Struct PlaneBoundaryCollection

Represents a collection of concave BoundedPlane boundaries obtained from .

Namespace: UnityEngine.XR.MagicLeap

Syntax

public struct PlaneBoundaryCollection : IEquatable<PlaneBoundaryCollection>

Remarks

Each Magic Leap plane can have multiple plane boundaries. This collection represents the set of all boundaries associated with a particular plane. Note that unlike most boundaries associated with BoundedPlanes, these are not necessarily convex.

The plane boundaries are tied to native resources which are managed by the MagicLeapPlaneSubsystem. Typically, a PlaneBoundaryCollection is only valid until the next call to , so you should not hold onto an instance of this struct past a frame boundary.

Properties

count

The number of boundaries in this collection.

Declaration

public int count { get; }

Property Value

Type	Description
Int32

Item[Int32]

Attempts to get the plane boundary at index and, if successful, copies it to boundaryOut. boundaryOut is resized or created using if necessary.

Declaration

public PlaneBoundary this[int index] { get; }

Parameters

Type	Name	Description
Int32	index	The index of the boundary to retrieve.

Property Value

Type	Description
PlaneBoundary	true if the boundary was successfully retrieved and boundaryOut was populated; otherwise, false.

Exceptions

Type	Condition
InvalidOperationException	Thrown if valid is false.
InvalidOperationException	Thrown if allocator is Allocator.Temp or Allocator.None.
ArgumentOutOfRangeException	Thrown if index is less than zero or greater than or equal to count.

valid

Whether this collection is valid or not. Check for validity before using the index operator.

Declaration

public bool valid { get; }

Property Value

Type	Description
Boolean

Methods

Equals(Object)

IEquatable interface. Compares for equality.

Declaration

public override bool Equals(object obj)

Parameters

Type	Name	Description
Object	obj	The object to compare for equality.

Returns

Type	Description
Boolean	true if obj is of type PlaneBoundaryCollection and compares equal with Equals(PlaneBoundaryCollection).

Overrides

ValueType.Equals(Object)

Equals(PlaneBoundaryCollection)

IEquatable interface. Comapres for equality.

Declaration

public bool Equals(PlaneBoundaryCollection other)

Parameters

Type	Name	Description
PlaneBoundaryCollection	other	The PlaneBoundaryCollection to compare against.

Returns

Type	Description
Boolean	true if all fields of this PlaneBoundaryCollection compare equal to other.

GetEnumerator()

Get an enumerator, compatible with a duck-typed foreach. You typically would not call this directly, but is used by the compiler in a foreach statement.

Declaration

public PlaneBoundaryCollection.Enumerator GetEnumerator()

Returns

Type	Description
PlaneBoundaryCollection.Enumerator	An Enumerator compatible with a duck-typed foreach.

GetHashCode()

Computes a hash code suitable for use in a Dictionary or HashSet.

Declaration

public override int GetHashCode()

Returns

Type	Description
Int32	A hash code suitable for use in a Dictionary or HashSet.

Overrides

ValueType.GetHashCode()

Operators

Equality(PlaneBoundaryCollection, PlaneBoundaryCollection)

Comapres for equality. Same as Equals(PlaneBoundaryCollection).

Declaration

public static bool operator ==(PlaneBoundaryCollection lhs, PlaneBoundaryCollection rhs)

Parameters

Type	Name	Description
PlaneBoundaryCollection	lhs	The left-hand side of the comparison.
PlaneBoundaryCollection	rhs	The right-hand side of the comparison.

Returns

Type	Description
Boolean	true if all fields of this PlaneBoundaryCollection compare equal to other.

Inequality(PlaneBoundaryCollection, PlaneBoundaryCollection)

Comapres for inequality. Same as !Equals(PlaneBoundaryCollection).

Declaration

public static bool operator !=(PlaneBoundaryCollection lhs, PlaneBoundaryCollection rhs)

Parameters

Type	Name	Description
PlaneBoundaryCollection	lhs	The left-hand side of the comparison.
PlaneBoundaryCollection	rhs	The right-hand side of the comparison.

Returns

Type	Description
Boolean	true if any of the fields of this PlaneBoundaryCollection are not equal to other.
