Nested Classes

Modifier and Type	Interface	Description
static final record	Expr.Assign	Expression that assigns a value to a variable.
static final record	Expr.Binary	Expression for binary operators that operate on two expression (such as "+" to sum numbers).
static final record	Expr.Call	Expression that calls a SolaScriptCallable with desired arguments.
static final record	Expr.CallOptional	Expression that calls a SolaScriptCallable with desired arguments.
static final record	Expr.Get	Expression that gets a property from a SolaScriptMap and returns its.
static final record	Expr.GetOptional	Expression that gets a property from a SolaScriptMap and returns its.
static final record	Expr.Grouping	Grouping expressions warps an expression to change when it is evaluated.
static final record	Expr.Literal	Literal expressions hold a value such as string, number, boolean, map or null.
static final record	Expr.Logical	Expression for logical operators that operate on two expression (such as "||" to evaluate a logical or).
static final record	Expr.NullishCoalescence	Expression for nullish coalescence operator that evaluates to the right side expression if the left side expression evaluates to null.
static final record	Expr.Set	Expression that sets a property on a SolaScriptMap.
static final record	Expr.Ternary	Expression for a ternary operation.
static final record	Expr.Unary	Expression for unary operators that operate on one expression (such as "!" to invert a boolean).
static final record	Expr.Variable	Variable expressions hold a name of a variable to evaluate the value of.
static interface	Expr.Visitor<R>	Defines operations for the various Expr implementations.
