Method Detail

getKeyDelimiter

public String getKeyDelimiter()

Get the delimiting key (default is '/').

Returns:

setKeyDelimiter

public void setKeyDelimiter(String _keyDelimiter)

Set the delimiting key.
If null is given, default ('/') will be used.

Parameters:

_keyDelimiter -

keyCount

public int keyCount()

Get the amount of nodes in config.

Returns:

getString

public String getString(String _key)

Get the String value behind the given key. Shortcut of getString(String, null).

Parameters:

_key - key to look for

Returns:

value stored in config or null if value not found

getString

public String getString(String _key,
                        String _default)

Get the string value behind the given key or return default.
Will first try to pick up key from environment variables (if enabled),
if that fails, config will be used.
If this also fails, default is returned.

Parameters:

_key - key to look for

_default - default to return if key not found

Returns:

value stored in environment/config or default if key not found

getInt

public int getInt(String _key,
                  int _default)

Get a configuration value as int. If _key not found, or not an integer, default is returned.

Parameters:

_key -

_default -

Returns:

getDouble

public double getDouble(String _key,
                        double _default)

Retrieve a configuration value as double. If _key could not be found, or value was not of type 'double', default is returned.

Parameters:

_key -

_default -

Returns:

getBoolean

public boolean getBoolean(String _key,
                          boolean _default)

Retrieve a configuration value as boolean. If _key could not be found, default is returned.
All other values will be tried to read as boolean.

Considered true values are:

• 1
• y
• j
• ja
• yes
• true
• enabled
• enable
• active

Returns:

setString

public void setString(String _key,
                      boolean _asAttribute,
                      String _value)

Set string value of given key

Parameters:

_key - key to write

_asAttribute - set this as attribute instead of node

_value - value to write

getStringList

public List<String> getStringList(String _key)

Returns the results of key as ArrayList.

Parameters:

_key -

Returns:

never null, maybe empty list

getStringSet

public Set<String> getStringSet(String _key,
                                Class<? extends Set> _setClass)

Returns a result as Set of the given Set-Subclass. If given Set-Class is null or could not be instantiated, TreeSet is used.

Parameters:

_key -

Returns:

setValues

public void setValues(Map<String,String> _values,
                      boolean _asAttributes)

Set keys found in map to value found in map.

Parameters:

_values - values to write
