|---|---|
boolean |
applies(Predicate<? super V> predicate)
Tests each element of the collection on the given predicate.
|
V |
at(long index) |
boolean |
contains(V value)
Checks if the given element is contained in the collection.
|
boolean |
containsAll(XGettingCollection<? extends V> values) |
boolean |
containsId(V value)
Special version of contains() that guarantees to use identity comparison (" == ") when searching for the
given element regardless of the collection's internal logic.
This method has the same behavior as XGettingCollection.containsSearched(Predicate) with a Predicate implementation
that checks for object identity. |
boolean |
containsSearched(Predicate<? super V> predicate) |
XImmutableList<V> |

at the time the method is called.

Iterates through all the elements of the given indices and calls the
Consumer.accept(Object) on the target Consumer. |

copyTo(T target)
Calls
Consumer.accept(Object) on the target Consumer for all the elements of this collection. |

using the
Equalator. |

Count how many matches are found using the given predicate on each element of the collection.
|
<T extends Consumer<? super V>> |
distinct(T target)
Calls
Consumer.accept(Object) on the target Consumer for all the unique/distinct
elements of this collection. |

Consumer.accept(Object) on the target Consumer for all the unique/distinct
elements of this collection. |

boolean |
equals(XGettingCollection<? extends V> samples,

Returns
true if all elements of this list and the passed list are sequentially equal as defined
by the passed equalator. |

except(XGettingCollection<? extends V> other,
Equalator<? super V> equalator,
T target)

Consumer.accept(Object) on the target Consumer for each
element of this collection that is not contained in the other collection (through the given equalator). |

Predicate<? super V> predicate)
Calls
Consumer.accept(Object) on the target Consumer for all the elements of this collection
which test true on the given predicate. |

first()
Gets first element or throws
IndexOutOfBoundsException if the collection is empty. |
V |
get()
Gets one element from the collection.
|
boolean |
hasVolatileElements()
Tells if this collection contains volatile elements.
An element is volatile, if it can become no longer reachable by the collection without being removed from the collection. |

Tests if the collection is sorted according to the given comparator.
|

Note that for colletion types that don't have a defined order of elements, this method is hardly usable
(as is XGettingCollection.equals(Object) for them as defined in Collection). The core problem of comparing
collections that have no defined order is that they aren't really reliably comparable to any other collection.
