Class BTree.FastBuilder<V>

  • All Implemented Interfaces:
    java.lang.AutoCloseable
    Enclosing class:
    BTree
    public static class BTree.FastBuilder<V>
extends java.lang.Object
implements java.lang.AutoCloseable
    A pooled builder for constructing a tree in-order, and without needing any reconciliation.

    Constructs whole nodes in place, so that a flush of a complete node can take its buffer entirely. Since we build trees of a predictable shape (i.e. perfectly dense) we do not construct a size map.
