StringItem

Method	Description	Example
truthy?	Item state not UNDEF, not NULL and is not blank (‘’) when trimmed.	`puts "#{item.name} is truthy" if item.truthy?`
String methods*	All methods for Ruby String	`StringOne << StringOne + ' World!'`
blank?	True if state is UNDEF, NULL, string is empty or contains only whitespace	`StringOne << StringTwo unless StringTwo.blank?`

All String methods returns a copy of the current state as a string. Methods that modify a string in place, do not modify the underlying state string.

Examples

String operations can be performed directly on the StringItem

# StringOne has a current state of "Hello"
StringOne << StringOne + " World!"
# StringOne will eventually have a state of 'Hello World!'

# Add Number item to 5
NumberOne << 5 + NumberOne

String Items can be selected in an enumerable with grep.

# Get all StringItems
items.grep(StringItem)
     .each { |string| logger.info("#{string.id} is a String Item") }

String Item values can be matched against regular expressions

# Get all Strings that start with an H
Strings.grep(/^H/)
        .each { |string| logger.info("#{string.id} starts with an H") }
