vtkFloatArray is an array of floating point numbers. It provides methods for insertion and retrieval of floating point values, and will automatically resize itself to hold new data.

Examples:

Member Function Documentation

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

Allocate memory for this array. Delete old storage only if necessary.

Implements vtkDataArray.

void vtkFloatArray::DeepCopy vtkDataArray   fa [inline]
 

For legacy compatibility. Do not use.

Reimplemented from vtkDataArray.

void vtkFloatArray::DeepCopy vtkDataArray   fa [virtual]
 

Deep copy of another float array.

Reimplemented from vtkDataArray.

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.

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

Return the data component at the ith tuple and jth component location. Note that i is less than NumberOfTuples and j is less than NumberOfComponents.

Reimplemented from vtkDataArray.

int vtkFloatArray::GetDataType   [inline, virtual]
 

Get the data type.

Implements vtkDataArray.

void vtkFloatArray::GetTuple const int    i,
float *    tuple
[virtual]
 

Copy the tuple value into a user-provided array.

Implements vtkDataArray.

float* vtkFloatArray::GetTuple const int    i [virtual]
 

Get a pointer to a tuple at the ith location.

Implements vtkDataArray.

float vtkFloatArray::GetValue const int    id [inline]
 

Get the data at a particular index.

void* vtkFloatArray::GetVoidPointer const int    id [inline, virtual]
 

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

Implements vtkDataArray.

void vtkFloatArray::Initialize   [virtual]
 

Release storage and reset array to initial state.

Implements vtkDataArray.

void vtkFloatArray::InsertComponent const int    i,
const int    j,
const float    c
[virtual]
 

Insert the data component at ith tuple and jth component location. Note that memory allocation is performed as necessary to hold the data.

Reimplemented from vtkDataArray.

int vtkFloatArray::InsertNextTuple const float *    tuple [virtual]
 

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

Implements vtkDataArray.

int vtkFloatArray::InsertNextValue const float    f [inline]
 

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

void vtkFloatArray::InsertTuple const int    i,
const float *    tuple
[virtual]
 

Insert (memory allocation performed) the tuple into the ith location in the array.

Implements vtkDataArray.

void vtkFloatArray::InsertValue const int    id,
const float    f
[inline]
 

Insert data at a specified position in the array.

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.

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.

vtkDataArray* vtkFloatArray::MakeObject   [virtual]
 

Create the same type object as this (virtual constructor).

Implements vtkDataArray.

vtkFloatArray* vtkFloatArray::New   [static]
 

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

Reimplemented from vtkObject.

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.

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::SetArray float *    array,
int    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.

void vtkFloatArray::SetComponent const int    i,
const int    j,
const float    c
[virtual]
 

Set the data component at the ith tuple and jth component location. Note that i is less than NumberOfTuples and j is less than NumberOfComponents. Make sure enough memory has been allocated (use SetNumberOfTuples() and SetNumberOfComponents()).

Reimplemented from vtkDataArray.

void vtkFloatArray::SetNumberOfTuples const int    number [virtual]
 

Set the number of n-tuples in the array.

Implements vtkDataArray.

void vtkFloatArray::SetNumberOfValues const int    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.

void vtkFloatArray::SetTuple const int    i,
const float *    tuple
[virtual]
 

Set the tuple value at the ith location in the array.

Implements vtkDataArray.

void vtkFloatArray::SetValue const int    id,
const float    value
[inline]
 

Set the data at a particular index. Does not do range checking. Make sure you use the method SetNumberOfValues() before inserting data.

void vtkFloatArray::Squeeze   [inline, virtual]
 

Resize object to just fit data requirement. Reclaims extra memory.

Implements vtkDataArray.

float * vtkFloatArray::WritePointer const int    id,
const int    number
[inline]
 

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.
