Constructor Details

Detached

protected Detached(K key,
 Iterable<Cell<?>> cells)

Create a keyed cell collection with given key and cells.

Parameters:

key - the collection key

cells - the contained cells

Method Details

getKey

public K getKey()

Description copied from interface: KeyedCellCollection

Returns the key for this collection.

Specified by:

getKey in interface KeyedCellCollection<K extends Comparable<K>>

Returns:

the collection key

iterator

public Iterator<Cell<?>> iterator()

Specified by:

iterator in interface Collection<K extends Comparable<K>>

Specified by:

iterator in interface Iterable<K extends Comparable<K>>

Specified by:

iterator in class AbstractCollection<Cell<?>>

size

public int size()

Specified by:

size in interface Collection<K extends Comparable<K>>

Specified by:

size in class AbstractCollection<Cell<?>>

get

public <T> Optional<T> get(CellDefinition<T> cellDefinition)

Description copied from interface: CellCollection

Retrieve a cell by CellDefinition. If this record contains a cell whose definition matches the supplied definition (in both name and type) then that cell's value is wrapped in an Optional and returned. If this record contains no matching cell then an empty Optional is returned.

Specified by:

get in interface CellCollection

Type Parameters:

T - the cell JDK type

Parameters:

cellDefinition - cell to retrieve

Returns:

An Optional with the cell value or an empty Optional if the record contains no matching cell

get

public Optional<?> get(String name)

Description copied from interface: CellCollection

Retrieve a cell by name. If this record contains a cell whose definition matches the supplied name then that cell's value is wrapped in an Optional and returned. If this record contains no matching cell then an empty Optional is returned.

Specified by:

get in interface CellCollection

Parameters:

name - cell to retrieve

Returns:

An Optional with the cell value or an empty Optional if the record contains no matching cell

cell

public Optional<Cell<?>> cell(String name)

Description copied from interface: CellCollection

Retrieve a cell by name. If this record contains a cell whose definition matches the supplied name then the cell is wrapped in an Optional and returned. If this record contains no matching cell then an empty Optional is returned.

Specified by:

cell in interface CellCollection

Parameters:

name - cell to retrieve

Returns:

An Optional with the cell or an empty Optional if the record contains no matching cell

contains

public boolean contains(Object o)

Specified by:

contains in interface Collection<K extends Comparable<K>>

Overrides:

contains in class AbstractCollection<Cell<?>>

toString

public String toString()

Overrides:

toString in class AbstractCollection<Cell<?>>

hashCode

public int hashCode()

Description copied from interface: KeyedCellCollection

Returns a hash code value for this collection.

While conforming to the general contract established for Object.hashCode, in concert with #equals, implementations for KeyedCellCollection subclasses will consider the value for getKey and the cells contained in this instance.

Specified by:

hashCode in interface Collection<K extends Comparable<K>>

Specified by:

hashCode in interface KeyedCellCollection<K extends Comparable<K>>

Overrides:

hashCode in class Object

Returns:

a hash code for this instance.

• KeyedCellCollection.equals(Object)

equals

public boolean equals(Object obj)

Description copied from interface: KeyedCellCollection

Indicates whether some object is equal to this KeyedCellCollection.

While conforming to the general contract established for Object.equals, implementations for KeyedCellCollection subclasses will consider the value for getKey and the cells contained in this instance.

Specified by:

equals in interface Collection<K extends Comparable<K>>

Specified by:

equals in interface KeyedCellCollection<K extends Comparable<K>>

Overrides:

equals in class Object

See Also:

• KeyedCellCollection.hashCode()

spliterator

public Spliterator<Cell<?>> spliterator()

Specified by:

spliterator in interface Collection<K extends Comparable<K>>

Specified by:

spliterator in interface Iterable<K extends Comparable<K>>
