Method Details

find

default BuildableTypedValueSelectionOptionalFunction<CellCollection> find(String dotSpec)

Construct a potentially portable find function. See ComplexData.find(String) for more info. This call will skip any records which do not have this cell.

Parameters:

dotSpec - find specification

Returns:

Find function

findOrFail

default BuildableTypedValueSelectionFunction<CellCollection> findOrFail(String dotSpec)

Construct a potentially portable find function. See ComplexData.find(String) for more info. This call will throw an exception if any records do not have this cell.

Parameters:

dotSpec - find specification

Returns:

Find function

findOrElse

default BuildableTypedValueSelectionFunction<CellCollection> findOrElse(String dotSpec,
 StoreList otherwise)

Construct a potentially portable find function. See ComplexData.find(String) for more info. If the cell does not exist, the provided StoreMap will be used to evaluate the find against.

Parameters:

dotSpec - find specification

otherwise - alternative if cell is missing.

Returns:

Find function

value

default BuildableListOptionalFunction<CellCollection> value()

Description copied from interface: CellDefinition

Returns a function that extracts the value of this cell from a record.

Specified by:

value in interface CellDefinition<StoreList>

Returns:

a cell extracting function

valueOr

default BuildableListFunction<CellCollection> valueOr(StoreList otherwise)

Description copied from interface: CellDefinition

Returns a function that extracts the value of this cell from a record or uses the given default if the cell is absent.

Specified by:

valueOr in interface CellDefinition<StoreList>

Parameters:

otherwise - default value for absent cells

Returns:

a cell extracting function

valueOrFail

default BuildableListFunction<CellCollection> valueOrFail()

Description copied from interface: CellDefinition

Returns a function that extracts the value of this cell from a record or throws a NoSuchElementException if the cell is absent.

Specified by:

valueOrFail in interface CellDefinition<StoreList>

Returns:

a cell extracting function
