Recognition: Advanced Topics

10-30 Using Advanced Topics in Recognition

Removing Your RAM-Based Custom Dictionary 10

It is recommended that you remove your custom dictionary when it is no longer

needed, such as when your application is removed. The

DisposeDictionary

function removes a speciﬁed RAM-based dictionary.

The

DisposeDictionary function accepts one argument, the dictionary identiﬁer

returned by

NewDictionary. If this identiﬁer was stored in a slot named

mySpecialDictionary, a line of code similar to the following example would

be used to remove the custom dictionary.

DisposeDictionary(mySpecialDictionary);

Using System Dictionaries Individually 10

The system provides several constants that you can use to refer to system

dictionaries conveniently; see “System-Supplied Dictionaries” (page 8-16) in

Newton Programmer’s Reference. You can set the

vCustomDictionaries ﬂag

and place one or more of these constants in your view’s

dictionaries slot to

specify explicitly the vocabulary it can recognize, such as ﬁrst names only or

names of days and months only. Note that a single constant may represent multiple

dictionaries; for example, when the

kCommonDictionary constant is speciﬁed,

the system may actually add several dictionaries to the set that the view uses for

recognition. The rest of this section describes the use of individual system dictionaries.

The

vNumbersAllowed ﬂag enables both the numeric lexical dictionary and the

monetary lexical dictionary. To create a view that recognizes numeric values but

not monetary values, set the

vCustomDictionaries ﬂag and place the

kNumbersOnlyDictionary constant in the view’s dictionaries slot.

Note that both the

vCustomDictionaries and vCharsAllowed ﬂags enable

text recognition. The difference between these ﬂags is in the set of dictionaries they

enable. The

vCustomDictionaries ﬂag enables only those dictionaries speciﬁed

by the

dictionaries slot of the view performing recognition. The

vCharsAllowed flag, on the other hand, enables several system-supplied

dictionaries. To avoid unexpected results when working with custom dictionaries,

be aware that setting other ﬂags may enable additional dictionaries. Remember,

also, that the printed recognizer can always return words not appearing in dictionaries.

Working With the Review Dictionary 10

The review dictionary object provides methods for manipulating the contents of the

user dictionary (personal word list), and the expand dictionary. Although the

auto-add dictionary is also part of the review dictionary, the auto-add dictionary

has its own interface.
