Method Details

create

static <ENTITY> StringField<ENTITY> create(Class<ENTITY> table,
 String columnName,
 ReferenceGetter<ENTITY,String> getter,
 boolean unique)

Creates a new StringField using the default implementation.

Type Parameters:

ENTITY - the entity type

Parameters:

table - the table that the field belongs to

columnName - the name of the database column the field represents

getter - method reference to the getter in the entity

unique - represented column only contains unique values

Returns:

the created field

isNull
