* @class vtkCharArray
|
||
|
|
* @brief dynamic, self-adjusting array of char
|
||
|
|
*
|
||
|
|
* vtkCharArray is an array of values of type char. It provides
|
||
|
|
* methods for insertion and retrieval of values and will
|
||
|
|
* automatically resize itself to hold new data.
|
||
|
|
*
|
||
|
|
* @warning
|
||
|
|
* This class should be avoided in favor of either
|
||
|
|
* vtkSignedCharArray or vtkUnsignedCharArray. On some systems
|
||
|
|
* the underlying data will be stored as unsigned chars and others
|
||
|
|
* it will be stored as signed chars. Additionally, saving this
|
||
|
|
* array out and then reading it back in it could be transformed to
|
||
|
|
* a vtkSignedCharArray or vtkUnsignedCharArray and if that happens
|
||
|
|
* the result of a vtkCharArray::SafeDownCast() of that pointer will be
|
||
|
|
* a null pointer.
