An implementation of lazily computed sequences, where elements are stored in "pages", i.e. arrays of fixed size.
A paged sequence is constructed from a function that produces more elements when asked. The producer function - more
, is similar to the read method in java.io.Reader. The more
function takes three parameters: an array of elements, a start index, and an end index. It should try to fill the array between start and end indices (excluding end index). It returns the number of elements produced, or -1 if end of logical input stream was reached before reading any element.
Type parameters
- T
-
the type of the elements contained in this paged sequence, with an
ClassTag
context bound.

Predicate method to check if an element is defined at position index
of the current sequence. Unlike length
this operation does not force reading a lazy sequence to the end.

is larger than its length.

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 typeAny
,x.equals(x)
should returntrue
. - It is symmetric: for any instances
x
andy
of typeAny
,x.equals(y)
should returntrue
if and only ify.equals(x)
returnstrue
. - It is transitive: for any instances
x
,y
, andz
of typeAny
ifx.equals(y)
returnstrue
andy.equals(z)
returnstrue
, thenx.equals(z)
should returntrue
.
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.

Calculate a hash code value for the object.
Calculate 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.
