Class NativeHashMapExtensions
NativeHashMap extensions.
Namespace: Unity.Collections
Syntax
public static class NativeHashMapExtensionsMethods
GetBucketData<TKey, TValue>(NativeHashMap<TKey, TValue>)
Returns internal bucked data structure. Internal bucket structure is useful when creating custom jobs operating on container. Each bucket can be processed concurrently with other buckets, and all key/value pairs in each bucket must processed individually (in sequential order) by a single thread.
Declaration
public static UnsafeHashMapBucketData GetBucketData<TKey, TValue>(this NativeHashMap<TKey, TValue> container)
where TKey : struct, IEquatable<TKey> where TValue : structParameters
| Type | Name | Description |
|---|---|---|
| NativeHashMap<TKey, TValue> | container | This container. |
Returns
| Type | Description |
|---|---|
| UnsafeHashMapBucketData | Returns internal bucked data structure. |
Type Parameters
| Name | Description |
|---|---|
| TKey | The type of the keys in the container. |
| TValue | The type of the values in the container. |
GetUniqueKeyArray<TKey, TValue>(UnsafeMultiHashMap<TKey, TValue>, Allocator)
Returns array populated with unique keys.
Declaration
public static (NativeArray<TKey>, int) GetUniqueKeyArray<TKey, TValue>(this UnsafeMultiHashMap<TKey, TValue> container, Allocator allocator)
where TKey : struct, IEquatable<TKey>, IComparable<TKey> where TValue : structParameters
| Type | Name | Description |
|---|---|---|
| UnsafeMultiHashMap<TKey, TValue> | container | This container. |
| Allocator | allocator | A member of the Unity.Collections.Allocator enumeration. |
Returns
| Type | Description |
|---|---|
| ValueTuple<NativeArray<TKey>, Int32> | Unique keys of the container. |
Type Parameters
| Name | Description |
|---|---|
| TKey | The type of the keys in the container. |
| TValue | The type of the values in the container. |
GetUniqueKeyArray<TKey, TValue>(NativeMultiHashMap<TKey, TValue>, Allocator)
Returns array populated with unique keys.
Declaration
public static (NativeArray<TKey>, int) GetUniqueKeyArray<TKey, TValue>(this NativeMultiHashMap<TKey, TValue> container, Allocator allocator)
where TKey : struct, IEquatable<TKey>, IComparable<TKey> where TValue : structParameters
| Type | Name | Description |
|---|---|---|
| NativeMultiHashMap<TKey, TValue> | container | This container. |
| Allocator | allocator | A member of the Unity.Collections.Allocator enumeration. |
Returns
| Type | Description |
|---|---|
| ValueTuple<NativeArray<TKey>, Int32> | Unique keys of the container. |
Type Parameters
| Name | Description |
|---|---|
| TKey | The type of the keys in the container. |
| TValue | The type of the values in the container. |
GetUnsafeBucketData<TKey, TValue>(NativeMultiHashMap<TKey, TValue>)
Returns internal bucked data structure. Internal bucket structure is useful when creating custom jobs operating on container. Each bucket can be processed concurrently with other buckets, and all key/value pairs in each bucket must processed individually (in sequential order) by a single thread.
Declaration
public static UnsafeHashMapBucketData GetUnsafeBucketData<TKey, TValue>(this NativeMultiHashMap<TKey, TValue> container)
where TKey : struct, IEquatable<TKey> where TValue : structParameters
| Type | Name | Description |
|---|---|---|
| NativeMultiHashMap<TKey, TValue> | container | This container. |
Returns
| Type | Description |
|---|---|
| UnsafeHashMapBucketData | Returns internal bucked data structure. |
Type Parameters
| Name | Description |
|---|---|
| TKey | The type of the keys in the container. |
| TValue | The type of the values in the container. |
Remove<TKey, TValue>(NativeMultiHashMap<TKey, TValue>, TKey, TValue)
Removes all elements with the specified key from the container.
Declaration
public static void Remove<TKey, TValue>(this NativeMultiHashMap<TKey, TValue> container, TKey key, TValue value)
where TKey : struct, IEquatable<TKey> where TValue : struct, IEquatable<TValue>Parameters
| Type | Name | Description |
|---|---|---|
| NativeMultiHashMap<TKey, TValue> | container | This container. |
| TKey | key | The key of the element to remove. |
| TValue | value | The value of the element to remove. |
Type Parameters
| Name | Description |
|---|---|
| TKey | The type of the keys in the container. |
| TValue | The type of the values in the container. |
Unique<T>(NativeArray<T>)
Eliminates duplicates from every consecutive group of equivalent elements.
Declaration
public static int Unique<T>(this NativeArray<T> array)
where T : struct, IEquatable<T>Parameters
| Type | Name | Description |
|---|---|---|
| NativeArray<T> | array | Array to perform unique operation on. |
Returns
| Type | Description |
