Constructor Detail

Properties

public Properties()

get all the settings from the system properties

Properties

public Properties(Map identifiers)

get all the settings from the system properties then override with provided identifiers

Method Detail

getIdentifier

public String getIdentifier(String key)

setIdentifier

public void setIdentifier(String key,
                          String value)

getIdentifiers

public Map getIdentifiers()

setIdentifiers

public void setIdentifiers(Map<String,String> identifiers)

getCoreKeys

public List getCoreKeys()

Return a list with all keys without the conditions

coreKeys

public Enumeration coreKeys()

getCoreKeys with an enumarator to mimick keys()

Returns:

getProperty

public String getProperty(String name)

Get a property value If there are multiple conditional properties for the same key, fetch the one with the highest condition match.

Overrides:

getProperty in class Properties

getCollection

public Properties getCollection(String prefix)

Fetch all properties that have a certain prefix. If there are multiple conditional properties for the same key, fetch the one with the highest condition match.

Parameters:

prefix -

Returns:

getGroupedCollection

public Map getGroupedCollection(String prefix)

Get all properties that match a prefix and group them. For example: my.collection.1.f.1=A1 my.collection.1.f.2=B1 my.collection.1.f.3=C1 my.collection.3.f.1=A3 my.collection.3.f.2=B3 my.collection.3.f.3=C3 Calling this method with prefix my.collection, returns a map with under the key "1" and "3" two maps containing "f.1" with their respective values. So the result is: [1=>[f.1=>A1, f.3=>C1, f.2=>B1], 3=>[f.1=>A3, f.3=>C3, f.2=>B3]] Often de index is not relevant, but having it in a map makes it a bit of a hassle to navigate (pre 1.5) Using " list.addAll(map.values()); " makes it easier.

Parameters:

prefix -

Returns:
