Detailed Description

Subclass of vtkAbstractArray that holds vtkStdStrings.

Date
2009-03-12 16:21:41
Revision
1.10

Points and cells may sometimes have associated data that are stored as strings, e.g. many information visualization projects. This class provides a reasonably clean way to store and access those.

Warning:
Wrapping support for the Set/Get/Insert methods is a little strange. The Tcl/Python/Java wrappers treat vtkStdString as const char * right now instead of dealing with native strings. This is why there are two versions of every Set method: one (which you should use in C++ code) taking a vtkStdString argument and one (used by the wrapper) taking a const char * argument.

If you'd like to look into modifying the wrappers to handle this properly, go right ahead...

void vtkStringArray::Initialize (  )  [virtual]

Release storage and reset array to initial state.

Implements vtkAbstractArray.

int vtkStringArray::GetDataTypeSize (  )  [virtual]

Implements vtkAbstractArray.

virtual void vtkStringArray::SetTuple ( vtkIdType  i,
vtkIdType  j,
vtkAbstractArray source 
) [virtual]

Set the tuple at the ith location using the jth tuple in the source array. This method assumes that the two arrays have the same type and structure. Note that range checking and memory allocation is not performed; use in conjunction with SetNumberOfTuples() to allocate space.

Implements vtkAbstractArray.

virtual void vtkStringArray::InsertTuple ( vtkIdType  i,
vtkIdType  j,
vtkAbstractArray source 
) [virtual]

virtual void vtkStringArray::InterpolateTuple ( vtkIdType  i,
vtkIdType  id1,
vtkAbstractArray source1,
vtkIdType  id2,
vtkAbstractArray source2,
double  t 
) [virtual]

Insert the ith tuple in this array as interpolated from the two values, p1 and p2, and an interpolation factor, t. The interpolation factor ranges from (0,1), with t=0 located at p1. This method assumes that the three arrays are of the same type. p1 is value at index id1 in source1, while, p2 is value at index id2 in source2.

Implements vtkAbstractArray.

virtual void vtkStringArray::GetTuples ( vtkIdList ptIds,
vtkAbstractArray output

Implements vtkAbstractArray.

Definition at line 201 of file vtkStringArray.h.

void vtkStringArray::DeepCopy ( vtkAbstractArray aa  )  [virtual]

Deep copy of another string array. Will complain and change nothing if the array passed in is not a vtkStringArray.

Reimplemented from vtkAbstractArray.

void vtkStringArray::SetArray ( vtkStdString 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. If save is 0, then this class is free to delete the array when it cleans up or reallocates. In that case, it is required that the array was allocated using the C++ new operator (and not malloc).

virtual void vtkStringArray::SetVoidArray ( void *  array,
vtkIdType  size,
int  save 
) [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. 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.

Definition at line 222 of file vtkStringArray.h.

unsigned long vtkStringArray::GetActualMemorySize (  )  [virtual]

Return the memory in kilobytes consumed by this data array. Used to support streaming and reading/writing data. The value returned is guaranteed to be greater than or equal to the memory required to actually represent the data represented by this object. The information returned is valid only after the pipeline has been updated. This function takes into account the size of the contents of the strings as well as the string containers themselves.

Implements vtkAbstractArray.

virtual vtkArrayIterator* vtkStringArray::NewIterator (  )  [virtual]

Returns a vtkArrayIteratorTemplate<vtkStdString>.

Implements vtkAbstractArray.

virtual vtkIdType vtkStringArray::GetDataSize (  )  [virtual]

Returns the size of the data in DataTypeSize units. Thus, the number of bytes for the data can be computed by GetDataSize() * GetDataTypeSize(). The size computation includes the string termination character for each string.

Reimplemented from vtkAbstractArray.

virtual vtkIdType vtkStringArray::LookupValue ( vtkVariant  value  )  [virtual]

Return the indices where a specific value appears.

Implements vtkAbstractArray.

virtual void vtkStringArray::LookupValue ( vtkVariant  value,
vtkIdList ids 
) [virtual]

Return the indices where a specific value appears.

Implements vtkAbstractArray.

vtkIdType vtkStringArray::LookupValue ( vtkStdString  value  ) 

Return the indices where a specific value appears.

void vtkStringArray::LookupValue ( vtkStdString  value,
vtkIdList ids 
)

Return the indices where a specific value appears.

vtkIdType vtkStringArray::LookupValue ( const char *  value  ) 

Return the indices where a specific value appears.

void vtkStringArray::LookupValue ( const char *  value,
vtkIdList ids 
)

Return the indices where a specific value appears.

virtual void vtkStringArray::DataChanged (  )  [virtual]

Tell the array explicitly that the data has changed. This is only necessary to call when you modify the array contents without using the array's API (i.e. you retrieve a pointer to the data and modify the array contents). You need to call this so that the fast lookup will know to rebuild itself. Otherwise, the lookup functions will give incorrect results.

Implements vtkAbstractArray.

virtual void vtkStringArray::DataElementChanged ( vtkIdType  id  )  [virtual]

Tell the array explicitly that a single data element has changed. Like DataChanged(), then is only necessary when you modify the array contents without using the array's API.

virtual void vtkStringArray::ClearLookup (  )  [virtual]

Delete the associated fast lookup data structure on this array, if it exists. The lookup will be rebuilt on the next call to a lookup function.

Implements vtkAbstractArray.
