Method Details

itemClass

public Class<C> itemClass()

Returns:

the Class of the items in this List

first

public Optional<C> first()

Returns:

an Optional of the first OnixComposite listed, if any

firstOrEmpty

public C firstOrEmpty()

Returns:

the first OnixComposite listed, if any, or an "empty" instance (whose OnixTag.exists() is false), which can be further traversed by your code (as if it exists in the ONIX source), with all underlying data fields eventually yielding "non-existing" value

filter

public ListOfOnixComposite<C> filter(Predicate<C> predicate)

Given this list of OnixComposites, this method creates a new list containing only a subset of items, or none, conforming to the condition passed in the Predicate object.

Note that this method is different from .stream().filter() in that it returns a list of the same original type (i.e. ListOfOnixComposite), and not a generic Java List. This allows the caller to apply methods such as firstOrEmpty() on the returned list.

Returns:

a non-null, possibly empty, sublist of items meeting the predicate condition
