Example 1 with EnumValue

use of com.google.protobuf.EnumValue in project cel-java by projectnessie.

the class FieldDescription method getFrom.

/**
 * GetFrom returns the accessor method associated with the field on the proto generated struct.
 *
 * <p>If the field is not set, the proto default value is returned instead.
 *
 * <p>This function implements the FieldType.GetFrom function contract which can be used to
 * operate on more than just protobuf field accesses; however, the target here must be a
 * protobuf.Message.
