Field Detail

JAVA_TIME_MILLIS

public static final HotSpotForeignCallDescriptor JAVA_TIME_MILLIS

JAVA_TIME_NANOS

public static final HotSpotForeignCallDescriptor JAVA_TIME_NANOS

NOTIFY

public static final HotSpotForeignCallDescriptor NOTIFY

NOTIFY_ALL

public static final HotSpotForeignCallDescriptor NOTIFY_ALL

INVOKE_STATIC_METHOD_ONE_ARG

public static final HotSpotForeignCallDescriptor INVOKE_STATIC_METHOD_ONE_ARG

UNSAFE_ARRAYCOPY

public static final ForeignCallSignature UNSAFE_ARRAYCOPY

Signature of an unsafe System.arraycopy(java.lang.Object, int, java.lang.Object, int, int) stub. The signature is equivalent to Unsafe.copyMemory(long, long, long). For the semantics refer to Unsafe.copyMemory(Object, long, Object, long, long).

See Also:

Unsafe.copyMemory(java.lang.Object, long, java.lang.Object, long, long)

GENERIC_ARRAYCOPY

public static final ForeignCallSignature GENERIC_ARRAYCOPY

Signature of a generic System.arraycopy(java.lang.Object, int, java.lang.Object, int, int) stub. Instead of throwing an ArrayStoreException, the stub is expected to return the number of copied elements xor'd with -1. A return value of 0 indicates that the operation was successful.
