config

public <T> T config(Class<?> front,
 String prefix)

This method returns an interface that can be used to get and set the properties in a type safe way (as well as describing any semantics of these properties).

The interface must have get and/or set methods. The name is mangled to change _ to . and to remove $ (which is used to mask keywords like new). If _ and $ are in there twice, one remains. The set methods return the proxy object itself so you can use it in a builder style.

The values are always stored as strings (and can use macros). The result is converted to the desired type. Arguments in the set methods are always converted to strings using the toString methods.

Example:

  interface MyConfig { int level(); MyConfig level(int level);
 Pattern pattern(); MyConfig pattern(String p); } Env env = ... MyConfig c
 = env.config(MyConfig.class, "myconfig.");
 

Parameters:

front - the fronting interface

prefix - the prefix in the properties

Returns:

an interface that can be used to get and set properties

config

public <T> T config(Class<?> front)

mangleMethodName

String mangleMethodName(String prefix,
 String string)

isTrue

public boolean isTrue(String v)
