Struct NativeReference<T>

An unmanaged, reference container.

Namespace: Unity.Collections
Syntax
public struct NativeReference<T> : INativeDisposable, IDisposable, IEquatable<NativeReference<T>> where T : struct
Type Parameters
Name Description
T

The type of the reference in the container.

Constructors

NativeReference(T, Allocator)

Constructs a new reference container using the specified type of memory allocation, and initialize it to specific value.

Declaration
public NativeReference(T value, Allocator allocator)
Parameters
Type Name Description
T value

The value of this container.
Allocator allocator

A member of the Unity.Collections.Allocator enumeration.

NativeReference(Allocator, NativeArrayOptions)

Constructs a new reference container using the specified type of memory allocation.

Declaration
public NativeReference(Allocator allocator, NativeArrayOptions options = null)
Parameters
Type Name Description
Allocator allocator

A member of the Unity.Collections.Allocator enumeration.
NativeArrayOptions options

A member of the Unity.Collections.NativeArrayOptions enumeration.

Properties

IsCreated

Determine whether or not this container is created.

Declaration
public bool IsCreated { get; }
Property Value
Type Description
Boolean
Remarks

Warning: the IsCreated property can't be used to determine whether a copy of a container is still valid. If you dispose any copy of the container, the container storage is deallocated. However, the properties of the other copies of the container (including the original) are not updated. As a result the IsCreated property of the copies still return true even though the container storage has been deallocated. Accessing the data of a native container that has been disposed throws a exception.

Value

The value of this container.

Declaration
public T Value { get; set; }
Property Value
Type Description
T

Methods

AsReadOnly()

Retrieve this container as read-only.

Declaration
public NativeReference<T>.ReadOnly AsReadOnly()
Returns
Type Description
NativeReference.ReadOnly<>

A read-only reference container.

Copy(NativeReference<T>, NativeReference<T>)

Copy source container to destination container.

Declaration
public static void Copy(NativeReference<T> dst, NativeReference<T> src)
Parameters
Type Name Description
NativeReference<T> dst

The destination reference.
NativeReference<T> src

The source reference.

CopyFrom(NativeReference<T>)

Copy this container from another container.

Declaration
public void CopyFrom(NativeReference<T> reference)
Parameters
Type Name Description
NativeReference<T> reference

The container to copy from.

CopyTo(NativeReference<T>)

Copy this container to another container.

Declaration
public void CopyTo(NativeReference<T> reference)
Parameters
Type Name Description
NativeReference<T> reference

The container to copy to.

Dispose()

Disposes of this container and deallocates its memory immediately.

Declaration
public void Dispose()

Dispose(JobHandle)

Safely disposes of this container and deallocates its memory when the jobs that use it have completed.

Declaration
public JobHandle Dispose(JobHandle inputDeps)
Parameters
Type Name Description
JobHandle inputDeps

The job handle or handles for any scheduled jobs that use this container.
Returns
Type Description
JobHandle

A new job handle containing the prior handles as well as the handle for the job that deletes the container.
Implements
Remarks

You can call this function dispose of the container immediately after scheduling the job. Pass the JobHandle returned by the Job.Schedule method using the jobHandle parameter so the job scheduler can dispose the container after all jobs using it have run.

Equals(Object)

Determine whether this object is equal to another object of the same type.

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

An object to compare with this object.
Returns
Type Description
Boolean

true if this object is equal to the obj parameter, otherwise false.

Equals(NativeReference<T>)

Determine whether this container is equal to another container.

Declaration
public bool Equals(NativeReference<T> other)
Parameters
Type Name Description
NativeReference<T> other

A container to compare with this container.
Returns
Type Description
Boolean

true if this container is equal to the other parameter, otherwise false.

GetHashCode()

Returns the hash code for this container.

Declaration
public override int GetHashCode()
Returns
Type Description
Int32

A 32-bit signed integer hash code.

Operators

Equality(NativeReference<T>, NativeReference<T>)

Declaration
public static bool operator ==(NativeReference<T> left, NativeReference<T> right)
Parameters
Type Name Description
NativeReference<T> left

Left-hand side container.
NativeReference<T> right

Right-hand side container.
Returns
Type Description
Boolean

true if left parameter is equal to the right parameter, otherwise false.

Inequality(NativeReference<T>, NativeReference<T>)

Determine whether a container is not equal to another container.

Declaration
public static bool operator !=(NativeReference<T> left, NativeReference<T> right)
Parameters
Type Name Description
NativeReference<T> left

Left-hand side container.
NativeReference<T> right

Right-hand side container.
Returns
Type Description
Boolean

true if left parameter is not equal to the right parameter, otherwise false.
