Package javax.jdo.query Description

Package providing expressions for building a typed JDOQL query. Fields/Params/Vars of a persistable type are represented as Expression. All generated "Q" classes extend "PersistableExpression", and provide the fields/properties of the persistable class as Expression types. Fields/Params/Vars of a container type are represented as CollectionExpression, MapExpression. Fields/Params/Vars of other types, or literals are represented by

• StringExpression
• EnumExpression
• NumericExpression
• BooleanExpression
• ByteExpression
• CharacterExpression
• DateExpression
• DateTimeExpression
• TimeExpression
• ObjectExpression
