CX_STRING - Text

CX_STRING

Class hierarchy
Description:

This class is used to display a text of any length. Objects of this class can be created by CreateTransObject(CX_STRING) or CreatePersObject(CX_STRING) . The content is assigned by put. The STRING contained in can be accessed via String.

If an attempt is made to call a method via Call() on a STRING/ML_STRING, then this string is implicitly converted into a temporary CX_STRING object for the Call() , so that all methods mentioned here can be called directly on regular STRINGsand ML_STRINGs(active language). Methods that change the CX_STRING (example: FromBytes) have no effect, because they only work on a temporary copy of the STRING.

Code example: 
Var(logFilePattern) "^.*\.log$" -> logFilePattern

logFilePattern "test.log" Call(Matches) // -> TRUE
logFilePattern "test.txt" Call(Matches) // -> FALSE

"Aa0" Call(GetBytes)                    // -> [ 65 97 48 ]

// To load the ascii bytes into a string we need an actual object
Var(str) CreateTransObject(CX_STRING) -> str
Revert str Call(FromBytes) str          // -> CX_STRING(Aa0)
String                                  // -> "Aa0"

"test" str Put str                      // -> CX_STRING(test)
