Enum Constant Detail

TO_VM

public static final CFunctionOptions.Transition TO_VM

The thread state is transitioned from Java to VM, and the Java parts of the stack are made walkable. If the C code blocks or calls back to Java, it must do an explicit thread state transition to native to prevent that safepoints (and therefore garbage collections) of other threads are delayed.

Method Detail

values

public static CFunctionOptions.Transition[] values()

Returns:

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

valueOf

public static CFunctionOptions.Transition valueOf(String name)

Parameters:

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

Returns:

the enum constant with the specified name

Throws:

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

NullPointerException - if the argument is null
