Package groovy.util

Class ConfigObject

java.lang.Object
groovy.lang.GroovyObjectSupport
groovy.util.ConfigObject
All Implemented Interfaces:
GroovyObject, Writable, Cloneable, Map
public class ConfigObject extends GroovyObjectSupport implements Writable, Map, Cloneable
A ConfigObject at a simple level is a Map that creates configuration entries (other ConfigObjects) when referencing them. This means that navigating to foo.bar.stuff will not return null but nested ConfigObjects which are of course empty maps The Groovy truth can be used to check for the existence of "real" entries.

    • flatten

      public Map flatten()
      A ConfigObject is a tree structure consisting of nested maps. This flattens the maps into a single level structure like a properties file

    • flatten

      public Map flatten(Map target)
      Flattens this ConfigObject populating the results into the target Map

    • merge

      public Map merge(ConfigObject other)
      Merges the given map with this ConfigObject overriding any matching configuration entries in this ConfigObject
      Parameters:
      other - The ConfigObject to merge with
      Returns:
      The result of the merge

    • toProperties

      public Properties toProperties()
      Converts this ConfigObject into a the java.util.Properties format, flattening the tree structure beforehand
      Returns:
      A java.util.Properties instance

    • toProperties

      public Properties toProperties(String prefix)
      Converts this ConfigObject ino the java.util.Properties format, flatten the tree and prefixing all entries with the given prefix
      Parameters:
      prefix - The prefix to append before property entries
      Returns:
      A java.util.Properties instance

    • clone

      public ConfigObject clone()
      Returns a shallow copy of this ConfigObject, keys and configuration entries are not cloned.
      Overrides:
      clone in class Object
      Returns:
      a shallow copy of this ConfigObject

    • isSet

      public Boolean isSet(String option)
      Checks if a config option is set. Example usage: 
       def config = new ConfigSlurper().parse("foo { password='' }")
 assert config.foo.isSet('password')
 assert config.foo.isSet('username') == false
      The check works only for options one block below the current block. E.g. config.isSet('foo.password') will always return false.
      Parameters:
      option - The name of the option
      Returns:
      true if the option is set false otherwise
