[Java] Class ConfigObject

  • 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

Method Detail

public void clear()

public ConfigObject clone()

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

Returns:
a shallow copy of this ConfigObject

public boolean containsKey(Object key)

public boolean containsValue(Object value)

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

public Object get(Object key)

public URL getConfigFile()

public Object getProperty(String name)

Overrides the default getProperty implementation to create nested ConfigObject instances on demand for non-existent keys

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

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()

public Object put(Object key, Object value)

public void putAll(Map m)

public Object remove(Object key)

public void setConfigFile(URL configFile)

public int size()

public Properties toProperties()

Converts this ConfigObject into a 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()

public Collection values()

public Writer writeTo(Writer outArg)

Writes this config object into a String serialized representation which can later be parsed back using the parse() method
