// .NAME vtkCharArray - dynamic, self-adjusting array of char
// .SECTION Description
// 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.

#ifndef __vtkCharArray_h
#define __vtkCharArray_h

// Tell the template header how to give our superclass a DLL interface.
#if !defined(__vtkCharArray_cxx)
# define VTK_DATA_ARRAY_TEMPLATE_TYPE char

// Fake the superclass for the wrappers.

  // Description:
  // Get the data at a particular index.
  char GetValue(vtkIdType id)

  // Description:
  // Set the data at a particular index. Does not do range checking. Make sure
  // you use the method SetNumberOfValues() before inserting data.
  void SetValue(vtkIdType id, char value)
    { this->RealSuperclass::SetValue(id, value); }

  // Description:
  // Specify the number of values for this object to hold. Does an
  // allocation as well as setting the MaxId ivar. Used in conjunction with
  // SetValue() method for fast insertion.
  void SetNumberOfValues(vtkIdType number)
    { this->RealSuperclass::SetNumberOfValues(number); }

  // Description:
  // Insert data at a specified position in the array.

  // Description:
  // Insert data at the end of the array. Return its location in the array.

    { return this->RealSuperclass::InsertNextValue(f); }

  // Description:
  // Get the address of a particular data index. Make sure data is allocated
  // for the number of items requested. Set MaxId according to the number of
  // data values requested.

  // Description:
  // This method lets the user specify data to be held by the array.  The
  // array argument is a pointer to the data.  size is the size of
  // the array supplied by the user.  Set save to 1 to keep the class
  // from deleting the array when it cleans up or reallocates memory.
  // The class uses the actual array provided; it does not copy the data
  // from the suppled array.
