Description

These types and functions are builtin and do not require any use statement.

Type details

type Any;

Parent type of all other types.

type Byte < Any;

Byte value. Values of this type are signed integer numbers in range from −128 to 127.

type Short < Any;

Short integer value. Values of this type are signed integer numbers in range from −32768 to 32767.

type Char < Any;

Character value. Values of this type are unsigned integer numbers in range from 0 to 65535.

type Int < Any;

Integer value. Values of this type are signed integer numbers in range from −2³¹ to 2³¹−1.

type Long < Any;

Long integer value. Values of this type are signed integer numbers in range from −2⁶³ to 2⁶³−1.

type Float < Any;

Single precision floating point number.

type Double < Any;

Double precision floating point number.

type Bool < Any;

Boolean value. Values of this type are true and false.

type String < Any;

A sequence of characters.

type Array < Any;

Parent type or all array types.

type Structure < Any;

Parent type of all structure types.

type Function < Any;

Parent type of all functional types.

type Error < Any;

Error thrown in exceptional situations. See error.eh for details.

Function details

def Any.tostr(): String;

Returns string representation of the value. If value is:

String - value itself is returned;
Int, Long, Float or Double - string representation as a decimal number is returned;
Bool - string "true" or "false" is returned;
StrBuf - new string allocated with characters currently contained in the buffer;
Function - the name of the function is returned;
Array - the string containing all array elements, separated by commas, is returned;
null - function returns string "null".

It is safe to call this function for values of other types but returned values are platform dependant and you should not rely on them.

def String.len(): Int;

Returns length of the string.

def String.ch(at: Int): Char;

Returns character at given position in the string. You may also use square brackets, as with array.

def String.substr(from: Int, to: Int): String;

Returns substring of the string. Returned substring contains all characters in range from..to-1.

def chstr(ch: Char): String;

Returns string containing single character.

def acopy(src: Array, sofs: Int, dest: Array, dofs: Int, len: Int);

Copies len elements from array src starting at index sofs to array dest starting at index dofs.

def Structure.clone(): Structure;

Clones structure. The returned value is new structure of the same type with all fields copied from the old structure.
