int vtkGenericAttributeCollection::GetNumberOfAttributes ( )

Return the number of attributes (e.g., instances of vtkGenericAttribute) in the collection.

Postcondition:: positive_result: result>=0

int vtkGenericAttributeCollection::GetNumberOfComponents ( )

Return the number of components. This is the sum of all components found in all attributes.

Postcondition:: positive_result: result>=0

int vtkGenericAttributeCollection::GetNumberOfPointCenteredComponents ( )

Return the number of components. This is the sum of all components found in all point centered attributes.

Postcondition:: positive_result: result>=0

int vtkGenericAttributeCollection::GetMaxNumberOfComponents ( )

Maximum number of components encountered among all attributes.

Postcondition:: positive_result: result>=0; valid_result: result<=GetNumberOfComponents()

unsigned long vtkGenericAttributeCollection::GetActualMemorySize ( )

Actual size of the data in kilobytes; only valid after the pipeline has updated. It is guaranteed to be greater than or equal to the memory required to represent the data.

int vtkGenericAttributeCollection::IsEmpty ( )

Indicate whether the collection contains any attributes.

Postcondition:: definition: result==(GetNumberOfAttributes()==0)

vtkGenericAttribute* vtkGenericAttributeCollection::GetAttribute ( int i )

Return a pointer to the ith instance of vtkGenericAttribute.

Precondition:: not_empty: !IsEmpty(); valid_i: i>=0 && i<GetNumberOfAttributes()

Postcondition:: result_exists: result!=0

int vtkGenericAttributeCollection::FindAttribute ( const char * name )

Return the index of the attribute named `name'. Return the non-negative index if found. Return -1 otherwise.

Precondition:: name_exists: name!=0

Postcondition:: valid_result: (result==-1) || (result>=0) && (result<=GetNumberOfAttributes())

int vtkGenericAttributeCollection::GetAttributeIndex ( int i )

Return the index of the first component of attribute `i' in an array of format attrib0comp0 attrib0comp1 ... attrib4comp0 ...

Precondition:: valid_i: i>=0 && i<GetNumberOfAttributes(); is_point_centered: GetAttribute(i)->GetCentering()==vtkPointCentered

void vtkGenericAttributeCollection::InsertNextAttribute ( vtkGenericAttribute * a )

Add the attribute `a' to the end of the collection.

Precondition:: a_exists: a!=0

Postcondition:: more_items: GetNumberOfAttributes()==old GetNumberOfAttributes()+1; a_is_set: GetAttribute(GetNumberOfAttributes()-1)==a

void vtkGenericAttributeCollection::InsertAttribute	(	int	i,
		vtkGenericAttribute *	a
	)

Replace the attribute at index `i' by `a'.

Precondition:: not_empty: !IsEmpty(); a_exists: a!=0; valid_i: i>=0 && i<GetNumberOfAttributes()

Postcondition:: same_size: GetNumberOfAttributes()==old GetNumberOfAttributes(); item_is_set: GetAttribute(i)==a

void vtkGenericAttributeCollection::RemoveAttribute ( int i )

Remove the attribute at `i'.

Precondition:: not_empty: !IsEmpty(); valid_i: i>=0 && i<GetNumberOfAttributes()

Postcondition:: fewer_items: GetNumberOfAttributes()==old GetNumberOfAttributes()-1

void vtkGenericAttributeCollection::Reset ( )

Remove all attributes.

Postcondition:: is_empty: GetNumberOfAttributes()==0

void vtkGenericAttributeCollection::DeepCopy ( vtkGenericAttributeCollection * other )

Copy, without reference counting, the other attribute array.

Precondition:: other_exists: other!=0; not_self: other!=this

Postcondition:: same_size: GetNumberOfAttributes()==other->GetNumberOfAttributes()

void vtkGenericAttributeCollection::ShallowCopy ( vtkGenericAttributeCollection * other )

Copy, via reference counting, the other attribute array.

Precondition:: other_exists: other!=0; not_self: other!=this

Postcondition:: same_size: GetNumberOfAttributes()==other->GetNumberOfAttributes()

virtual unsigned long int vtkGenericAttributeCollection::GetMTime ( ) [virtual]

vtkAttributeCollection is a composite object and needs to check each member of its collection for modified time.

Reimplemented from vtkObject.

virtual int vtkGenericAttributeCollection::GetActiveAttribute ( ) [virtual]

Index of the attribute to be processed (not necessarily scalar).

Precondition:: not_empty: !IsEmpty()

Postcondition:: valid_result: result>=0 && result<GetNumberOfAttributes()

virtual int vtkGenericAttributeCollection::GetActiveComponent ( ) [virtual]

Component of the active attribute to be processed. -1 means module.

Precondition:: not_empty: GetNumberOfAttributes()>0

Postcondition:: valid_result: result>=-1 && result<GetAttribute(GetActiveAttribute())->GetNumberOfComponents()

void vtkGenericAttributeCollection::SetActiveAttribute	(	int	attribute,
		int	component = `0`
	)

Set the scalar attribute to be processed. -1 means module.

Precondition:: not_empty: !IsEmpty(); valid_attribute: attribute>=0 && attribute<GetNumberOfAttributes(); valid_component: component>=-1 && component<GetAttribute(attribute)->GetNumberOfComponents()

Number of attributes to interpolate.

Precondition:: not_empty: !IsEmpty()

Postcondition:: positive_result: result>=0

int* vtkGenericAttributeCollection::GetAttributesToInterpolate ( )

Indices of attributes to interpolate.

Precondition:: not_empty: !IsEmpty()

Postcondition:: valid_result: GetNumberOfAttributesToInterpolate()>0 implies result!=0

int vtkGenericAttributeCollection::HasAttribute	(	int	size,
		int *	attributes,
		int	attribute
	)

Does the array `attributes' of size `size' have `attribute'?

Precondition:: positive_size: size>=0; valid_attributes: size>0 implies attributes!=0

void vtkGenericAttributeCollection::SetAttributesToInterpolate	(	int	size,
		int *	attributes
	)

Set the attributes to interpolate.

Precondition:: not_empty: !IsEmpty(); positive_size: size>=0; valid_attributes: size>0 implies attributes!=0; valid_attributes_contents: attributes!=0 implies !HasAttributes(size,attributes,GetActiveAttribute())

Postcondition:: is_set: (GetNumberOfAttributesToInterpolate()==size)&& (GetAttributesToInterpolate()==attributes)

void vtkGenericAttributeCollection::SetAttributesToInterpolateToAll ( )

Set the attributes to interpolate.

Precondition:: not_empty: !IsEmpty(); positive_size: size>=0; valid_attributes: size>0 implies attributes!=0; valid_attributes_contents: attributes!=0 implies !HasAttributes(size,attributes,GetActiveAttribute())
