def equals(arg0: Any): Boolean

This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence
This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence.
The default implementations of this method is an equivalence relation:
- It is reflexive: for any instance x of type Any, x.equals(x) should return true.
- It is symmetric: for any instances x and y of type Any, x.equals(y) should return true if and only if y.equals(x) returns true.
- It is transitive: for any instances x, y, and z of type AnyRef if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
If you override this method, you should verify that your implementation remains an equivalence relation. Additionally, when overriding this method it is often necessary to override hashCode to ensure that objects that are "equal" (o1.equals(o2) returns true) hash to the same Int (o1.hashCode.equals(o2.hashCode)).
arg0
the object to compare against this object for equality.
returns
true if the receiver object is equivalent to the argument; false otherwise.

def hasDefiniteSize: Boolean

Tests whether this iterable collection is known to have a finite size

Tests whether this iterable collection is known to have a finite size. All strict collections are known to have finite size. For a non-strict collection such as Stream, the predicate returns true if all elements have been computed. It returns false if the stream is not yet evaluated to the end.

def hashCode(): Int

Returns a hash code value for the object

Returns a hash code value for the object.
The default hashing algorithm is platform dependent.
Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)) yet not be equal (o1.equals(o2) returns false). A degenerate implementation could always return 0. However, it is required that if two objects are equal (o1.equals(o2) returns true) that they have identical hash codes (o1.hashCode.equals(o2.hashCode)). Therefore, when overriding this method, be sure to verify that the behavior is consistent with the equals method.

def unzip[A1, A2](asPair: (B) ⇒ (A1, A2)): (Iterable[A1], Iterable[A2])

Converts this iterable collection of pairs into two collections of the first and second halfs of each pair

Converts this iterable collection of pairs into two collections of the first and second halfs of each pair.

asPair
an implicit conversion which asserts that the element type of this iterable collection is a pair.

def view(from: Int, until: Int): IterableView[B, IterableView[B, Coll]]

Creates a non-strict view of a slice of this iterable collection

Creates a non-strict view of a slice of this iterable collection.
Note: the difference between view and slice is that view produces a view of the current iterable collection, whereas slice produces a new iterable collection.
Note: view(from, to) is equivalent to view.slice(from, to)
Note: might return different results for different runs, unless the underlying collection type is ordered.

from
the index of the first element of the view
until
the index of the element following the view
returns
a non-strict view of a slice of this iterable collection, starting at index from and extending up to (but not including) index until.

def withFilter(p: (B) ⇒ Boolean): WithFilter

Creates a non-strict filter of this iterable collection

Creates a non-strict filter of this iterable collection.
Note: the difference between c filter p and c withFilter p is that the former creates a new collection, whereas the latter only restricts the domain of subsequent map, flatMap, foreach, and withFilter operations.
Note: might return different results for different runs, unless the underlying collection type is ordered.

p
the predicate used to test elements.
returns
an object of class WithFilter, which supports map, flatMap, foreach, and withFilter operations. All these operations apply to those elements of this iterable collection which satify the predicate p.

def zip[A1 >: B, B, That](that: Iterable[B])(bf: CanBuildFrom[IterableView[B, Coll], (A1, B), That]): That

Returns a iterable collection formed from this iterable collection and another iterable collection by combining corresponding elements in pairs

Returns a iterable collection formed from this iterable collection and another iterable collection by combining corresponding elements in pairs. If one of the two collections is longer than the other, its remaining elements are ignored.
Note: might return different results for different runs, unless the underlying collection type is ordered.

A1
the type of the first half of the returned pairs (this is always a supertype of the collection's element type A).
B
the type of the second half of the returned pairs
That
the class of the returned collection. Where possible, That is the same class as the current collection class Repr, but this depends on the element type (A1, B) being admissible for that class, which means that an implicit instance of type CanBuildFrom[Repr, (A1, B), That]. is found.
that
The iterable providing the second half of each result pair
bf
an implicit value of class CanBuildFrom which determines the result class That from the current representation type Repr and the new element type (A1, B).
returns
a new collection of type That containing pairs consisting of corresponding elements of this iterable collection and that. The length of the returned collection is the minimum of the lengths of this iterable collection$ and that.

def zipAll[B, A1 >: B, That](that: Iterable[B], thisElem: A1, thatElem: B)(bf: CanBuildFrom[IterableView[B, Coll], (A1, B), That]): That

Returns a iterable collection formed from this iterable collection and another iterable collection by combining corresponding elements in pairs

Returns a iterable collection formed from this iterable collection and another iterable collection by combining corresponding elements in pairs. If one of the two collections is shorter than the other, placeholder elements are used to extend the shorter collection to the length of the longer.
Note: might return different results for different runs, unless the underlying collection type is ordered.

that
the iterable providing the second half of each result pair
thisElem
the element to be used to fill up the result if this iterable collection is shorter than that.
thatElem
the element to be used to fill up the result if that is shorter than this iterable collection.
returns
a new collection of type That containing pairs consisting of corresponding elements of this iterable collection and that. The length of the returned collection is the maximum of the lengths of this iterable collection$ and that. If this iterable collection is shorter than that, thisElem values are used to pad the result. If that is shorter than this iterable collection, thatElem values are used to pad the result.

def zipWithIndex[A1 >: B, That](bf: CanBuildFrom[IterableView[B, Coll], (A1, Int), That]): That

Zips this iterable collection with its indices

Zips this iterable collection with its indices.
Note: might return different results for different runs, unless the underlying collection type is ordered.

A1
the type of the first half of the returned pairs (this is always a supertype of the collection's element type A).
That
the class of the returned collection. Where possible, That is the same class as the current collection class Repr, but this depends on the element type (A1, Int) being admissible for that class, which means that an implicit instance of type CanBuildFrom[Repr, (A1, Int), That]. is found.
returns
A new collection of type That containing pairs consisting of all elements of this iterable collection paired with their index. Indices start at 0.
