Class Expr

  • All Implemented Interfaces:
    com.google.protobuf.Message, com.google.protobuf.MessageLite, com.google.protobuf.MessageLiteOrBuilder, com.google.protobuf.MessageOrBuilder, ExprOrBuilder, Serializable

    public final class Expr
    extends com.google.protobuf.GeneratedMessageV3
    implements ExprOrBuilder
     Represents a textual expression in the Common Expression Language (CEL)
     syntax. CEL is a C-like expression language. The syntax and semantics of CEL
     are documented at https://github.com/google/cel-spec.
     Example (Comparison):
         title: "Summary size limit"
         description: "Determines if a summary is less than 100 chars"
         expression: "document.summary.size() < 100"
     Example (Equality):
         title: "Requestor is owner"
         description: "Determines if requestor is the document owner"
         expression: "document.owner == request.auth.claims.email"
     Example (Logic):
         title: "Public documents"
         description: "Determine whether the document should be publicly visible"
         expression: "document.type != 'private' && document.type != 'internal'"
     Example (Data Manipulation):
         title: "Notification string"
         description: "Create a notification string with a timestamp."
         expression: "'New message received at ' + string(document.create_time)"
     The exact variables and functions that may be referenced within an expression
     are determined by the service that evaluates it. See the service
     documentation for additional information.
