groovy.util.ConfigObject

All Implemented Interfaces and Traits:

Writable, Map, Cloneable
```
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

    Returns a shallow copy of this ConfigObject, keys and configuration entries are not cloned.
    Returns:
    a shallow copy of this ConfigObject

  - @Override
    public Set entrySet()
  - 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
  - public Map flatten(Map target)
    
    Flattens this ConfigObject populating the results into the target Map
    See Also:
    ConfigObject.flatten
  - @Override
    public Object get(Object key)
  - public URL getConfigFile()
  - @Override
    public Object getProperty(String name)
    
    Overrides the default getProperty implementation to create nested ConfigObject instances on demand for non-existent keys
  - @Override
    public boolean isEmpty()
  - 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
    Since:
    2.3.0
  @Override
  public Set keySet()
  
  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
  
  public String prettyPrint()
  
  @Override
  public Object put(Object key, Object value)
  
  @Override
  public void putAll(Map m)
  
  @Override
  public Object remove(Object key)
  
  public void setConfigFile(URL configFile)
  
  @Override
  public int size()
  
  public Properties toProperties()
  
  Converts this ConfigObject into the java.util.Properties format, flattening the tree structure beforehand
  Returns:
  A java.util.Properties instance
  
  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
  
  @Override
  public String toString()
  
  @Override
  public Collection values()
  
  @Override
  public Writer writeTo(Writer outArg)
  
  Writes this config object into a String serialized representation which can later be parsed back using the parse() method
