DefaultAllocator

public DefaultAllocator​(boolean trimOnReset,
                        int individualAllocationSize)

Deprecated.

Constructs an instance without creating any Allocations up front. Parameters:trimOnReset - Whether memory is freed when the allocator is reset. Should be true unless the allocator will be re-used by multiple player instances.individualAllocationSize - The length of each individual Allocation.

DefaultAllocator

public DefaultAllocator​(boolean trimOnReset,
                        int individualAllocationSize,
                        int initialAllocationCount)

Deprecated.

Constructs an instance with some Allocations created up front.

Note: Allocations created up front will never be discarded by trim().

Parameters:trimOnReset - Whether memory is freed when the allocator is reset. Should be true unless the allocator will be re-used by multiple player instances.individualAllocationSize - The length of each individual Allocation.initialAllocationCount - The number of allocations to create up front.

Deprecated.

Description copied from interface: Allocator

Releases all Allocations in the chain starting at the given Allocator.AllocationNode.

Implementations must not make memory allocations.

Specified by:release in interface Allocator

trim

public void trim()

Deprecated.

Description copied from interface: Allocator

Hints to the allocator that it should make a best effort to release any excess Allocations. Specified by:trim in interface Allocator

getTotalBytesAllocated

public int getTotalBytesAllocated()

Deprecated.

Description copied from interface: Allocator

Returns the total number of bytes currently allocated. Specified by:getTotalBytesAllocated in interface Allocator
