Method Detail

getStaticLocationFor

public int getStaticLocationFor(java.lang.String loc)
                         throws BadParameterException

This is used by the StaticMethodEvent to determine which valueChanged method to call. An integer index is returned which is used by the valueChanged (int,ValueChangedEvent) method. This adds the "trigger" method.

Overrides:

getStaticLocationFor in class Manipulator

Throws:

BadParameterException

getUrl

public java.lang.String getUrl()

Returns:

Returns the fileName.

isReadAsBinary

public boolean isReadAsBinary()

Set to true to read data from the URL as binary. Useful for, for example, images.

Returns:

true if the contents of the URL will be read as binary data.

setReadAsBinary

public void setReadAsBinary(boolean readAsBinary)

Set to true to read data from the URL as binary. Useful for, for example, images.

Parameters:

readAsBinary - set to true to read the contents of the URL as binary data.

setUrl

public void setUrl(java.lang.String url)

Set the url to read the data from

trigger

public void trigger(ValueChangedEvent newEvent)
             throws VIBUpdateFailedException

Read the file and send it to the output.

Parameters:

newEvent - an event from the registered data source

Throws:

VIBUpdateFailedException

See Also:

SimpleDataSource.setValueObject(ValueObjectInterface)

valueChanged

public void valueChanged(int loc,
                         ValueChangedEvent e)
                  throws VIBUpdateFailedException,
                         BadParameterException

This calls the proper valueChanged method based on the return from the getStaticLocationFor method.

Overrides:

valueChanged in class Manipulator

Throws:

VIBUpdateFailedException

BadParameterException
