Constructor Detail

Script_Switch

public Script_Switch(java.lang.String scriptType,
                     java.lang.String elemID)

Create a new instance of Script_Switch.

Parameters:

scriptType - the script element type. This is also the element tag name and should not be null.

elemID - this is the external id used to identify this element specifically. The element is also stored under this value and so it cannot be null.

Script_Switch

public Script_Switch(org.licas_xml.abs.Element autoXml)
              throws java.lang.Exception

Create a new instance of Script_Switch and add the xml-based description of the element values.

Parameters:

autoXml - the xml-based description of values to add.

Throws:

java.lang.Exception - any error.

Method Detail

addCase

protected Script_Case addCase(java.lang.String source,
                              java.lang.String operation,
                              Script_Variable vars,
                              java.lang.String filter,
                              Script_Event effector)
                       throws java.lang.Exception

Create and add a new case statement to this switch statement. Automatically set the case ID. The other values can be passed in as parameters or set later in the returned case statement. So any parameter can be null here and set later.

Parameters:

source - reference to the source to execute the operation on.

operation - name of the method or operation to execute for the case.

vars - variable(s) that the operation might use.

filter - filter reference to filter any operation reply with.

effector - return this effector event if the case statement is correct.

Returns:

the case statement that is created.

Throws:

java.lang.Exception - any error.
