Detailed Description

template<class _TypePolicy>
class SdfListEditorProxy< _TypePolicy >

Represents a set of list editing operations.

An SdfListEditorProxy allows consumers to specify a transformation to be applied to a list via a set of list editing operations. Given a starting ordered list, it can either replace the result with another ordered list or apply a sequence of three operations: deleting keys, then adding keys to the end (if they aren't already in the starting list), then reordering keys.

The type policy defines the value type that a particular proxy can operate on.

Constructor & Destructor Documentation

◆ SdfListEditorProxy() [1/2]

SdfListEditorProxy ( )
inline

Creates a default proxy object.

The object evaluates to false in a boolean context and all operations on this object have no effect.

Definition at line 57 of file listEditorProxy.h.

◆ SdfListEditorProxy() [2/2]

SdfListEditorProxy ( const std::shared_ptr< Sdf_ListEditor< TypePolicy > > &  listEditor)
inlineexplicit

Creates a new proxy object backed by the supplied list editor.

Definition at line 62 of file listEditorProxy.h.

Member Function Documentation

◆ Add()

void Add ( const value_type &  value)
inline

Definition at line 301 of file listEditorProxy.h.

◆ Append()

void Append ( const value_type &  value)
inline

Definition at line 331 of file listEditorProxy.h.

◆ ApplyEditsToList() [1/2]

void ApplyEditsToList ( value_vector_type *  vec) const
inline

Apply the edits to vec.

Definition at line 101 of file listEditorProxy.h.

◆ ApplyEditsToList() [2/2]

void ApplyEditsToList ( value_vector_type *  vec,
CB  callback 
) const
inline

Apply the edits to vec.

If callback is valid then it's called for every key in the editor before applying it to vec. If the returned key is invalid then the key will not be applied. Otherwise the returned key is applied, allowing callbacks to perform key translation.

Definition at line 114 of file listEditorProxy.h.

◆ ClearEdits()

bool ClearEdits ( )
inline

Removes all keys and changes the editor to have list operations.

Not all list editors support changing their mode. If the mode can't be changed to the mode of other then this does nothing and returns false, otherwise it returns true.

Definition at line 139 of file listEditorProxy.h.

◆ ClearEditsAndMakeExplicit()

bool ClearEditsAndMakeExplicit ( )
inline

Removes all keys and changes the editor to be explicit.

Not all list editors support changing their mode. If the mode can't be changed to the mode of other then this does nothing and returns false, otherwise it returns true.

Definition at line 149 of file listEditorProxy.h.

◆ ContainsItemEdit()

bool ContainsItemEdit ( const value_type &  item,
bool  onlyAddOrExplicit = false 
) const
inline

Check if the given item is explicit, added, prepended, appended, deleted, or ordered by this editor.

If onlyAddOrExplicit is true we only check the added or explicit items.

Definition at line 168 of file listEditorProxy.h.

◆ CopyItems()

bool CopyItems ( const This other)
inline

Copies the keys from other.

This differs from assignment because assignment just makes two list editors refer to the same lists.

Not all list editors support changing their mode. If the mode can't be changed to the mode of other then this does nothing and returns false, otherwise it returns true.

Definition at line 128 of file listEditorProxy.h.

◆ Erase()

void Erase ( const value_type &  value)
inline

Definition at line 361 of file listEditorProxy.h.

◆ GetAddedItems()

ListProxy GetAddedItems ( ) const
inline

Returns the items added by this list editor.

Definition at line 250 of file listEditorProxy.h.

◆ GetAddedOrExplicitItems()

value_vector_type GetAddedOrExplicitItems ( ) const
inline

Deprecated. Please use GetAppliedItems.

Definition at line 280 of file listEditorProxy.h.

◆ GetAppendedItems()

ListProxy GetAppendedItems ( ) const
inline

Returns the items appended by this list editor.

Definition at line 262 of file listEditorProxy.h.

◆ GetAppliedItems()

value_vector_type GetAppliedItems ( ) const
inline

Returns the effective list of items represented by the operations in this list op.

This function should be used to determine the final list of items added instead of looking at the individual explicit, prepended, and appended item lists.

This is equivalent to calling ApplyOperations on an empty item vector.

Definition at line 292 of file listEditorProxy.h.

◆ GetDeletedItems()

ListProxy GetDeletedItems ( ) const
inline

Returns the items deleted by this list editor.

Definition at line 268 of file listEditorProxy.h.

◆ GetExplicitItems()

ListProxy GetExplicitItems ( ) const
inline

Returns the explicitly set items.

Definition at line 244 of file listEditorProxy.h.

◆ GetOrderedItems()

ListProxy GetOrderedItems ( ) const
inline

Returns the items reordered by this list editor.

Definition at line 274 of file listEditorProxy.h.

◆ GetPrependedItems()

ListProxy GetPrependedItems ( ) const
inline

Returns the items prepended by this list editor.

Definition at line 256 of file listEditorProxy.h.

◆ HasKeys()

bool 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 95 of file listEditorProxy.h.

◆ IsExpired()

bool IsExpired ( ) const
inline

Returns true if the list editor is expired.

Definition at line 69 of file listEditorProxy.h.

◆ IsExplicit()

bool IsExplicit ( ) const
inline

Returns true if the editor has an explicit list, false if it has list operations.

Definition at line 80 of file listEditorProxy.h.

◆ IsOrderedOnly()

bool IsOrderedOnly ( ) const
inline

Returns true if the editor is not explicit and allows ordering only.

Definition at line 87 of file listEditorProxy.h.

◆ ModifyItemEdits()

void ModifyItemEdits ( CB  callback)
inline

callback is called for every key.

If the returned key is invalid then the key is removed, otherwise it's replaced with the returned key.

Definition at line 158 of file listEditorProxy.h.

◆ operator bool()

operator bool ( ) const
inlineexplicit

Explicit bool conversion operator.

A ListEditorProxy object converts to true iff the list editor is valid, converts to false otherwise.

Definition at line 380 of file listEditorProxy.h.

◆ Prepend()

void Prepend ( const value_type &  value)
inline

Definition at line 316 of file listEditorProxy.h.

◆ Remove()

void Remove ( const value_type &  value)
inline

Definition at line 346 of file listEditorProxy.h.

◆ RemoveItemEdits()

void RemoveItemEdits ( const value_type &  item)
inline

Remove all occurrences of the given item, regardless of whether the item is explicit, added, prepended, appended, deleted, or ordered.

Definition at line 212 of file listEditorProxy.h.

◆ ReplaceItemEdits()

void ReplaceItemEdits ( const value_type &  oldItem,
const value_type &  newItem 
)
inline

Replace all occurrences of the given item, regardless of whether the item is explicit, added, prepended, appended, deleted or ordered.
