ContiguousBlockAllocator (LOCI Javadocs 0-SNAPSHOT API)

java.lang.Object
- de.sciss.jcollider.ContiguousBlockAllocator

All Implemented Interfaces:

BlockAllocator
```
public class ContiguousBlockAllocator
extends Object
implements BlockAllocator
```
Quite a 1:1 translation from the SClang class written by James Harkins, this class is a robust allocator for busses in a dynamic environment. It does not exhibit the fragmentation problem of the PowerOfTwoAllocator.

    Description copied from interface: BlockAllocator
    
    Allocates a new bus.
    
    Specified by:
    
    alloc in interface BlockAllocator
    
    Parameters:
    
    n - the number of channels to allocate. must be greater than zero.
    
    Returns:
    
    the address or index of the bus which is the index of the first channel. returns -1 if the allocator ran out of busses.
