Examples of etch.util.core.nio.History.alloc()

etch.util.core.nio.History.alloc()
Adjusts the number of items actually allocated or freed from some system facility rather than just from a pool. The number of used items can never exceed the number allocated. The number of allocated items equals used plus the current size of the pool. @param k positive if items are being allocated, negative if items arebeing released.

    // newAlloc > limit
    History h = new History( 0, 10, 5 );
    checkUsedAlloc( h, 0, 0 );
    h.alloc( 1 );
    checkUsedAlloc( h, 0, 1 );
    h.alloc( 9 );
    checkUsedAlloc( h, 0, 10 );
    // try to overflow
