Detailed Description

abstract superclass for arrays of numeric data

vtkDataArray is an abstract superclass for data array objects containing numeric data. It extends the API defined in vtkAbstractArray. 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). Subclasses of vtkDataArray are assumed to contain data whose components are meaningful when cast to and from double.

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

void vtkDataArray::PrintSelf	(	ostream &	os,

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkAbstractArray.

Reimplemented in vtkMappedDataArray< Scalar >, vtkTestDataArray< ArrayT >, vtkIntArray, vtkUnsignedLongArray, vtkLongArray, vtkFloatArray, vtkLongLongArray, vtkShortArray, vtkUnsignedIntArray, vtkUnsignedLongLongArray, vtkUnsignedShortArray, vtkDoubleArray, vtkIdTypeArray, vtkUnsignedCharArray, vtkSignedCharArray, vtkCPExodusIIResultsArrayTemplate< Scalar >, vtkPeriodicDataArray< Scalar >, and vtkCPExodusIINodalCoordinatesTemplate< Scalar >.

vtkDataArray * vtkDataArray::FastDownCast ( vtkAbstractArray * source )

inlinestatic

Perform a fast, safe cast from a vtkAbstractArray to a vtkDataArray.

This method checks if source->GetArrayType() returns DataArray or a more derived type, and performs a static_cast to return source as a vtkDataArray pointer. Otherwise, NULL is returned.

Definition at line 492 of file vtkDataArray.h.

int vtkDataArray::IsNumeric ( )

inlineoverridevirtual

This method is here to make backward compatibility easier.

It must return true if and only if an array contains numeric data. All vtkDataArray subclasses contain numeric data, hence this method always returns 1(true).

Implements vtkAbstractArray.

Definition at line 74 of file vtkDataArray.h.

int vtkDataArray::GetElementComponentSize ( )

inlineoverridevirtual

Return the size, in bytes, of the lowest-level element of an array.
