Example 1 with AllocatorImpl

use of suite.file.impl.AllocatorImpl in project suite by stupidsing.

the class B_TreeBuilder method build.

private B_Tree<Key, Value> build(Comparator<Key> comparator, PageFile alf0, PageFile sbf0, PageFile pf0) {
    B_TreeImpl<Key, Value> b_tree = new B_TreeImpl<>(Object_.nullsFirst(comparator));
    Serializer<Bytes> als = serialize.bytes(pageSize);
    B_TreeSuperblockSerializer sbs = new B_TreeSuperblockSerializer(b_tree);
    Serializer<Bytes> pys = serialize.bytes(pageSize);
    B_TreePageSerializer ps = new B_TreePageSerializer(b_tree);
    SerializedPageFile<Bytes> alf = SerializedFileFactory.serialized(alf0, als);
    SerializedPageFile<B_TreeImpl<Key, Value>.Superblock> sbf = SerializedFileFactory.serialized(sbf0, sbs);
    SerializedPageFile<Bytes> pyf = SerializedFileFactory.serialized(pf0, pys);
    SerializedPageFile<B_TreeImpl<Key, Value>.Page> pf = SerializedFileFactory.serialized(pf0, ps);
    b_tree.setAllocator(new AllocatorImpl(alf));
    b_tree.setSuperblockPageFile(sbf);
    b_tree.setPayloadFile(pyf);
    b_tree.setPageFile(pf);
    b_tree.setBranchFactor(16);
    return b_tree;
}

Example 2 with AllocatorImpl

use of suite.file.impl.AllocatorImpl in project suite by stupidsing.

the class B_TreeBuilder method build.

public B_Tree<Key, Value> build(PageFile f, int nPages, Comparator<Key> cmp) {
    var nSuperblockPages = 1;
    var nAllocatorPages = nPages / pageSize;
    var p0 = 0;
