Compares the receiver object (this) with the argument object (that) for equivalence.
Compares the receiver object (this) with the argument object (that) for equivalence.
Any implementation of this method should be 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 Any 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 usually necessary to override hashCode to ensure that objects which are "equal" (o1.equals(o2) returns true) hash to the same scala.Int. (o1.hashCode.equals(o2.hashCode)).
Value parameters
- that
-
the object to compare against this object for equality.

- Returns

Produces a collection from the added elements.
Produces a collection from the added elements.
After a call to result, the behavior of all other methods is undefined save for clear(). If clear() is called, then the builder is reset and may be used to build another instance.
Attributes
- Returns
-
a collection containing the elements added to this builder.

Returns a string representation of the object.
Returns a string representation of the object.
The default representation is platform dependent.

Adds all elements produced by an IterableOnce to this growable collection.
Adds all elements produced by an IterableOnce to this growable collection.
Value parameters
- elems
-
the IterableOnce producing the elements to add.

Add a slice of an array.
Add all elements of an array.
Clears the contents of this builder.
Clears the contents of this builder. After execution of this method, the builder will contain no elements.
If executed immediately after a call to result(), this allows a new instance of the same type of collection to be built.

Gives a hint how many elements are expected to be added in total by the time result is called.
Gives a hint how many elements are expected to be added in total by the time result is called.
Some builder classes will optimize their representation based on the hint. However, builder implementations are required to work correctly even if the hint is wrong, e.g., a different number of elements is added, or the hint is out of range.
The default implementation simply ignores the hint.
Value parameters
- size
-
the hint how many elements will be added.

Gives a hint that the result of this builder is expected to have the same size as the given collection, plus some delta.
Gives a hint that the result of this builder is expected to have the same size as the given collection, plus some delta.
This method provides a hint only if the collection has a known size, as specified by the following pseudocode:
if (coll.knownSize != -1)
if (coll.knownSize + delta <= 0) sizeHint(0)
else sizeHint(coll.knownSize + delta)
If the delta is negative and the result size is known to be negative, then the size hint is issued at zero.
Some builder classes will optimize their representation based on the hint. However, builder implementations are required to work correctly even if the hint is wrong, i.e., if a different number of elements is added.
Value parameters
- coll
-
the collection which serves as a hint for the result's size.
- delta
-
a correction to add to the
coll.sizeto produce the size hint (zero if omitted).

Gives a hint how many elements are expected to be added when the next result is called, together with an upper bound given by the size of some other collection.
Gives a hint how many elements are expected to be added when the next result is called, together with an upper bound given by the size of some other collection. Some builder classes will optimize their representation based on the hint. However, builder implementations are still required to work correctly even if the hint is wrong, i.e. a different number of elements is added.
Value parameters
- boundingColl
-
the bounding collection. If it is an IndexedSeqLike, then sizes larger than collection's size are reduced.
- size
-
the hint how many elements will be added.
