```
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.
  - setTargetBufferSize
```
public void setTargetBufferSize(int targetBufferSize)
```
    Deprecated.
  - allocate
```
public Allocation allocate()
```
    Deprecated.
    
    Description copied from interface: Allocator
    
    Obtain an Allocation.
    When the caller has finished with the Allocation, it should be returned by calling Allocator.release(Allocation).
    
    Specified by:
    
    allocate in interface Allocator
    
    Returns:
    
    The Allocation.
  - release
```
public void release(Allocation allocation)
```
    Deprecated.
    
    Description copied from interface: Allocator
    
    Releases an Allocation back to the allocator.
    
    Specified by:
    
    release in interface Allocator
    
    Parameters:
    
    allocation - The Allocation being released.
  - release
```
public void release(@Nullable
                    Allocator.AllocationNode allocationNode)
```
    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.

  - getIndividualAllocationLength
```
public int getIndividualAllocationLength()
```
    Deprecated.
    
    Description copied from interface: Allocator
    
    Returns the length of each individual Allocation.
    
    Specified by:
