Constructor Detail

### JdbcDateTypeDescriptor

    public JdbcDateTypeDescriptor()

Method Detail

### toString

    public String toString(Date value)

### fromString

    public Date fromString(String string)

### areEqual

    public boolean areEqual(Date one,
                            Date another)

  Description copied from class: `AbstractTypeDescriptor`
  Determine if two instances are equal

  Specified by:
    `areEqual` in interface `JavaTypeDescriptor<Date>`
  Overrides:
    `areEqual` in class `AbstractTypeDescriptor<Date>`
  Parameters:
    `one` - One instance
    `another` - The other instance
  Returns:
    True if the two are considered equal; false otherwise.

### extractHashCode

    public int extractHashCode(Date value)

  Description copied from class: `AbstractTypeDescriptor`
  Extract a proper hash code for this value.

  Specified by:
    `extractHashCode` in interface `JavaTypeDescriptor<Date>`
  Overrides:
    `extractHashCode` in class `AbstractTypeDescriptor<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: `JavaTypeDescriptor`
  Unwrap an instance of our handled Java type into the requested type.

  As an example, if this is a `JavaTypeDescriptor<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.

  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: `JavaTypeDescriptor`
  Wrap a value as our handled Java type.

  Intended use is during `ResultSet` extraction.

  Type Parameters:
    `X` - The conversion type.
  Parameters:
    `value` - The value to wrap.
    `options` - The options
  Returns:
    The wrapped value.
