Class TypeAdapter<D,S>

java.lang.Object

ollie.TypeAdapter<D,S>

Type Parameters:

D - Deserialized type, i.e. the Java type.

S - Serialized type, i.e. the SQLite type.

Direct Known Subclasses:

BooleanAdapter, CalendarAdapter, SqlDateAdapter, UtilDateAdapter

public abstract class TypeAdapter<D,S>
extends java.lang.Object

Type adapters provide a method for which to convert between Java types and SQLite types.

SQLite can only store primitive values in columns. Complex Java data types must, therefore, be converted to a primitive SQLite type. The SQLite types are:

• NULL
• INTEGER
• REAL
• TEXT
• BLOB
