Enum Constant Details

INSTANCE

public static final ParentsVisitor INSTANCE

Method Details

values

public static ParentsVisitor[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static ParentsVisitor valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

getParents

public static Stream<TableSpec> getParents(TableSpec table)

A traversal of the table's parents. Does not perform de-duplication.

Parameters:

table - the table

Returns:

the parents stream

postOrder

public static Set<TableSpec> postOrder(Iterable<TableSpec> tables)

Create a post-order set from tables.

Post-order means that for any given table, the table's dependencies will come before the table itself. There may be multiple valid post-orderings; callers should not rely on a specific post-ordering.

Parameters:

tables - the tables

Returns:

the post-order set

postOrderList

public static List<TableSpec> postOrderList(Iterable<TableSpec> tables)

Create a de-duplicated, post-order list from tables.

Post-order means that for any given table, the table's dependencies will come before the table itself. There may be multiple valid post-orderings; callers should not rely on a specific post-ordering.

Parameters:

tables - the tables

Returns:

the de-duplicated, post-order list

postOrderWalk

public static void postOrderWalk(Iterable<TableSpec> tables,
 Consumer<TableSpec> consumer)

Invoke the consumer for each table in the de-duplicated, post-order walk from tables.

Post-order means that for any given table, the table's dependencies will come before the table itself. There may be multiple valid post-orderings; callers should not rely on a specific post-ordering.

Parameters:

tables - the tables

consumer - the consumer

postOrderWalk

public static void postOrderWalk(Iterable<TableSpec> tables,
 TableSpec.Visitor visitor)

Walk the visitor for each table in the de-duplicated, post-order walk from tables.

Post-order means that for any given table, the table's dependencies will come before the table itself. There may be multiple valid post-orderings; callers should not rely on a specific post-ordering.

Parameters:

tables - the tables

visitor - the visitor

reachable

public static Set<TableSpec> reachable(Iterable<TableSpec> tables)

Create a reachable set from tables, including tables. May be in any order.

Parameters:

tables - the tables

Returns:

the reachable set

search

public static Optional<TableSpec> search(Iterable<TableSpec> initialInputs,
 Predicate<TableSpec> excludePaths,
 Predicate<TableSpec> searchPredicate)

Performs a search for a table that satisfies searchPredicate. Will follow the dependencies of initialInputs. Tables that match excludePaths will not be returned, and will not have its dependencies added to the search.

Note: a dependency of a table that matches excludePaths will be returned if there is any path to that dependency that doesn't go through excludePaths.
