SchemaFeature

All Known Implementing Classes:

DBTranslatorRecord.AddTextTypeSchemaFeature, DDLSchemaFeature, EncodedStringField.ConvertStringToEncodedSchemaFeature
```
public interface SchemaFeature
```
SchemaFeature is used to ensure that the internal database has particular attributes ("features"). Modules should register schema features on startup through the SchemaUpdater- if a particular feature does not exist (no such FeatureKey present), the apply(DBInterface) function will be called, allowing the implementor to take whatever action it wants.

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`void`	`apply(DBInterface db)`	If the given schema feature is not present in the database, this will be called
`default InternalDBFlavor`	`dbFlavor()`	If a schema feature is only pertinent to a particular internal db flavor, it can return it here.
`java.lang.String`	`getFeatureKey()`	A module-specific key for the named feature

  - getFeatureKey
```
java.lang.String getFeatureKey()
```
    A module-specific key for the named feature
  - apply
```
void apply(DBInterface db)
    throws java.sql.SQLException
```
    If the given schema feature is not present in the database, this will be called
    
    Throws:
    
    java.sql.SQLException
  - dbFlavor
```
default InternalDBFlavor dbFlavor()
```
    If a schema feature is only pertinent to a particular internal db flavor, it can return it here. Otherwise, "Not_Defined" is retuned by default and will apply to all internal databases.
