Method Detail

deg2bog

public double deg2bog(double width,
                      double angle)

diffX

public int diffX(double width,
                 int angle)

diffY

public int diffY(double width,
                 int angle)

repaint

public void repaint()

enforceValidValues

public JSONObject enforceValidValues()

step

public JSONObject step(JSONObject jSONObject)
                throws KiemExecutionException
Description copied from interface: IJSONObjectDataComponent
Step method for a DataObserver and a DataPrroducer.

For a producer only the argument will always be null. For an observer only this method will be called asynchronous. This may mean that in case the observer is slow, it may be skipped at some consecutive steps until it becomes ready again. If this is not desired and the observer MUST NOT be skipped, then the DataComponent should also be a DataProducer but return just null.

If an error occurs during the execution of the step method, a DataComponent should raise a KiemExecutionException that is then catched by the execution manager an brought to the user's attention.

Specified by:
step in interface IJSONObjectDataComponent
Parameters:
jSONObject - the concrete JSONObject of input data (if observer)
Returns:
the JSONObject with the output data (if producer)
Throws:
KiemExecutionException - a KiemExecutionException

initialize

public void initialize()
                throws KiemInitializationException
Description copied from interface: IDataComponent
Initialize. Do some initializing prior to execution. If an error occurs during initialization, the DataComponent should raise a KiemInitializationException.

Specified by:
initialize in interface IDataComponent
Throws:
KiemInitializationException - a KiemInitializationException

isObserver

public boolean isObserver()
Description copied from interface: IDataComponent
To check whether the DataComponent is an observer. If the DataComponent is an observer the arguments in its step() method will be != null.

Specified by:
isObserver in interface IDataComponent
Returns:
true, if is observer

isProducer

public boolean isProducer()
Description copied from interface: IDataComponent
To check whether the DataComponent is a producer. If the DataComponent is a producer it should return != null in its step() method.

Specified by:
isProducer in interface IDataComponent
Returns:
true, if is producer

provideInitialVariables

public JSONObject provideInitialVariables()
Description copied from class: JSONObjectDataComponent
Provide (local) interface variables and possible initial values. This is an optional method that will provide some interface variable keys and values that can be used by other DataComponents within and after the initialization phase every DataComponent may receive the union of all those variable keys by calling the JSONObjectDataComponent.getInitialVariables() method.

Overrides:
provideInitialVariables in class JSONObjectDataComponent
Returns:
the local initial variables as a JSONObject

provideProperties

public KiemProperty[] provideProperties()
Description copied from class: AbstractDataComponent
Provide properties for this component. The component may create and publicize its properties with this method. They will be set/modified by the execution manager during the user edits them. Whenever the user decides to run/start the execution the properties are tested (see below) and the component may use there settings.

The following lists a simple example for such properties:
\ATOverride
public KiemProperty[] provideProperties() {
KiemProperty[] properties = new KiemProperty[7];
properties[0] = new KiemProperty(
"state name",
"state");
properties[1] = new KiemProperty(
"some bool",
true);
properties[2] = new KiemProperty(
"an integer",
2);
properties[3] = new KiemProperty(
"a file",
new KiemPropertyTypeFile(),
"c:/nothing.txt");
String[] items = {"trace 1","trace 2", "trace 3", "trace 4"};
properties[4] = new KiemProperty(
"a choice",
new KiemPropertyTypeChoice(items),
items[2]);
properties[5] = new KiemProperty(
"workspace file",
new KiemPropertyTypeWorkspaceFile(),
"/nothing.txt");
properties[6] = new KiemProperty(
"editor",
new KiemPropertyTypeEditor(),
"");
return properties;
}

These are built-in types that can always be extended using the KiemProperty class.

Overrides:
provideProperties in class AbstractDataComponent
Returns:
the KiemProperty[] or null if no properties are provided

wrapup

public void wrapup()
            throws KiemInitializationException
Description copied from interface: IDataComponent
Wrap-up. Do some wrapping-up after execution has finished. If an error occurs during wrap up, the DataComponent should raise a KiemInitializationException.

Specified by:
wrapup in interface IDataComponent
Throws:
KiemInitializationException - a KiemInitializationException
