public final class Expr
extends com.google.protobuf.GeneratedMessageLite<Expr,Expr.Builder>
implements ExprOrBuilder

 An abstract representation of a common expression.

 Expressions are abstractly represented as a collection of identifiers,
 select statements, function calls, literals, and comprehensions. All
 operators with the exception of the '.' operator are modelled as function
 calls. This makes it easy to represent new operators into the existing AST.

 All references within expressions must resolve to a
 [Decl][google.api.expr.v1alpha1.Decl] provided at type-check for an
 expression to be valid. A reference may either be a bare identifier `name` or
 a qualified identifier `google.api.name`. References may either refer to a
 value or a function declaration.

 For example, the expression `google.api.name.startsWith('expr')` references
 the declaration `google.api.name` within a
 [Expr.Select][google.api.expr.v1alpha1.Expr.Select] expression, and the
 function declaration `startsWith`.
