Jolt 1.2 Developer's Guide

JoltList
This is a Jolt-aware extension of java.awt.List that is linked to a specific Jolt field in the Jolt input or output buffer by its
JoltFieldName property. If the field occurs multiple times in the Jolt input buffer, the occurrence this list is linked to is
specified by the occurrenceIndex property of this bean. JoltList can be connected with JoltServiceBeans in two ways:
JoltList contains parts of the input for a service. A JoltServiceBean listens to events raised by a JoltList. JoltList
sends JoltInputEvents to its listeners when the selection in the listbox changes. The JoltInputEvent, in this case, is
populated with the single value of the selected item.
●
JoltList displays output from a service. When used to display the output of a service, JoltList listens to
JoltOutputEvents from JoltServiceBeans and updates its contents accordingly with all occurrences of the field to
which it is linked.
●
JoltCheckbox
The JoltCheckbox is a Jolt-aware extension of java.awt.Checkbox that is linked to a specific field in the Jolt input buffer
by its JoltFieldName property. If the field occurs multiple times, the occurrence this checkbox is linked to is specified
by the occurrenceIndex property of this bean.
It can be connected with JoltServiceBeans to contain parts of the input for a service. A JoltServiceBean may listen to
events raised by a JoltCheckbox. JoltCheckbox sends JoltInputEvents to its listeners (typically JoltServiceBeans) when
the selection in the checkbox changes. The JoltInputEvent in this case is populated with the TrueValue property of data
type String (if the box is selected) or FalseValue (if the box is unselected).
JoltChoice
The JoltChoice provides a Jolt-aware extension of java.awt.Choice that is linked to a specific field in the Jolt input
buffer by its JoltFieldName property. If the field occurs multiple times, the occurrence this choice is linked to is
specified by the occurrenceIndex property of this bean.
It can be connected with JoltServiceBeans to contain parts of the input for a service. A JoltServiceBean may listen to
events raised by a JoltChoice. JoltChoice sends JoltInputEvents to its listeners (typically JoltServiceBeans) when the
selection in the choicebox changes. The JoltInputEvent in this case is populated with the single value of the selected
item.
Note
For a detailed description of these classes, see the online Javadoc class reference library.
Using the Property List and the Property Editor to Modify
the JoltBeans Properties
The values of most JoltBeans properties can be modified by simply editing the right column of the Property List shown
in Figure 7-2.
For some properties of JoltBeans, Custom Property Editors are provided.
The Custom Property Editors, accessed from the Property List, include dialog boxes that are used to modify the property
values. You can invoke the Custom Property Editors from the Property List by selecting the button with the ellipsis "..."
that is next to the value of the corresponding property value.
