Detailed Description

abstract superclass for arrays.

Date:
2001/11/13 14:09:24
Revision:
1.41

vtkDataArray is an abstract superclass for data array objects. This class defines an API that all array objects must support. Note that the concrete subclasses of this class represent data in native form (char, int, etc.) and often have specialized more efficient methods for operating on this data (for example, getting pointers to data or getting/inserting data in native form).

The logical structure of this class is an array of tuples, where each tuple is made up of n-components (also called a component group), and n is the number of component values in a tuple(n >= 1). Another view of this class is a mxn matrix, where m is the number of tuples, and n is the number of components in a tuple. Thus vtkDataArray can be used to represent scalars (1-4 components), 3D vectors (3 components), texture coordinates (1-3 components), tensors, (9 components) and so on.

Each data array is required to have a character-string name. The naming of the array occurs automatically when it is instantiated, but you are free to name arrays using the SetName() method. (The array name is used for data manipulation.)

)  [inline, virtual]
 

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.

void vtkDataArray::GetDataTypeRange (  double    range[2] ) 
 

These methods return the Min and Max possible range of the native data type. For example if a vtkScalars consists of unsigned char data these will return (0,255).

double vtkDataArray::GetDataTypeMin (    ) 
 

These methods return the Min and Max possible range of the native data type. For example if a vtkScalars consists of unsigned char data these will return (0,255).

double vtkDataArray::GetDataTypeMax (    ) 
 

These methods return the Min and Max possible range of the native data type. For example if a vtkScalars consists of unsigned char data these will return (0,255).

virtual float vtkDataArray::GetMaxNorm (    )  [virtual]
 

Return the maximum norm for the tuples. Note that the max. is computed everytime GetMaxNorm is called.

vtkDataArray* vtkDataArray::CreateDataArray (  int    dataType )  [static]
 

Creates an array for dataType where dataType is one of VTK_BIT, VTK_CHAR, VTK_UNSIGNED_CHAR, VTK_SHORT, VTK_UNSIGNED_SHORT, VTK_INT, VTK_UNSIGNED_INT, VTK_LONG, VTK_UNSIGNED_LONG, VTK_FLOAT, VTK_DOUBLE, VTK_ID_TYPE. Note that the data array returned has be deleted by the user.
