    All Methods Instance Methods Abstract Methods Default Methods
    Modifier and Type | Method and Description
    --- | ---
    `String` | `getStringType()` Returns the corresponding Java type of this datatype
    `Object` | `readValue(String value)`
    `default Object` | `valueOf(String value)` Tries to convert string parameter to an object of this type
    `boolean` | `verifyDataType(Object value)` Returns true if the given value is a valid value of this data type.

- - ### Method Detail

    - #### verifyDataType

          boolean verifyDataType(Object value)

      Returns true if the given value is a valid value of this data type.

    - #### writeValue

          String writeValue(Object value)

    - #### readValue

          Object readValue(String value)

    - #### getStringType

          String getStringType()

      Returns the corresponding Java type of this datatype

    - #### valueOf

          default Object valueOf(String value)

      Tries to convert string parameter to an object of this type
      Parameters:
        `value` - to be converted. For the sake of performance, it is assumed to not be null and not of `this` data type.
      Returns:
        object converted to this type, if not possible to convert, the same object passed as parameter
