All Implemented Interfaces:
Serializable
Direct Known Subclasses:
ParserConfig, WriterConfig

public class RioConfig extends Object implements Serializable
Superclass for ParserConfig and WriterConfig.

A RioConfig is a container for several RioSetting objects, each of which has a default value. You can override the default value for a RioSetting in one of two ways:

  1. You can programmatically set its value using set(RioSetting, Object)
  2. You can set a Java system property (e.g. by means of a -D jvm command line switch). The property name should corresponds to the key of the setting. Note that this method is not supported by every type of RioSetting: boolean values, strings, and numeric (long) values are supported, but more complex types are not

    • get

      public <T> T get(RioSetting<T> setting)
      Return the value for a given RioSetting or the default value if it has not been set.
      Parameters:
      setting - The RioSetting to fetch a value for.
      Returns:
      The value for the parser setting, or the default value if it is not set.
    • set

      public <T> RioConfig set(RioSetting<T> setting, T value)
      Sets a RioSetting to have a new value. If the value is null, the parser setting is removed and the default will be used instead.
      Parameters:
      setting - The setting to set a new value for.
      value - The value for the parser setting, or null to reset the parser setting to use the default value.
      Returns:
      Either a copy of this config, if it is immutable, or this object, to allow chaining of method calls.
    • isSet

      public <T> boolean isSet(RioSetting<T> setting)
      Checks for whether a RioSetting has been explicitly set by a user.

      A setting can be set via set(RioSetting, Object), or via use of a system property.

      Parameters:
      setting - The setting to check for.
      Returns:
      True if the setting has been explicitly set, or false otherwise.
    • useDefaults

      public RioConfig useDefaults()
      Resets all settings back to their default values.
      Returns:
      Either a copy of this config, if it is immutable, or this object, to allow chaining of method calls.
