endsWith
String ::endsWith (match : String ) : Boolean
Returns true if the String terminates with the match String provided as an
argument. Following is an example of an assertion that looks for sentences end-
ing without a period and logs a warning if found:
var sentence : String := 'I end without a period';
assert warning (sentence.endsWith('.'))
with log ('Sentence ends without a period', sentence);
startsWith
String ::startsWith (match : String ) : Boolean
Returns true if the String begins with the match String provided as an argu-
ment. Following is an example of an assertion that looks for sentences beginning
with whitespace and logs a warning if found:
var sentence : String := ' I start with a space.';
assert warning ( not sentence.startsWith(' '))
with log ('Sentence starts with a space', sentence);
trim
String ::trim () : String
Returns a String with leading and trailing whitespace removed. Note that the
sentence variable in the previous startsWith() example could be corrected
using trim() :
sentence.trim();
normalizeSpace
String ::normalizeSpace() : String
