replace value by range()

Prev Next

This function searches properties file b for the key a and returns its value.

The keys are interpreted as two values separated by a slash defining a from/to range. If a is within that range (including the boundaries), the search is considered successful. If nothing is found, the default value c will be returned.

The type of the comparison is controlled in parameter d. The following values can be specified.

Compare type

Meaning

withcase

The comparison will be lexical and case-sensitive. a is therefore greater than A (Unicode value).

nocase

The comparison will be lexical and case-insensitive. a is therefore equal to A.

numeric

The comparison will be numeric, i.e. only numbers will be compared. 10 is therefore greater than 2. Note: Non-numeric values are interpreted as 0.

Important note: The order the comparison will take place is coincidental, i.e. the ranges should not overlap.

Parameters

Parameter

Description

a

Key to be searched for in b.

b

Name of the properties file.

c

Default value if the key is not found.

d

(optional) Type of comparison. Default: withcase.

Examples

Note: Please note, in general, with regard to escape characters, the structure of a properties file.

The following properties files are defined.

aaaa/zzzz=lower alpha
AAAA/ZZZZ=upper alpha
0/9=below ten
AAAA/ZZZZ=alphas
0/9=below ten
0/9=below ten
