    • isInstance

      public boolean isInstance(Object value)
      Description copied from interface: JavaType
      Is the given value an instance of the described type?

      Usually just getJavaTypeClass().isInstance(value), but some descriptors need specialized semantics, for example, the descriptors for java.sql.Date, java.sql.Time, and java.sql.Timestamp.

      For EntityJavaType, this method handles proxies in a semantically correct way, by checking the entity instance underlying the proxy object.

      Specified by:
      isInstance in interface JavaType<Date>

    • cast

      public Date cast(Object value)
      Description copied from interface: JavaType
      Apply a simple type cast to the given value, without attempting any sort of coercion or wrapping. This method is provided as a convenient way to avoid an unchecked cast to a type variable. Use javaType.cast(value) instead of (T) value wherever possible.

      Usually just getJavaTypeClass().cast(value), but overridden in some cases as an "optimization". This optimization is almost certainly unnecessary, and might even indeed be harmful, since Class.cast() is an intrinsic.

      Specified by:
      cast in interface JavaType<Date>

    • fromString

      public Date fromString(CharSequence string)

    • areEqual

      public boolean areEqual(Date one, Date another)
      Description copied from interface: JavaType
      Determine if two instances are equal
      Specified by:

    • extractHashCode

      public int extractHashCode(Date value)
      Description copied from interface: JavaType
      Extract a proper hash code for the given value.
      Specified by:
      extractHashCode in interface JavaType<Date>
      Overrides:
      extractHashCode in class AbstractClassJavaType<Date>
      Parameters:
      value - The value for which to extract a hash code.
      Returns:
      The extracted hash code.

    • unwrap

      public <X> X unwrap(Date value, Class<X> type, WrapperOptions options)
      Description copied from interface: JavaType
      Unwrap an instance of our handled Java type into the requested type.

      As an example, if this is a JavaType<Integer> and we are asked to unwrap the Integer value as a Long, we would return something like Long.valueOf( value.longValue() ).

      Intended use is during PreparedStatement binding.

      Specified by:
      unwrap in interface JavaType<Date>
      Type Parameters:
      X - The conversion type.
      Parameters:
      value - The value to unwrap
      type - The type as which to unwrap
      options - The options
      Returns:
      The unwrapped value.

    • wrap

      public <X> Date wrap(X value, WrapperOptions options)
      Description copied from interface: JavaType
      Wrap a value as our handled Java type.

      Intended use is during ResultSet extraction.

      Specified by:
      wrap in interface JavaType<Date>
      Type Parameters:
      X - The conversion type.
      Parameters:
      value - The value to wrap.
      options - The options
      Returns:
      The wrapped value.

    • coerce

      public Object coerce(Object value)
      Description copied from interface: JavaType
      Coerce the given value to this type, if possible.

      This method differs from wrap() in that it allows simple, basic, implicit type conversions, and does not require WrapperOptions. The wrap() method may be thought of as offering explicitly requested type conversions driven by a choice of JdbcType.

      An implementation of this method reports failure in one of two ways, by:

      Therefore, this method is declared to return Object. In case immediate coercion is required, the following idiom may be used: 

      javaType.cast(javaType.coerce(value))
      Specified by:
      coerce in interface JavaType<Date>
      Parameters:
      value - The value to coerce
      Returns:
      The coerced value, or the given value if no coercion was possible

    • isWider

      public boolean isWider(JavaType<?> javaType)
      Description copied from interface: JavaType
      Determines if this Java type is wider than the given Java type, that is, if the given type can be safely widened to this type.
      Specified by:
      isWider in interface JavaType<Date>

    • next

      public Date next(Date current, Long length, Integer precision, Integer scale, SharedSessionContractImplementor session)

    • seed

      public Date seed(Long length, Integer precision, Integer scale, SharedSessionContractImplementor session)
      Description copied from interface: VersionJavaType
      Generate an initial version.

      Note that this operation is only used when the program sets a null or negative number as the value of the entity version field. It is not called when the program sets the version field to a sensible-looking version.
