Instant properties: length
The instant property length represents the length of a string stored within a string operand or the length of vector stored in a point operand.
Declaration
Form 1:
int32 string.length
Form 2:
float point.length
Discussion
In its first form, the read access to this property results in the number of characters stored in a string operand. If the string is empty, the property results in the value 0 (zero). Please note, this property is read-only. The write access to this property is not allowed. For example:
var string s1 = "Hello World!"; var string s2 = ""; // Get the length of the string var int32 result = s1.length; // result = 12 var int32 result = s2.length; // result = 0 // Modification is not allowed s1.length = 10; // Chora compiler error
In its second form, the read access to this property results in the length of a vector specified by the point operand. Please note, this property is read-only. The write access to this property is not allowed. For example:
var point p = <2,1>; var float result = p.length; // result = 2.23606801 // Modification is not allowed p.length = 10; // Chora compiler error
