Field Detail

MEM

public static final GlobalMemoryAccessor MEM

A GlobalMemoryAccessor that allows both aligned and unaligned native memory access.

MEM_AVAILABLE

public static final boolean MEM_AVAILABLE

If this constant is true, then MEM refers to a usable MemoryAccessor instance.

AMEM

public static final GlobalMemoryAccessor AMEM

Like MEM, but an instance specialized for aligned memory access. Requesting unaligned memory access from this instance will result in low-level JVM crash on platforms which do not support it.

AMEM_AVAILABLE

public static final boolean AMEM_AVAILABLE

If this constant is true, then AMEM refers to a usable MemoryAccessor instance.

Method Detail

getGlobalMemoryAccessor

public static GlobalMemoryAccessor getGlobalMemoryAccessor(GlobalMemoryAccessorType type)

Returns the MemoryAccessor instance appropriate to the given GlobalMemoryAccessorType.

getDefaultGlobalMemoryAccessor

public static GlobalMemoryAccessor getDefaultGlobalMemoryAccessor()

Returns the default GlobalMemoryAccessor instance.
