GLOSSARY

GL-2

cursor An object returned by the Query

method. The cursor contains methods that iterate

over a set of soup entries meeting the criteria

speciﬁed in the query. The addition or deletion

of entries matching the query speciﬁcation is

automatically reﬂected in the set of entries

referenced by the cursor, even if the changes

occur after the original query was made.

data deﬁnition A frame containing slots that

deﬁne a particular type of data and the methods

that operate on it. The entries deﬁned are used

by an application and stored in its soup. A data

deﬁnition is registered with the system. The

shortened term dataDef is sometimes used. See

also view deﬁnition.

data form A symbol that describes the

transformations that must occur when data is

exchanged with other environments. When you

send data or set endpoint options, the data form

deﬁnes how to convert the data from its

NewtonScript format. When you receive data or

get endpoint options, the data form deﬁnes the

type of data expected.

declaring a template Registering a template

in another view (usually its parent) so that the

template’s view is preallocated when the other

view is opened. This allows access to methods

and slots in the declared view.

deferred recognition The process of

recognizing an ink word that was drawn by the

user at an earlier time. Deferred recognition is

usually initiated when the user double-taps on

an ink word. See also ink and ink word.

desktop computer Either a Mac OS or

Windows-based computer. Sometimes called

simply “desktop.”

emporium The permanent internal

descriptions of places the user works with the

Newton PDA. (Home and Ofﬁce are obvious

examples, but so might be “Tokyo Ofﬁce” if the

user travels a lot.) Choosing an emporium sets

up information such as local area code, dialing

preﬁxes, time zone, and so on. This term is

sometimes called “locale.” The plural

is “emporia.”

endpoint An object created from

protoBasicEndpoint, or one of its

derivative protos, that controls a real-time

communication session. This object

encapsulates and maintains the details of the

speciﬁc connection, and allows you to control

the underlying communication tool.

endpoint option An endpoint option is

speciﬁed in a frame passed in an array as an

argument to one of the endpoint methods.

Endpoint options select the communication tool

to use, control its conﬁguration and operation,

and return result code information from each

endpoint method call.

entry A frame stored in a soup and accessed

through a cursor. An entry frame contains

special slots that identify it as belonging to a

soup.

entry alias An object that provides a standard

way to save a reference to a soup entry. Entry

aliases themselves may be stored in soups.

enumerated dictionary A list of words that

can be recognized when this dictionary is

enabled. See also lexical dictionary.

EOP End of packet indicator.

evaluate slot A slot that’s evaluated when

NTK (Newton Toolkit) compiles the application.

event An entry in the Dates application for a

day, but not a particular time during that day.

ﬁeld An area in a view where a user can write

information.

ﬁnder A frame containing methods and/or

objects that enumerate data items found to

match criteria speciﬁed via the Find slip.
