Returns:

a string length function

startsWith

default BuildablePredicate<T> startsWith(String prefix)

Returns a predicate that tests the strings generated by this to see if they start with the supplied constant string. If this is a function that generates an empty Optional, the returned predicate would always evaluate to false

Parameters:

prefix - constant prefix string
