Class Configuration

java.lang.Object

de.sciss.syntaxpane.util.Configuration

All Implemented Interfaces:

java.util.Map<java.lang.String,java.lang.String>

public class Configuration
extends java.lang.Object
implements java.util.Map<java.lang.String,java.lang.String>

Wrapper around the Properties class with supprt for Heirarchical confogurations and more functionality. Except for the getXXXX methods, all other Map Interface methods operate on the current (non-parent) collection and do NOT touch the parent.

Constructor Detail

Configuration

public Configuration(java.lang.Class theClass,
                     Configuration parent)

Creates a new COnfiguration that uses parent as its parent Configuration.

Parameters:

theClass -

parent -

Configuration

public Configuration(java.lang.Class theClass)

Creates an empty Configuration

Parameters:

theClass -

Method Detail

getString

public java.lang.String getString(java.lang.String key)

Get a string from this object or one of its parents. If nothing is found, null is returned. If the Regex ${key} is found, then it is replaced by the value of that key within this (or parent's) map. Special Constructs in ${}:

• class_path will be replaced by the name of the Configuration (usually ClassName) with "." replaced by "/", and then converted to all lowercase
• class_simpleName is replaced by class.SimpleName

Parameters:

key -

Returns:

getString

public java.lang.String getString(java.lang.String key,
                                  java.lang.String defaultValue)

Returns a non-null value either by traversing the current and parent(s) map, or returning the defaultValue

Parameters:

key -

defaultValue -

Returns:

Throws:

java.lang.NullPointerException - if defaultValue is null

getInteger

public int getInteger(java.lang.String key,
                      int Default)

Gets an integer from the properties. If number cannot be found or if it cannot be decoded, the default is returned The integer is decoded using Integer.decode(String)

Parameters:

key -

Default -

Returns:

getPropertyList

public java.lang.String[] getPropertyList(java.lang.String key)

Returns a String[] of the comma separated items in the value. Does NOT return null. If the key is not found, then an empty string array is returned. So the return of this method can always be used directly in a foreach loop

Parameters:

key -

Returns:

non-null String[]

getBoolean

public boolean getBoolean(java.lang.String key,
                          boolean Default)

Returns a boolean from the configuration

Parameters:

key -

Default -

Returns:

getColor

public java.awt.Color getColor(java.lang.String key,
                               java.awt.Color Default)

return the Color that has the given key or the Default

Parameters:

key -

Default -

putAll in interface java.util.Map<java.lang.String,java.lang.String>

stringPropertyNames

public java.util.Set<java.lang.String> stringPropertyNames()

Returns ALL property names from this Configuration's parents and this Configuration. As usual, parents are added first so they are overriden by children.

Returns:

Set of all String keys in this and parents

getKeys

public java.util.Set<Configuration.StringKeyMatcher> getKeys(java.util.regex.Pattern pattern)

Obtain a set of all keys (and parent's keys) that match the given pattern. If no keys match, then an empty set is returned. Use this instead of the stringPropertyNames
