Enum Constant Details

TO_NATIVE

public static final CFunction.Transition TO_NATIVE

The thread state is transitioned from Java to C, and the Java parts of the stack are made walkable. The C code can block and call back to Java.

Since:

19.0

NO_TRANSITION

public static final CFunction.Transition NO_TRANSITION

No prologue and epilogue is emitted. The C code must not block and must not call back to Java. Also, long running C code delays safepoints (and therefore garbage collection) of other threads until the call returns.

Since:

19.0

Method Details

values

public static CFunction.Transition[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static CFunction.Transition valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
