namespace HashTableSortedColumn

A type-invariant immutable Table of row key type R, column key type C, and value type V. In the Table, a combination of a row and column key has exactly one value. See the Table documentation and the HashTableSortedColumn API documentation

Companion interface: HashTableSortedColumn<R,C,V>

Static Methods

builder

Returns an empty builder instance for this type of collection and context.

Definition

builder<R extends UR, C extends UC, V>(): WithRow<Tp, R, C, V>['builder'];

Type parameters

Name	Constraints	Description
R	UR
C	UC
V

example

HashTableHashColumn.builder<number, string, boolean>()    // => HashTableHashColumn.Builder<number, string, boolean>

Overrides

Factory.builder

createContext

Returns a new HashTableSortedColumn context instance based on the given options.

Definition

createContext<UR, UC>(options?: {
    rowContext?: HashMap.Context<UR>;

  }): HashTableSortedColumn.Context<UR, UC>;

Type parameters

Name	Description
UR	the upper row key type for which the context can create instances
UC	the upper column key type for which the context can create instances

Parameters

Name	Type	Description
options	{     rowContext?: HashMap.Context<UR>;     columnContext?: SortedMap.Context<UC>;   }	(optional) an object containing the following properties: - rowContext: (optional) the map context to use to map row keys to columns - columnContext: (optional) the map context to use to map column keys to values

defaultContext

Returns the default context for HashTableSortedColumns.

Definition

defaultContext<UR, UC>(): HashTableSortedColumn.Context<UR, UC>;

Type parameters

Name	Description
UR	the upper row key type for which the context can create instances
UC	the upper column key type for which the context can create instances

empty

Returns the (singleton) empty instance of this type and context with given key and value types.

Definition

empty<R extends UR, C extends UC, V>(): WithRow<Tp, R, C, V>['normal'];

Type parameters

Name	Constraints	Description
R	UR
C	UC
V

example

HashTableHashColumn.empty<number, string, boolean>()    // => HashTableHashColumn<number, string, boolean>
HashTableHashColumn.empty<string, boolean, number>()    // => HashTableHashColumn<string, boolean, number>

Overrides

Factory.empty

from

Returns an immutable table of this type and context, containing the entries in the given sources StreamSource instances.

Definitions

from<R extends UR, C extends UC, V>(...sources: ArrayNonEmpty<StreamSource.NonEmpty<readonly [R, C, V]>>): WithRow<Tp, R, C, V>['nonEmpty'];

from<R extends UR, C extends UC, V>(...sources: ArrayNonEmpty<StreamSource<readonly [R, C, V]>>): WithRow<Tp, R, C, V>['normal'];

Type parameters

Name	Constraints	Description
R	UR
C	UC
V

Parameters

Name	Type	Description
sources	ArrayNonEmpty<StreamSource.NonEmpty<readonly [R, C, V]>>	an array of StreamSource instances containing row-column-value entries

example

HashTableHashColumn.from([[1, 2, 3], [1, 4, 5]])    // => HashTableHashColumn.NonEmpty<number, number, number>

Overrides

Factory.from

of

Returns an immutable multimap of this collection type and context, containing the given entries.

Definition

of<R extends UR, C extends UC, V>(...entries: ArrayNonEmpty<readonly [R, C, V]>): WithRow<Tp, R, C, V>['nonEmpty'];

Type parameters

Name	Constraints	Description
R	UR
C	UC
V

Parameters

Name	Type	Description
entries	ArrayNonEmpty<readonly [R, C, V]>	a non-empty array of row-column-value entries

example

HashTableHashColumn.of([1, 2, 3], [1, 4, 5])    // => HashTableHashColumn.NonEmpty<number, number, number>

Overrides

Factory.of

reducer

Returns a Reducer that adds received tuples to a Table and returns the Table as a result. When a source is given, the reducer will first create a Table from the source, and then add tuples to it.

Definition

reducer<R extends UR, C extends UC, V>(source?: StreamSource<readonly [R, C, V]>): Reducer<readonly [R, C, V], WithRow<Tp, R, C, V>['normal']>;

Type parameters

Name	Constraints	Description
R	UR
C	UC
V

Parameters

Name	Type	Description
source	StreamSource<readonly [R, C, V]>	(optional) an initial source of tuples to add to

example

const someSource = Table.of([1, 'a', true], [2, 'b', false]);
const result = Stream.of([1, 'c', true], [3, 'a', false]).reduce(Table.reducer(someSource))
result.toArray()   // => [[1, 'c'], [2, 'b'], [3, 'a']]

note

uses a builder under the hood. If the given source is a Table in the same context, it will directly call .toBuilder().

Overrides

Factory.reducer
