Member Function Documentation

◆ Claim()

static T Claim ( )

Claim a object.

Returns a pooled object if any are in the pool. Otherwise it creates a new one. After usage, this object should be released using the Release function (though not strictly necessary).

◆ Clear()

static void Clear ( )

Clears the pool for objects of this type.

This is an O(n) operation, where n is the number of pooled objects.

◆ GetSize()

static int GetSize ( )

Number of objects of this type in the pool.

◆ Release()

static void Release ( ref T  obj)

Releases an object.

After the object has been released it should not be used anymore. The variable will be set to null to prevent silly mistakes.

System.InvalidOperationExceptionReleasing an object when it has already been released will cause an exception to be thrown. However enabling ASTAR_OPTIMIZE_POOLING will prevent this check.
