Details

AbortedConfiguration

Called if the configuration has been aborted due to a casting or parsing error, for example trying to set an int field with a unparseble string value.
Example:

@AbortedConfiguration public void callIfAborted(){
	System.out.println("Configuration has been aborted");
}



AfterConfiguration

Called after each successful configuration.
Example:

@AfterConfiguration public void callAfterEachConfiguration(){
	System.out.println(this+" has been configured");
}



AfterInitialConfiguration

Called after first successful configuration.
Example:

@AfterInitialConfiguration public void callAfterInitialConfigurationOnly(){
	System.out.println(this+" has been INITIALY-configured");
}



AfterReConfiguration

Called after each successful re-configuration.
Example:

@AfterReConfiguration public void callAfterReConfigurationOnly(){
	System.out.println(this+" has been RE-configured");
}



BeforeConfiguration

Called before each configuration attempt.
Example:

@BeforeConfiguration public void callBeforeEachConfiguration(){
	System.out.println(this+" will be configured now");
}



BeforeInitialConfiguration

Called before first configuration attempt.
Example:

@BeforeInitialConfiguration public void callBeforeInitialConfigurationOnly(){
	System.out.println(this+" will be INITIALY configured now");
}



BeforeReConfiguration

Called before each configuration attempt except first.
Example:

@BeforeReConfiguration public void callBeforeReConfigurationOnly(){
	System.out.println(this+" will be RE-configured now");
}



Configure

Marks a field configureable. The field must be either public or have a setter (recommended).
Example:

	@Configure private String greeting;

	public void setGreeting(String greeting) {
		this.greeting = greeting;
	}
	@Configure public String greeting;



ConfigureMe

Marks a class as configurable.

Parameter

default

Description

name

 

Configuration name. If skipped the class name (without package) is used.

watch

true

If true the configuration for the artefact will be watched and the artefact reconfigured as soon as the config changes. It implicitely means that the instance to the artefact will be stored in the configuration management. Don't use on objects which are supposed to die soon after usage (at the end of a request or similar cause it could lead to memory leaks.

type

Type.File

Type of configuration source. Currently supported are File and Fixture.

allfields

false

If true all fields are set from configuration regardless whether they are annotated Configure or not.

 

 

Only fields which are marked DontConfigure are ignored.

Example:

@ConfigureMe(name="fixture", type=ConfigurationSourceKey.Type.FIXTURE, watch=false)
public class TestConfigurable {
@ConfigureMe(allfields=true)
public class HelloWorld {



DontConfigure

Marks a field not configureable. In case the class is annotated with ConfigureMe(allfields=true) this field will be ignored.
Example:

	@DontConfigure private String myField;



Set

Calls the method with the value of the configuration property specified by the value (noname) attribute.

Parameter

default

Description

value

 

Name of the attribute in the configuration object


Example:

@ConfigureMe(name="helloworld", watch=false)
public class LanguageResearcher {
	@Set("greeting")
	public void research(String greeting){
		System.out.println("\tI found out that here people are greeting with \""+greeting+"\"");
	}
}



SetAll

Calls the method with each name, value pair in the configuration object. Requires the target method to have two string parameters.
Example:

@SetAll
public void debug(String name, String value){
	System.out.println(""+name+" is configured as "+value);
}



SetIf

Calls the method with the name and the value of the configuration properties which match value and condition annotation parameters. Value is a string parameter, while condition is one of the SetIfCondition enum values. There are currently 3 of them :

  • startsWith (does the key start with given annotation value)
  • contains (does the key contain given annotation value)
  • matches (does the key match given annotation value)
    All of conditions are checked by calling the String methods of the same name on attribute name (so, the last condition supports regular expressions).

    Parameter

    default

    Description

    value

     

    Pattern of the attribute name in the configuration object

    condition

    SetIfCondition.matches

    Condition, which regulates the configuration properties to be passed to the annotated method


    Example:
    @ConfigureMe(name="serverRegistry", watch=false)
    public class ServerRegistry {
    	@SetIf(value="server", condition=SetIfCondition.startsWith)
    	public void addServer(String serverName, String serverUrl){
    		System.out.println("\tAdded server to registry - \""+serverName +" : "+serverUrl+"\"");
    	}
    }
    
    While processing SetIf annotation in the previous peace of code, the method will be called with all of the configuration properties, which have names starting with "server".
