Struct ArConfig

Represents the configuration for an ArSession.

Inherited Members
Namespace: UnityEngine.XR.ARCore
Syntax
public struct ArConfig : IEquatable<ArConfig>, IDisposable
Remarks

This is an opaque object that represents a native ArConfig.

Constructors

ArConfig(ArSession)

Creates a new session configuration and initializes it to a sensible default configuration.

Declaration
public ArConfig(ArSession session)
Parameters
Type Name Description
ArSession session

A non-null ArSession.
Remarks

Plane detection and Lighting Estimation are enabled, and blocking update is selected. This configuration is guaranteed to be supported on all devices that support ARCore.

When you no longer need the ArConfig, you should destroy it by calling Dispose(). If you do not dispose it, ARCore will leak memory.

Properties

IsNull

(Read Only) Indicates whether this ArConfig is null. This property is deprecated. Use the equality operator (==) to compare with null instead.

Declaration
[Obsolete("Compare to null instead.")]
public readonly bool IsNull { get; }
Property Value
Type Description
Boolean

Null

Represents a null ArConfig, i.e., one whose underlying native pointer is null. This property is deprecated. Use default instead.

Declaration
[Obsolete("Use default instead.")]
public static readonly ArConfig Null { get; }
Property Value
Type Description
ArConfig

Methods

AsIntPtr()

Gets the underlying native pointer for this ArConfig.

Declaration
public IntPtr AsIntPtr()
Returns
Type Description
IntPtr

Returns the underlying native pointer for this ArConfig.

Dispose()

Destroys this ArConfig and sets the underlying native pointer to null.

Declaration
public void Dispose()
Implements
Remarks

You should only dispose an ArConfig if you explicitly created it, e.g., by calling ArConfig(ArSession). If you convert an existing config from an IntPtr (e.g., by calling FromIntPtr(IntPtr)), then you should not dispose it.

Equals(Object)

Tests for equality.

Declaration
public override bool Equals(object obj)
Parameters
Type Name Description
Object obj

An Object to compare against.
Returns
Type Description
Boolean

Returns true if obj is an ArConfig and it compares equal to this one using Equals(ArConfig).
Overrides

Equals(ArConfig)

Tests for equality.

Declaration
public bool Equals(ArConfig other)
Parameters
Type Name Description
ArConfig other

The ArConfig to compare against.
Returns
Type Description
Boolean

Returns true if the underlying native pointers are the same. Returns false otherwise.
Implements
Remarks

Two ArConfigs are considered equal if their underlying pointers are equal.

FromIntPtr(IntPtr)

Creates an ArConfig from an existing native pointer. The native pointer must point to an existing ArConfig.

Declaration
public static ArConfig FromIntPtr(IntPtr value)
Parameters
Type Name Description
IntPtr value

A pointer to an existing native ArConfig.
Returns
Type Description
ArConfig

Returns an ArConfig whose underlying native pointer is value.

GetHashCode()

Generates a hash code suitable for use with a HashSet or Dictionary

Declaration
public override int GetHashCode()
Returns
Type Description
Int32

Returns a hash code for this ArConfig.
Overrides

Operators

Equality(Nullable<ArConfig>, Nullable<ArConfig>)

Tests for equality.

Declaration
public static bool operator ==(ArConfig? lhs, ArConfig? rhs)
Parameters
Type Name Description
Nullable<ArConfig> lhs

The nullable ArConfig to compare with rhs.
Nullable<ArConfig> rhs

The nullable ArConfig to compare with lhs.
Returns
Type Description
Boolean

Returns true if any of these conditions are met:

  • lhs and rhs are both not null and their underlying pointers are equal.
  • lhs is null and rhs's underlying pointer is null.
  • rhs is null and lhs's underlying pointer is null.
  • Both lhs and rhs are null.

Returns false otherwise.
Remarks

This equality operator lets you to compare an ArConfig with null to determine whether its underlying pointer is null. This allows for a more natural comparison with the native ARCore object: 

bool TestForNull(ArConfig obj)
{
    if (obj == null)
    {
        // obj.AsIntPtr() is IntPtr.Zero
    }
}

Equality(ArConfig, ArConfig)

Tests for equality. Same as Equals(ArConfig).

Declaration
public static bool operator ==(ArConfig lhs, ArConfig rhs)
Parameters
Type Name Description
ArConfig lhs

The ArConfig to compare with rhs.
ArConfig rhs

The ArConfig to compare with lhs.
Returns
Type Description
Boolean

Returns true if lhs is equal to rhs using Equals(ArConfig). Returns false otherwise.

Explicit(ArConfig to IntPtr)

Casts an ArConfig to its underlying native pointer.

Declaration
public static explicit operator IntPtr(ArConfig config)
Parameters
Type Name Description
ArConfig config

The ArConfig to cast.
Returns
Type Description
IntPtr

Returns the underlying native pointer for config

Inequality(Nullable<ArConfig>, Nullable<ArConfig>)

Tests for inequality.

Declaration
public static bool operator !=(ArConfig? lhs, ArConfig? rhs)
Parameters
Type Name Description
Nullable<ArConfig> lhs

The native object to compare with rhs.
Nullable<ArConfig> rhs

The native object to compare with lhs.
Returns
Type Description
Boolean

Returns false if any of these conditions are met:

  • lhs and rhs are both not null and their underlying pointers are equal.
  • lhs is null and rhs's underlying pointer is null.
  • rhs is null and lhs's underlying pointer is null.
  • Both lhs and rhs are null.

Returns true otherwise.
Remarks

This inequality operator lets you to compare an ArConfig with null to determine whether its underlying pointer is null. This allows for a more natural comparison with the native ARCore object: 

bool TestForNull(ArConfig obj)
{
    if (obj != null)
    {
        // obj.AsIntPtr() is not IntPtr.Zero
    }
}

Inequality(ArConfig, ArConfig)

Tests for inequality. Same as the negation of Equals(ArConfig).

Declaration
public static bool operator !=(ArConfig lhs, ArConfig rhs)
Parameters
Type Name Description
ArConfig lhs

The ArConfig to compare with rhs.
ArConfig rhs

The ArConfig to compare with lhs.
Returns
Type Description
Boolean

Returns false if lhs is equal to rhs using Equals(ArConfig). Returns true otherwise.
