public sealed class MappingRuleFilter : IMessage<MappingRuleFilter>, IEquatable<MappingRuleFilter>, IDeepCloneable<MappingRuleFilter>, IBufferMessage, IMessage
Reference documentation and code samples for the Database Migration v1 API class MappingRuleFilter.
A filter defining the entities that a mapping rule should be applied to.
When more than one field is specified, the rule is applied only to
entities which match all the fields.
Optional. The rule should be applied to entities whose parent entity
(fully qualified name) matches the given value.
For example, if the rule applies to a table entity, the expected value
should be a schema (schema). If the rule applies to a column or index
entity, the expected value can be either a schema (schema) or a table
(schema.table)
