wyal.lang.WyalFile.Expr.Operator

All Implemented Interfaces:

Cloneable, Comparable<wybs.lang.SyntacticItem>, WyalFile.Expr, WyalFile.Stmt, wybs.lang.SyntacticElement, wybs.lang.SyntacticItem

Direct Known Subclasses:

Formula.Conjunct, Formula.Disjunct, Formula.Equality, WyalFile.Expr.ArrayAccess, WyalFile.Expr.ArrayGenerator, WyalFile.Expr.ArrayInitialiser, WyalFile.Expr.ArrayLength, WyalFile.Expr.ArrayUpdate, WyalFile.Expr.Dereference, WyalFile.Expr.InfixOperator, WyalFile.Expr.LogicalNot, WyalFile.Expr.Negation

Enclosing interface:

WyalFile.Expr

public abstract static class WyalFile.Expr.Operator
extends wybs.util.AbstractSyntacticItem
implements WyalFile.Expr

Represents an abstract operator expression over one or more operand expressions. For example. in arr[i+1] the expression i+1 is an operator expression.
