Returns the abbreviated name of the type.

指定者:

getName 在接口中 Type

返回:

String the Hibernate type name

getRegistrationKeys

public String[] getRegistrationKeys()

从接口复制的说明: BasicType

Get the names under which this type should be registered in the type registry.

指定者:

getRegistrationKeys 在接口中 BasicType

覆盖:

getRegistrationKeys 在类中 AbstractStandardBasicType<Long>

返回:

The keys under which to register this type.

getDefaultValue

public Serializable getDefaultValue()

从接口复制的说明: PrimitiveType

Get this type's default value.

指定者:

getDefaultValue 在接口中 PrimitiveType<Long>

返回:

The default value.

getPrimitiveClass

public Class getPrimitiveClass()
