Detailed Description
An expression.
There is never an instance of this class
Compiles either:
- an arithmetic expression in parentheses – CBotExpression – (...)
- unary operation – CBotExprUnaire – -a, +a, ~a, !a, not a
- a variable name – CBotExprVar
- pre- or post- incremented or decremented variable – CBotPreIncExpr, CBotPostIncExpr – a++, ++a, a–, –a
- a function call – CBotInstrCall
- a class method call – CBotInstrMethode
- number literal (or numerical constant from CBotToken::DefineNum()) – CBotExprLitNum
- string literal – CBotExprLitString
- boolean literal – CBotExprLitBool – true/false
- null – CBotExprLitNull
- nan – CBotExprLitNan
- class instance creation with "new" – CBotNew
