# Enum Class ParameterFormat.ContentLevel

Object
Enum<ParameterFormat.ContentLevel>
ContentLevel

All Implemented Interfaces:
  `Serializable`, `Comparable<ParameterFormat​.ContentLevel>`, `Constable`

Enclosing class:
  `ParameterFormat`

public static enum ParameterFormat.ContentLevel extends Enum<ParameterFormat.ContentLevel>
The amount of information to include in the table formatted by `ParameterFormat`. The content level controls whether the formatter should write all names and aliases (at the cost of multi-line rows), or to pickup one name per parameter for a more compact table.

The enumeration value javadoc provide examples of formatting output.

Since:
  0.4

    public static final ParameterFormat.ContentLevel DETAILED
    The most detailed content, which includes name and aliases. Each parameter may be formatted on many lines if they have aliases.

    #### Example

    The Mercator (variant A) example given in `DefaultParameterDescriptorGroup` javadoc, (augmented with parameter aliases) formatted at this level produces a text like below:

           EPSG: Mercator (variant A) (9804)

  - ### BRIEF

    public static final ParameterFormat.ContentLevel BRIEF
    A medium level of content which formats each parameter on a single line. For each parameter only the name is formatted — aliases and identifiers are omitted.

    #### Example

    The Mercator (variant A) example given in `DefaultParameterDescriptorGroup` javadoc formatted at this level produces a text like below:

           EPSG: Mercator (variant A)
           ┌────────────────────────────────┬────────┬────────────┬───────────────┬───────────────┐
           │ Name (EPSG)                    │ Type   │ Obligation │ Value domain  │ Default value │
           ├────────────────────────────────┼────────┼────────────┼───────────────┼───────────────┤
           │ Latitude of natural origin     │ Double │ Mandatory  │  [-80 … 84]°  │         0.0°  │
           │ Longitude of natural origin    │ Double │ Mandatory  │ [-180 … 180]° │         0.0°  │
           │ Scale factor at natural origin │ Double │ Mandatory  │    (0 … ∞)    │         1.0   │
           │ False easting                  │ Double │ Mandatory  │   (−∞ … ∞) m  │         0.0 m │
           │ False northing                 │ Double │ Mandatory  │   (−∞ … ∞) m  │         0.0 m │
           └────────────────────────────────┴────────┴────────────┴───────────────┴───────────────┘

  - ### NAME_SUMMARY

    public static final ParameterFormat.ContentLevel NAME_SUMMARY
    Limits the content to names and aliases in a tabular format. In addition to parameters, this level can also format array of operation method, coordinate reference system, etc. The summary contains the identifier names and aliases aligned in a table.

    #### Example

    The Mercator (variant A) example given in `ParameterBuilder` javadoc formatted at this level produces a text like below:

           EPSG: Mercator (variant A)
           ┌────────────────────────────────┬────────────────────┐
           │ EPSG                           │ OGC                │
           ├────────────────────────────────┼────────────────────┤
           │ Latitude of natural origin     │ latitude_of_origin │
           │ Longitude of natural origin    │ central_meridian   │
           │ Scale factor at natural origin │ scale_factor       │
           │ False easting                  │ false_easting      │
           │ False northing                 │ false_northing     │
           └────────────────────────────────┴────────────────────┘

    #### Tip

    The table formatted by default may be quite large. It is recommended to invoke `ParameterFormat​.setPreferredCodespaces(String[])` before to format in order to reduce the number of columns to display.

- ## Method Details

  - ### values

    public static ParameterFormat.ContentLevel[] values()
    Returns an array containing the constants of this enum class, in the order they are declared.
    Returns:
      an array containing the constants of this enum class, in the order they are declared

  - ### valueOf

    public static ParameterFormat.ContentLevel valueOf(String name)
    Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

      `name` - the name of the enum constant to be returned.
    Returns:
      the enum constant with the specified name
    Throws:
      `IllegalArgumentException` - if this enum class has no constant with the specified name
      `NullPointerException` - if the argument is null
