Returns the additional unparsed data, which should be any number of comma
delimited eMail addresses that follow an existing comma (or semi-colon if a
group construct is being terminated) after the first address that was
provided in the original address string (and will be excluded from this
additional data; there will be no leading comma or semi-colon).
Opens the specified PDF file and attempts to read the Document Properties
from the information section. Returns "true" only if the file's
format conforms to the minimum requirements that make it detectable as a
valid PDF file, regardless of the presence of an information section.
Parses a String array containing a list of options that were provided
by a user or in a configuration file, in the same format and with the same
semantics as Apache's HTTPd server "Options" and "IndexOptions" directives.
Display login prompt, wait for user input, then return a boolean to
indicate success or failure for convenient use within loops (intended for
simplifying the implementation of unsuccessful login retry attempts).
ServerSockets (plural) has many similarities to the java.net.ServerSocket
(singular) class, but it also facilitates binding to multiple endpoints
and provides a simple way to accept() inbound connections simulatenously
without resorting to inefficient CPU/resource-intensive approaches such
as polling or creating an additional thread per binding, etc., each of
which have not been found to scale very well.
Parses a String containing white-space delimited "key=value" pairs, and
returns a String array containing only values that correspond with the
specified key(s), thus consistently placing every value in a specific
position in the array to simplify string parsing, in a flexible manner.
