Testing Formatted Strings

The following functions are available for testing formatted string fields:

Function	Description
trim(String s)	Returns a copy of s, with leading and trailing white space omitted.
truncate(String s, int n)	Returns the first n-3 characters of the s with "…" appended. The total length of the returned string is n.
concat(String s1, String s2)	Returns a string that concatenates s2 to the end of s1.
substring(String s, int beginIndex, int endIndex)	Returns a new string that is a substring of this string. The substring begins at the specified beginIndex and extends to the character at index endIndex- 1. Thus the length of the substring is endIndex - beginIndex.
toUpperCase(String s)	Converts all of the characters of s to upper case.
toLowerCase(String s)	Converts all of the characters of s to lower case.
toTitleCase(String s)	Converts all of the characters of s to title case.
toPlural(String s)	Converts s to be plural by adding the character ‘s’ unless s ends in ‘s’ in which case ‘es’ is added.
escapeQuotes(String s)	Replaces "\’" with "\\\’" in s.
replace(String s, String old, String new)	Replaces all occurrences of old in the string s, with new.

Examples:

<t:if test="toUpperCase('help')=='HELP'">toUpperCase success</t:if>

<t:if test="toLowerCase('HELP')=='help'">toLowerCase success</t:if>

<t:if test="toTitleCase('title')=='Title'">toTitleCase success</t:if>

<t:if test="toPlural('grow')=='grows'">toPlural success (s)</t:if>

<t:if test="toPlural('class')=='classes'">toPlural success (es)</t:if>

<t:if test="getDefault('','default')=='default'">getDefault success</t:if>

<t:if test="escapeQuotes('\'')=='\\\''">escapeQuotes success</t:if>

<t:if test="replace('Freely','ly','dom')=='Freedom'">replace success</t:if>

<t:if test="concat('Con','vio')=='Convio'">concat success</t:if>

<t:if test="substring('getactive', 3, 4)=='a'">substring success</t:if>

<t:if test="trim(' gooo ') == 'gooo'">trim success</t:if>

<t:if test="truncate('Alpahnumern',5)=='Al...'">truncate success</t:if>
