate space for numTuples.

Old data is not preserved. If numTuples == 0, all data is freed.

Definition at line 341 of file vtkGenericDataArray.h.

ReallocateTuples()

template<class DerivedT, class ValueTypeT>

bool vtkGenericDataArray< DerivedT, ValueTypeT >::ReallocateTuples ( vtkIdType numTuples )

inlineprotected

Allocate space for numTuples.

Old data is preserved. If numTuples == 0, all data is freed.
