Text predicates

Reference documentation for Expressif predicates in the text scope.

Name	Overview
`contains`	Returns `true` if the value passed as argument contains, anywhere in the string, the text value passed as parameter. Returns `false` otherwise.
`ends-with`	Returns `true` if the value passed as argument ends with the text value passed as parameter. Returns `false` otherwise.
`is-any-of`	Returns `true` if the list of text values passed as parameter contains the text value passed as argument. Returns `false` otherwise.
`is-empty`	Returns `true` if argument value has a length of `0`. Return `false` otherwise.
`is-empty-or-null`	Returns `true` if argument value has a length of `0` or is `null`. Return `false` otherwise.
`is-equivalent-to`	Compare the text value passed as argument and the text value passed as parameter and returns `true` if they are equal. By default the comparison is agnostic of the culture and case-insensitive.
`is-lower-case`	Returns `true` if all characters of the text value passed as argument are lower-case. The value `null`, `empty` and `whitespace` also returns `true`. Returns `false` otherwise.
`is-sorted-after`	Compare the text value passed as argument and the text value passed as parameter and returns `true` if argument value is alphabetically sorted after the parameter value. By default the comparison is agnostic of the culture and case-insensitive.
`is-sorted-after-or-equivalent-to`	Compare the text value passed as argument and the text value passed as parameter and returns `true` if argument value is alphabetically sorted after the parameter value or if the two values are equal. By default the comparison is agnostic of the culture and case-insensitive.
`is-sorted-before`	Compare the text value passed as argument and the text value passed as parameter and returns `true` if argument value is alphabetically sorted before the parameter value. By default the comparison is agnostic of the culture and case-insensitive.
`is-sorted-before-or-equivalent-to`	Compare the text value passed as argument and the text value passed as parameter and returns `true` if argument value is alphabetically sorted before the parameter value or if the two values are equal. By default the comparison is agnostic of the culture and case-insensitive.
`is-upper-case`	Returns `true` if all characters of the text value passed as argument are upper-case. The value `null`, `empty` and `whitespace` also returns `true`. Returns `false` otherwise.
`matches-date`	Returns `true` if the text value passed as argument is a valid representation of a date in the culture specified as parameter. If the value is of type `DateTime` and the time part is set to midnight then it returns `true`. If the value is of type `Date`. Returns `false` otherwise.
`matches-datetime`	Returns `true` if the text value passed as argument is a valid representation of a dateTime in the culture specified as parameter. The expected format is the concatenation of the ShortDatePattern, a space and the LongTimePattern. If the value is of type `DateTime`, it returns `true`. Returns `false` otherwise.
`matches-numeric`	Returns `true` if the text value passed as argument is a valid representation of a numeric in the culture specified as parameter. Returns `false` otherwise.
`matches-regex`	Returns `true` if the value passed as argument validate the regex passed as parameter. Returns `false` otherwise.
`matches-time`	Returns `true` if the text value passed as argument is a valid representation of a time in the culture specified as parameter. The expected format is the LongTimePattern. If the value is of type `TimeOnly`, it returns `true`. Returns `false` otherwise.
`starts-with`	Returns `true` if the value passed as argument starts with the text value passed as parameter. Returns `false` otherwise.
