- All Implemented Interfaces:
Serializable
,Comparable<About>
public enum About extends Enum<About>
Provides information about the Apache SIS running environment. This class collects information from various places likeVersion.SIS
,System.getProperties()
,Locale.getDefault()
orTimeZone.getDefault()
. This class does not collect every possible information. Instead, it tries to focus on the most important information for SIS, as determined by experience in troubleshooting. Some of those information are:- Version numbers (SIS, Java, Operation system).
- Default locale, timezone and character encoding.
- Current directory, user home and Java home.
- Libraries on the classpath and extension directories.
- Since:
- 0.3
Defined in the

values
public static About[] values()
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:for (About c : About.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static About valueOf(String name)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)- Parameters:
name
- the name of the enum constant to be returned.- Returns:
- the enum constant with the specified name
- Throws:
IllegalArgumentException
- if this enum type has no constant with the specified nameNullPointerException
- if the argument is null
-
configuration
public static TreeTable configuration()
Returns all known information about the current Apache SIS running environment. The information are formatted using the system default locale and timezone.This convenience method is equivalent to the following code:
return configuration(EnumSet.allOf(About.class), null, null);
- Returns:
- configuration information, as a tree for grouping some configuration by sections.
-
configuration
public static TreeTable configuration(Set<About> sections, Locale locale, TimeZone timezone)
Returns a subset of the information about the current Apache SIS running environment.- Parameters:
sections
- the section for which information are desired.locale
- the locale to use for formatting the texts in the tree, ornull
for the default.timezone
- the timezone to use for formatting the dates, ornull
for the default.- Returns:
- configuration information, as a tree for grouping some configuration by sections.
