ConfigObject (Groovy 2.1.8)

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.

1.5

public Writer writeTo(Writer outArg)
               throws IOException
```
    Writes this config object into a String serialized representation which can later be parsed back using the parse() method
    
    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:
    
    IOException - if an error occurred while outputting data to the writer
    See Also:
    Writable.writeTo(java.io.Writer)
  - getProperty
```
public Object getProperty(String name)
```
    Overrides the default getProperty implementation to create nested ConfigObject instances on demand for non-existent keys
    
    Specified by:
    
    getProperty in interface GroovyObject
    
    Overrides:
    
    getProperty in class GroovyObjectSupport
    
    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
```
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
  - size
```
public int size()
```
    Specified by:
    
    size in interface Map

```
public ConfigObject clone()
```
    Returns a shallow copy of this ConfigObject, keys and configuration entries are not cloned.
