If out of range, or this method doesn't work with the given value, FALSE
is returned.
value
Selector for a value for the given property. If out of range, FALSE
is returned.
In general, valid values range from 0 up to some maximum. There are a couple exceptions:
IntlChar::PROPERTY_BLOCK
values begin at the non-zero value IntlChar::BLOCK_CODE_BASIC_LATIN
IntlChar::PROPERTY_CANONICAL_COMBINING_CLASS
values are not contiguous and range from 0..240.
nameChoice
Selector for which name to get. If out of range, FALSE
is returned.
All values have a long name. Most have a short name, but some do not. Unicode allows for additional names;
if present these will be returned by adding 1, 2, etc. to IntlChar::LONG_PROPERTY_NAME
.
Returns the name, or FALSE
if either the property
or the nameChoice
is out of range.
If a given nameChoice
returns FALSE
, then all larger values of nameChoice
will return FALSE
, with one exception: if FALSE
is returned for IntlChar::SHORT_PROPERTY_NAME
,
then IntlChar::LONG_PROPERTY_NAME
(and higher) may still return a non-FALSE
value.
