Constructor Detail

DefaultLister

public DefaultLister()

Creates the default Lister.

Method Detail

getPaje

public Paje getPaje()
             throws java.io.IOException

Returns a Paje to display a list of Entity objects.

The default implementation calls createPaje(), then Lister.build(). It then uses PagingLister.getFirstIndex() and PagingLister.getLastIndex() to determine whether the ListerTemplate.getNavigateFirst(org.pajes.html.Container) and ListerTemplate.getNavigatePrevious(org.pajes.html.Container), or ListerTemplate.getNavigateNext(org.pajes.html.Container) and ListerTemplate.getNavigateLast(org.pajes.html.Container) tags should be setWritable(false) or in fact whether the entire ListerTemplate.getNavigationRow(org.pajes.html.Container) should not be written. If it should, and ListerTemplate.getNavigateUptoMessage(org.pajes.html.Container) returns a valid HTML item, then its content will be set to the String returned by getUpToMessage().

Specified by:

getPaje in class Lister

Returns:

The paje.

Throws:

java.io.IOException - if an error occurs creating the lister paje.

createPaje

protected Paje createPaje()
                   throws java.io.IOException

Creates the Paje to display a list of Entity objects.

The Paje to be returned will be determined as follows:

1. If a Lister has been defined, it will be requested to create a document.
2. if noLister has been defined, the ServletContext will be searched for an attribute named LISTER_FACTORY, and the object returned by ServletContext.getAttribute will be requested to create a document. Context default Lister factory objects should be created in your Initialisation sub-class.
3. if no Entity- or context- specific document has been created, a default document will be created.

Once a document has been instantiated, the Container identified by ListerTemplate.LIST_CONTAINER_ID will be retrieved. If this container is empty, the Table returned by getTable() will be added to the container.

Note that the table to be populated must contain two prototype rows for displaying odd and even numbered records. These table rows must have id attributes of oddPrototype and evenPrototype respectivlely. The table may optionally contain a row with an id attribute of addRow, which should contain an anchor or a button to add a new Entity.

Returns:

A new Paje instance.

Throws:

java.io.IOException - if an error occurs creating the lister paje.

EntityException - if an error occurs creatign the paje.

getTable

protected Table getTable()

Returns the Table that can be used to display a list of Entity objects managed by this object. All columns will be displayed, except those where Attributes.getListerPosition() returns a number less than zero.

This implementation creates a new Table, and then populates it by calling the following methods in the sequence shown:

1. getTableHeader(org.pajes.html.Table.Row, java.util.Collection)
2. getTableOddPrototype(org.pajes.html.Table.Row, java.util.Collection)
3. getTableEvenPrototype(org.pajes.html.Table.Row, java.util.Collection)
