Struct ActionSegment<T>

ActionSegment{T} is a data structure that allows access to a segment of an underlying array in order to avoid the copying and allocation of sub-arrays. The segment is defined by the offset into the original array, and an length.

Inherited Members
Namespace: Unity.MLAgents.Actuators
Syntax
public struct ActionSegment<T> : IEnumerable<T>, IEnumerable, IEquatable<ActionSegment<T>> where T : struct
Type Parameters
Name Description
T

The type of object stored in the underlying Array

Constructors

ActionSegment(T[])

Construct an ActionSegment<T> with just an actionArray. The Offset will be set to 0 and the Length will be set to actionArray.Length.

Declaration
public ActionSegment(T[] actionArray)
Parameters
Type Name Description
T[] actionArray

The action array to use for the this segment.

ActionSegment(T[], Int32, Int32)

Construct an ActionSegment<T> with an underlying array and offset, and a length.

Declaration
public ActionSegment(T[] actionArray, int offset, int length)
Parameters
Type Name Description
T[] actionArray

The underlying array which this segment has a view into
Int32 offset

The zero-based offset into the underlying array.
Int32 length

The length of the segment.

Fields

Empty

An Empty segment which has an offset of 0, a Length of 0, and it's underlying array is also empty.

Declaration
public static ActionSegment<T> Empty
Field Value
Type Description
ActionSegment<T>

Length

The number of items this segment can access in the underlying array.

Declaration
public readonly int Length
Field Value
Type Description
Int32

Offset

The zero-based offset into the original array at which this segment starts.

Declaration
public readonly int Offset
Field Value
Type Description
Int32

Properties

Array

Declaration
public T[] Array { get; }
Property Value
Type Description

Item[Int32]

Allows access to the underlying array using array syntax.

Declaration
public T this[int index] { get; set; }
Parameters
Type Name Description
Int32 index

The zero-based index of the segment.
Property Value
Type Description
T
Exceptions
Type Condition
IndexOutOfRangeException

Thrown when the index is less than 0 or greater than or equal to Length
