Detailed Description

a vtkAbstractArray subclass for strings

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

◆ GetVoidPointer()

void * vtkStringArray::GetVoidPointer ( vtkIdType valueIdx )

inlineoverridevirtual

Return a void pointer.

For image pipeline interface and other special pointer manipulation. Use of this method is discouraged, as newer arrays require a deep-copy of the array data in order to return a suitable pointer. See vtkArrayDispatch for a safer alternative for fast data access.

Implements vtkAbstractArray.

Definition at line 358 of file vtkStringArray.h.

◆ DeepCopy()

void vtkStringArray::DeepCopy ( vtkAbstractArray * aa )

overridevirtual

◆ SetArray()

void vtkStringArray::SetArray	(	vtkStdString *	array,
		vtkIdType	size,
		int	save,
		int	deleteMethod = `VTK_DATA_ARRAY_DELETE`
	)

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 supplied array. If save is 0, then this class is free to delete the array when it cleans up or reallocates using the provided free function If the delete method is VTK_DATA_ARRAY_USER_DEFINED a custom free function can be assigned to be called using SetArrayFreeFunction, if no custom function is assigned we will default to delete[].

◆ SetVoidArray() [1/2]

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

inlineoverride

Definition at line 380 of file vtkStringArray.h.

◆ SetVoidArray() [2/2]

inlineoverride

Definition at line 384 of file vtkStringArray.h.

◆ SetArrayFreeFunction()

void vtkStringArray::SetArrayFreeFunction ( void(*)(void *) callback )

overridevirtual

This method allows the user to specify a custom free function to be called when the array is deallocated.

Calling this method will implicitly mean that the given free function will be called when the class cleans up or reallocates memory.

Implements vtkAbstractArray.

◆ GetActualMemorySize()

unsigned long vtkStringArray::GetActualMemorySize ( ) const

overridevirtual

Return the memory in kibibytes (1024 bytes) 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.

◆ NewIterator()

vtkArrayIterator * vtkStringArray::NewIterator ( )

overridevirtual

Returns a vtkArrayIteratorTemplate<vtkStdString>.

Implements vtkAbstractArray.

◆ GetDataSize()

vtkIdType vtkStringArray::GetDataSize ( ) const

overridevirtual

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.

vtkIdType vtkStringArray::LookupValue ( vtkVariant value )

overridevirtual

Return the indices where a specific value appears.

		vtkIdList *	ids
	)

◆ DataChanged()

void vtkStringArray::DataChanged ( )

overridevirtual

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.

◆ DataElementChanged()

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.

◆ ClearLookup()

void vtkStringArray::ClearLookup ( )

overridevirtual

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.
