Functions and constants
index
TypeScriptindexAfter(i: number): numberfunc index(after i: Int) -> IntReturns the position immediately after the given index. The successor of an index must be well defined. For an index `i` into a collection `c`, calling `c.index(after: i)` returns the same index every time. - Parameter i: A valid index of the collection. `i` must be less than `endIndex`. - Returns: The index value immediately after `i`.
index
TypeScriptindexBefore(i: number): numberfunc index(before i: Int) -> IntReturns the position immediately before the given index. - Parameter i: A valid index of the collection. `i` must be greater than `startIndex`. - Returns: The index value immediately before `i`.
append
TypeScriptappend(newElement: number): voidmutating func append(_ newElement: Element)endIndex
TypeScriptget endIndex(): numbervar endIndex: Int { get }The collection's "past the end" position---that is, the position one greater than the last valid subscript argument. When you need a range that includes the last element of a collection, use the half-open range operator (`..<`) with `endIndex`. The `..<` operator creates a range that doesn't include the upper bound, so it's always safe to use with `endIndex`. For example: let numbers = [10, 20, 30, 40, 50] if let index = numbers.firstIndex(of: 30) { print(numbers[index ..< numbers.endIndex]) } // Prints "[30, 40, 50]" If the collection is empty, `endIndex` is equal to `startIndex`.
valueType
TypeScriptstatic get valueType(): USDPrim_Attribute_ValueTypestatic var valueType: USDPrim.Attribute.ValueType { get }init
TypeScriptstatic init(): USDArray<number>init()init
TypeScriptstatic init98238(): USDArray<number>init()init
TypeScriptstatic init38428(): USDArray<number>init()subscript
TypeScriptsubscript(index: number): numbersubscript(index: Int) -> Element { get }Accesses the element at the specified position. The following example accesses an element of an array through its subscript to print its value: var streets = ["Adams", "Bryant", "Channing", "Douglas", "Evarts"] print(streets[1]) // Prints "Bryant" You can subscript a collection with any valid index other than the collection's end index. The end index refers to the position one past the last element of a collection, so it doesn't correspond with an element. - Parameter position: The position of the element to access. `position` must be a valid index of the collection that is not equal to the `endIndex` property. - Complexity: O(1)
isExplicit
TypeScriptget isExplicit(): booleanvar isExplicit: Bool { get }Whether the operation is in explicit mode — i.e., its items replace the entire list during composition.
clearAndMakeExplicit
TypeScriptclearAndMakeExplicit(): voidmutating func clearAndMakeExplicit()Removes all authored slots and switches to explicit mode with no items.
clear
TypeScriptclear(): voidmutating func clear()Removes all authored slots, leaving an empty operation.
compose
TypeScriptcompose(stronger: USDLayer_ListOperation<SDKHandle>, operation: USDLayer_ListOperationType): voidmutating func compose(stronger: USDLayer.ListOperation<T>, for operation: USDLayer.ListOperationType)Composes a stronger operation into this one for the given slot. - Parameters: - stronger: The stronger operation to compose into this one. - operation: The slot to update.
hasKeys
TypeScriptget hasKeys(): booleanvar hasKeys: Bool { get }Whether any operation slot has been authored.
