Loop

data class Loop(var condition: Expression, var statement: Block, var evaluation: Loop.Evaluation, var line: Int) : AstObject, IsParent

Used to define loops

Example:

int a = 10;
while(a >= 0){
a--;
}

Constructors

constructor(condition: Expression, statement: Block, evaluation: Loop.Evaluation, line: Int)

Types

enum Evaluation : Enum<Loop.Evaluation>

Properties

var condition: Expression

represents an expression evaluated at each iteration

var evaluation: Loop.Evaluation

represents an enum that specifies if the condition is evaluated before or after the statement

open override var line: Int

is the line at which the statement/code component begins in the program text file

open override var parent: IsParent?

is the parent of the node in the Syntax Tree

open override val scope: SymbolTable?

is the scope to which the node belongs

var statement: Block

represents the set of instructions contained inside the loop

Functions

open override fun replaceChild(initial: AstObject, replacement: AstObject)

Is replacing a certain child of the class with another object of the same type If the two parameters don't have the same type, no block will be replaced. If the type of initial doesn't match any of the current node children, no child will be replaced

setParentForChildren

open override fun setParentForChildren()

Sets the object as a parent for its children
