Count	The current number of key-value pairs in this hash map.
IsCreated	Whether this hash map has been allocated (and not yet deallocated).
IsEmpty	Whether this hash map is empty.
this[TKey]	Gets and sets values by key.

Methods

Name	Description
Add(TKey, TValue)	Adds a new key-value pair.
AsReadOnly()	Returns a readonly version of this UnsafeHashMap instance.
Clear()	Removes all key-value pairs.
ContainsKey(TKey)	Returns true if a given key is present in this hash map.
Dispose()	Releases all resources (memory).
Dispose(JobHandle)	Creates and schedules a job that will dispose this hash map.
GetEnumerator()	Returns an enumerator over the key-value pairs of this hash map.
GetKeyArray(AllocatorHandle)	Returns an array with a copy of all this hash map's keys (in no particular order).
GetKeyValueArrays(AllocatorHandle)	Returns a NativeKeyValueArrays with a copy of all this hash map's keys and values.
GetValueArray(AllocatorHandle)	Returns an array with a copy of all this hash map's values (in no particular order).
Remove(TKey)	Removes a key-value pair.
TrimExcess()	Sets the capacity to match what it would be if it had been originally initialized with all its entries.
TryAdd(TKey, TValue)	Adds a new key-value pair.
TryGetValue(TKey, out TValue)	Returns the value associated with a key.
