Concatenate two feature sequences.
Concatenate two feature sequences.
The right-argument. Feature values are appended to the result.
A new feature sequence consisting of left-argument followed by the right-argument.
Obtain a new iterator over indices of explicitly-stored feature values.
Obtain a new iterator over indices of explicitly-stored feature values. Equivalent to keysIterator when the feature sequence is dense.
An iterator over indices of explicitly-stored feature values.
Obtain a new iterator over explicitly-stored feature values.
Obtain a new iterator over explicitly-stored feature values. Equivalent to valuesIterator when the feature sequence is dense.
An iterator over explicitly-stored values
The jth element of the feature sequence
The jth element of the feature sequence
element index
The value of jth feature value
The density of explicitly-stored feature values.
The density of explicitly-stored feature values. Defined as the ratio of explicitly-stored values to total length.
The density of explicitly-stored values
Obtain a new iterator over the elements of the feature sequence

An iterator over the feature values
Obtain a new iterator over the indices of the feature sequence.
Obtain a new iterator over the indices of the feature sequence.

The number of feature values in the sequence
(Changed in version 2.9.0) The behavior of scanRight
has changed. The previous behavior can be reproduced with scanRight.reverse.
(Changed in version 2.9.0) transpose
throws an IllegalArgumentException
if collections are not uniformly sized.
