Descriptor for the SQL/JDBC side of a value mapping.

NOTE : Implementations should be registered with the SqlTypeDescriptor. The built-in Hibernate implementations register themselves on construction.

getBinder

<X> ValueBinder<X> getBinder(JavaTypeDescriptor<X> javaTypeDescriptor)

Get the binder (setting JDBC in-going parameter values) capable of handling values of the type described by the passed descriptor.

参数:

javaTypeDescriptor - The descriptor describing the types of Java values to be bound

返回:

The appropriate binder.

getExtractor

<X> ValueExtractor<X> getExtractor(JavaTypeDescriptor<X> javaTypeDescriptor)

参数:

javaTypeDescriptor - The descriptor describing the types of Java values to be extracted

返回:

The appropriate extractor
