Constructor Details

SubsetView

protected SubsetView(KeyedCellCollection<K> of,
 Set<CellDefinition<?>> definitions)

Creates a subset view of the given collection showing only the given cells

Parameters:

of - the collection to view

definitions - the cell definitions to select

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

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 CellCollection.SubsetView

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 CellCollection.SubsetView

See Also:

• KeyedCellCollection.hashCode()

subset

public KeyedCellCollection<K> subset(Set<CellDefinition<?>> definitions)

Description copied from interface: CellCollection

Retrieve a subset of cells by their definitions.

The returned collection is a view. If this collection is mutable any mutations performed on this collection will be visible via the returned view.

Specified by:

subset in interface CellCollection

Specified by:

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

Overrides:

subset in class CellCollection.SubsetView

Parameters:

definitions - cells to retrieve

Returns:

a view of a subset of this collection
