Detailed Description

template<typename T>
class SdfListOp< T >

Value type representing a list-edit operation.

SdfListOp is a value type representing an operation that edits a list. It may add or remove items, reorder them, or replace the list entirely.

Constructor & Destructor Documentation

template<typename T>
SDF_API SdfListOp< T >::SdfListOp ( )

Create an empty ListOp in non-explicit mode.

Member Function Documentation

template<typename T>
SDF_API void SdfListOp< T >::ApplyOperations ( ItemVector vec,
const ApplyCallback cb = ApplyCallback() 
) const

Applies edit operations to the given ItemVector. If supplied, cb will be called on each item in the operation vectors before they are applied to vec. Consumers can use this to transform the items stored in the operation vectors to match what's stored in vec.

template<typename T>
SDF_API hboost::optional<SdfListOp<T> > SdfListOp< T >::ApplyOperations ( const SdfListOp< T > &  inner) const

Applies edit operations to the given ListOp.

The result is a ListOp that, when applied to a list, has the same effect as applying inner and then this in sequence.

The result will be empty if the result is not well defined. The result is well-defined when inner and this do not use the 'ordered' or 'added' item lists. In other words, only the explicit, prepended, appended, and deleted portions of SdfListOp are closed under composition with ApplyOperations().

template<typename T>
SDF_API void SdfListOp< T >::Clear ( )

Removes all items and changes the list to be non-explicit.

template<typename T>
SDF_API void SdfListOp< T >::ClearAndMakeExplicit ( )

Removes all items and changes the list to be explicit.

template<typename T>
SDF_API void SdfListOp< T >::ComposeOperations ( const SdfListOp< T > &  stronger,
SdfListOpType  op 
)

Composes a stronger SdfListOp's opinions for a given operation list over this one.

template<typename T>
static SDF_API SdfListOp SdfListOp< T >::Create ( const ItemVector prependedItems = ItemVector(),
const ItemVector appendedItems = ItemVector(),
const ItemVector deletedItems = ItemVector() 
)
static

Create a ListOp in non-explicit mode with the given prependedItems, appendedItems, and deletedItems

template<typename T>
static SDF_API SdfListOp SdfListOp< T >::CreateExplicit ( const ItemVector explicitItems = ItemVector())
static

Create a ListOp in explicit mode with the given explicitItems.

template<typename T>
const ItemVector& SdfListOp< T >::GetAddedItems ( ) const
inline

Returns the explicit items.

Definition at line 133 of file listOp.h.

template<typename T>
const ItemVector& SdfListOp< T >::GetAppendedItems ( ) const
inline

Returns the explicit items.

Definition at line 145 of file listOp.h.

template<typename T>
const ItemVector& SdfListOp< T >::GetDeletedItems ( ) const
inline

Returns the deleted items.

Definition at line 151 of file listOp.h.

template<typename T>
const ItemVector& SdfListOp< T >::GetExplicitItems ( ) const
inline

Returns the explicit items.

Definition at line 127 of file listOp.h.

template<typename T>
SDF_API const ItemVector& SdfListOp< T >::GetItems ( SdfListOpType  type) const

Return the item vector identified by type.

template<typename T>
const ItemVector& SdfListOp< T >::GetOrderedItems ( ) const
inline

Returns the ordered items.

Definition at line 157 of file listOp.h.

template<typename T>
const ItemVector& SdfListOp< T >::GetPrependedItems ( ) const
inline

Returns the explicit items.

Definition at line 139 of file listOp.h.

template<typename T>
SDF_API bool SdfListOp< T >::HasItem ( const T item) const

Returns true if the given item is in any of the item lists.

template<typename T>
bool SdfListOp< T >::HasKeys ( ) const
inline

Returns true if the editor has an explicit list (even if it's empty) or it has any added, prepended, appended, deleted, or ordered keys.

Definition at line 103 of file listOp.h.

template<typename T>
bool SdfListOp< T >::IsExplicit ( ) const
inline

Returns true if the list is explicit.

Definition at line 121 of file listOp.h.

template<typename T>
SDF_API bool SdfListOp< T >::ModifyOperations ( const ModifyCallback callback)

Modifies operations specified in this object. callback is called for every item in all operation vectors. If the returned key is empty then the key is removed, otherwise it's replaced with the returned key.

Returns true if a change was made, false otherwise.

template<typename T>
bool SdfListOp< T >::operator!= ( const SdfListOp< T > &  rhs) const
inline

Definition at line 256 of file listOp.h.

template<typename T>
bool SdfListOp< T >::operator== ( const SdfListOp< T > &  rhs) const

size_t  n,
const ItemVector newItems 
)

Replaces the items in the specified operation vector in the range (index, index + n] with the given newItems. If newItems is empty the items in the range will simply be removed.
