# Interface SmiTextualConvention

All Superinterfaces:
  `Comparable<SmiObject>, SmiObject, SmiValueType`

public interface SmiTextualConvention extends SmiObject, SmiValueType
The SmiTextualConvention represents the SMIv2 TEXTUAL-CONVENTION and the SMIv1 type assignment construct. Although this interface extends `SmiObject`, it will always return `null` for `SmiObject.getOID()` because textual conventions do not have an OID.
