Adds a single element to the builder
Adds a single element to the builder.
the element to be added.
the builder itself.
adds two or more elements to this growable collection
adds two or more elements to this growable collection.

Clears the contents of this builder
Clears the contents of this builder. After execution of this method the builder will contain no elements.
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:
x
of type Any
,
x.equals(x)
should return true
.x
and y
of type
Any
, x.equals(y)
should return true
if and only
if y.equals(x)
returns true
.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)
).
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.
Creates a new builder by applying a transformation function to the results of this builder

the transformation function.
a new builder which is the same as the current builder except that a transformation function is applied to this builder's result.
Produces a collection from the added elements
Produces a collection from the added elements. The builder's contents are undefined after this operation.
Gives a hint how many elements are expected to be added
when the next result
is called
Gives a hint how many elements are expected to be added
when the next result
is called. 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.
Returns a string representation of the object
Returns a string representation of the object.
The default representation is platform dependent.
