Example 47 with Field

use of com.oracle.truffle.espresso.impl.Field in project graal by oracle.

the class Target_sun_misc_Unsafe method park.

/**
 * Block current thread, returning when a balancing <tt>unpark</tt> occurs, or a balancing
 * <tt>unpark</tt> has already occurred, or the thread is interrupted, or, if not absolute and
 * time is not zero, the given time nanoseconds have elapsed, or if absolute, the given deadline
 * in milliseconds since Epoch has passed, or spuriously (i.e., returning for no "reason").
 * Note: This operation is in the Unsafe class only because <tt>unpark</tt> is, so it would be
 * strange to place it elsewhere.
