26 * Abstraction of the regular expressions used to validate attribute values.
27 *
28 The validationPattern element defines the allowable character-level
29 or field-level values for an attribute.
30
31 JSTL: validationPattern is a Map which is accessed using a key
32 of "validationPattern". Each entry may contain some of the keys
33 listed below. The keys that may be present for a given attribute
34 are dependent upon the type of validationPattern.
35
36 * maxLength (String)
37 * exactLength
38 * type
39 * allowWhitespace
40 * allowUnderscore
41 * allowPeriod
42 * validChars
43 * precision
44 * scale
45 * allowNegative
46
47 The allowable keys (in addition to type) for each type are:
48 ****Type**** ***Keys***
49 alphanumeric exactLength
50 maxLength
51 allowWhitespace
52 allowUnderscore
53 allowPeriod
54
55 alpha exactLength
56 maxLength
57 allowWhitespace
58
59 anyCharacter exactLength
60 maxLength
61 allowWhitespace
62
63 charset validChars
64
65 numeric exactLength
66 maxLength
67
68 fixedPoint allowNegative
69 precision
70 scale
71
72 floatingPoint allowNegative
73
74 date n/a
75 emailAddress n/a
76 javaClass n/a
77 month n/a
78 phoneNumber n/a
79 timestamp n/a
80 year n/a
81 zipcode n/a
82
83 Note: maxLength and exactLength are mutually exclusive.
84 If one is entered, the other may not be entered.
85
86 Note: See ApplicationResources.properties for
87 exact regex patterns.
88 e.g. validationPatternRegex.date for regex used in date validation.
