public boolean contains(byte e)
ByteContainercontains in interface ByteContainercontains in interface ByteLookupContainertrue if this container has an element equal to
e.public <T extends ByteProcedure> T forEach(T procedure)
ByteContainerprocedure to all container elements. Returns the
argument (any subclass of ByteProcedure. This lets the caller to
call methods of the argument by chaining the call (even if the argument is
an anonymous type) to retrieve computed values, for example (IntContainer):
int count = container.forEach(new IntProcedure() {
int count; // this is a field declaration in an anonymous class.
public void apply(int value) {
count++;
}
}).count;
forEach in interface ByteContainerpublic <T extends BytePredicate> T forEach(T predicate)
ByteContainerpredicate to container elements as long, as the
predicate returns true. The iteration is interrupted
otherwise.forEach in interface ByteContainerpublic boolean isEmpty()

ByteContainer
The iterator is implemented as a cursor and it returns the same cursor
instance on every call to Iterator.next() (to avoid boxing of
primitive types). To read the current list's value (or index in the list)
use the cursor's public fields. An example is shown below.
for (ByteCursor<byte> c : container) {
System.out.println("index=" + c.index + " value=" + c.value);
}
