C# Class GAudio.GATDataAllocator

Pre-allocates a large float[] to use as virtual memory and avoid any garbage collection. All calls to GATActiveSampleBank and GATReamplingSampleBank GetProcessedSample methods result in a virtual allocation from GATManager's default GATDataAllocator instance.

Méthodes publiques

Méthode	Description
CleanUp ( ) : void
Defragment ( ) : void	Defragments contiguous free chunks. Automatically called when a chunk of appropriate size cannot be recycled.
Dispose ( ) : void
GATDataAllocator ( InitializationSettings initSettings ) : System	Initializes a new instance of the GATDataAllocator class. In most cases, only the default allocator initialized by GATManager is required.
GetDataContainer ( int size ) : GATData	Finds and virtually allocates a GATManagedData instance before returning it as a GATData reference. First, the algorithm looks at the free chunks bin of appropriate size. If the bin doesn't hold any chunk, it will check if there is enough unfragmented space. If there isn't, it will look at bins holding larger chunks and fragment one if found. Finally, it will attempt defragmenting and run again, before logging an out of memory error.
GetDebugInfo ( ) : List	Gets information regarding each allocated chunk.
GetFixedDataContainer ( int size, string description ) : GATData	Allocates a fixed chunk of memory. Fixed chunks cannot be freed, but may be of any size. For debugging ease, a description is required when requesting a fixed chunk.
GetFixedDebugInfo ( ) : List	Gets information regarding fixed allocations.
NbOfAvailableChunksForSize ( int size ) : int	A conservative estimate of the available number of chunks. Takes into account both unfragmented memory and recyclable previously allocated chunks.

GetDataContainer() public méthode

Finds and virtually allocates a GATManagedData instance before returning it as a GATData reference. First, the algorithm looks at the free chunks bin of appropriate size. If the bin doesn't hold any chunk, it will check if there is enough unfragmented space. If there isn't, it will look at bins holding larger chunks and fragment one if found. Finally, it will attempt defragmenting and run again, before logging an out of memory error.
