Examples with RemovableSingletonSet net.i2p.router.util.RemovableSingletonSet used on opensource projects

Example 1 with RemovableSingletonSet

use of net.i2p.router.util.RemovableSingletonSet in project i2p.i2p by i2p.

the class TestJob method sendTest.

    // can't tell its a test.  to simplify this, we encrypt it with a random key and tag,

    // garlic encryption without any ElGamal (yay)

the class MessageWrapper method generateSession.
