方法详细资料

getName

public String getName()

从接口复制的说明: Type

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<Double>

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<Double>

返回:

The default value.

getPrimitiveClass

public Class getPrimitiveClass()

从接口复制的说明: PrimitiveType

Retrieve the primitive counterpart to the wrapper type identified by Type.getReturnedClass().

指定者:

getPrimitiveClass 在接口中 PrimitiveType<Double>

返回:

The primitive Java type.

objectToSQLString

public String objectToSQLString(Double value,
                                Dialect dialect)
                         throws Exception

从接口复制的说明: LiteralType

Convert the value into a string representation, suitable for embedding in an SQL statement as a literal.

指定者:

objectToSQLString 在接口中 LiteralType<Double>

参数:

value - The value to convert

dialect - The SQL dialect

返回:

The value's string representation

抛出:

Exception - Indicates an issue converting the value to literal string.
