ConfigObject (Groovy 5.1.0)
Description: declaration: package: groovy.util, class: ConfigObject

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.

Since:
  1.5

    Specified by:
      `writeTo` in interface `Writable`
    Parameters:
      `outArg` - the Writer to which this Writable should output its data.
    Returns:
      the Writer that was passed
    Throws:

    Overrides the default getProperty implementation to create nested ConfigObject instances on demand for non-existent keys
    Specified by:
      `getProperty` in interface `GroovyObject`
    Parameters:
      `name` - the name of the property of interest
    Returns:
      the given property

  - ### 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
    See Also:
      - `flatten()`

  - ### merge

    Parameters:
      `other` - The ConfigObject to merge with
    Returns:
      The result of the merge

  - ### toProperties

    public Properties toProperties()
    Converts this ConfigObject into 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

  - ### size

  - ### isEmpty

    public boolean isEmpty()
    Specified by:
      `isEmpty` in interface `Map`

  - ### containsKey

  - ### 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
