Maven Toolchain Model

 This is the model for Maven toolchain in <<<org.apache.maven.toolchain>>> package,
 delegating content to {{{../../api/maven-api-toolchain/index.html}Maven 4 API immutable toolchain}}. All the effective model
 building logic from multiple toolchains files is done in {{{../maven-toolchain-builder/}Maven Toolchain Builder}}.

 The following are generated from this model:

    eraseAll();
  }

  private ArrayTable(Table<R, C, ? extends @Nullable V> table) {
    this(table.rowKeySet(), table.columnKeySet());
    putAll(table);
  }

  private ArrayTable(ArrayTable<R, C, V> table) {
    rowList = table.rowList;
    columnList = table.columnList;
    rowKeyToIndex = table.rowKeyToIndex;
    columnKeyToIndex = table.columnKeyToIndex;
