Member Function Documentation

vtkFloatArray* vtkFloatArray::New (    )  [static]
 

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

virtual const char* vtkFloatArray::GetClassName (    )  [virtual]
 

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkDataArray.

int vtkFloatArray::IsTypeOf (  const char *    type )  [static]
 

Return 1 if this class type 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.

Reimplemented from vtkDataArray.

virtual int vtkFloatArray::IsA (  const char *    type )  [virtual]
 

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.

Reimplemented from vtkDataArray.

vtkFloatArray* vtkFloatArray::SafeDownCast (  vtkObject *    o )  [static]
 

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkDataArray.

void vtkFloatArray::PrintSelf (  ostream &    os,
vtkIndent    indent
)  [virtual]
 

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 vtkDataArray.

int vtkFloatArray::Allocate (  const vtkIdType    sz,
const vtkIdType    ext = 1000
)  [virtual]
 

Allocate memory for this array. Delete old storage only if necessary. Note that ext is no longer used.

Reimplemented from vtkDataArray.

vtkIdType vtkFloatArray::InsertNextTuple (  const float *    tuple )  [virtual]
 

Insert (memory allocation performed) the tuple onto the end of the array.

Reimplemented from vtkDataArray.

vtkIdType vtkFloatArray::InsertNextTuple (  const double *    tuple )  [virtual]
 

Insert (memory allocation performed) the tuple onto the end of the array.

Reimplemented from vtkDataArray.

float vtkFloatArray::GetComponent (  const vtkIdType    i,
const int    j
)  [virtual]

Reimplemented from vtkDataArray.

void vtkFloatArray::SetComponent (  const vtkIdType    i,
const int    j,
const float    c

Definition at line 148 of file vtkFloatArray.h.

void vtkFloatArray::SetNumberOfValues (  const vtkIdType    number )  [inline]
 

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.

Definition at line 214 of file vtkFloatArray.h.

void* vtkFloatArray::GetVoidPointer (  const vtkIdType    id )  [inline, virtual]
 

Get the address of a particular data index. Performs no checks to verify that the memory has been allocated etc.

float* vtkFloatArray::GetPointer (  const vtkIdType    id )  [inline]
 

Get the address of a particular data index. Performs no checks to verify that the memory has been allocated etc.

Deep copy of another float array.

Reimplemented from vtkDataArray.

void vtkFloatArray::SetArray (  float *    array,
vtkIdType    size,
int    save
) 
 

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.
