Method Detail

getGUIIndicator

public java.lang.String getGUIIndicator(MMObjectNode node)

Description copied from class: MMObjectBuilder

What should a GUI display for this node. Default is the first non system field (first field after owner). Override this to display your own choice (see Images.java).

Overrides:

getGUIIndicator in class MMObjectBuilder

Following copied from class: org.mmbase.module.core.MMObjectBuilder

Parameters:

node - The node to display

Returns:

the display of the node as a String

getValue

public java.lang.Object getValue(MMObjectNode node,
                                 java.lang.String field)

Description copied from class: MMObjectBuilder

Provides additional functionality when obtaining field values. This method is called whenever a Node of the builder's type fails at evaluating a getValue() request (generally when a fieldname is supplied that doesn't exist). It allows the system to add 'functions' to be included with a field name, such as 'html(body)' or 'time(lastmodified)'. This method will parse the fieldname, determining functions and calling the MMObjectBuilder.executeFunction(org.mmbase.module.core.MMObjectNode, java.lang.String, java.lang.String) method to handle it. Functions in fieldnames can be given in the format 'functionname(fieldname)'. An old format allows 'functionname_fieldname' instead, though this only applies to the text functions 'short', 'html', and 'wap'. Functions can be nested, i.e. 'html(shorted(body))'. Derived builders should override this method only if they want to provide virtual fieldnames. To provide addiitonal functions, override MMObjectBuilder.executeFunction(org.mmbase.module.core.MMObjectNode, java.lang.String, java.lang.String) instead.

Overrides:

getValue in class MMObjectBuilder

Following copied from class: org.mmbase.module.core.MMObjectBuilder

Parameters:

node - the node whos efields are queries

field - the fieldname that is requested

Returns:

the result of the 'function', or null if no valid functions could be determined.

getGUIIndicator

public java.lang.String getGUIIndicator(java.lang.String field,
                                        MMObjectNode node)

Description copied from class: MMObjectBuilder

What should a GUI display for this node/field combo. Default is null (indicating to display the field as is) Override this to display your own choice.

Overrides:

getGUIIndicator in class MMObjectBuilder

Following copied from class: org.mmbase.module.core.MMObjectBuilder

Parameters:

node - The node to display

field - the name field of the field to display

Returns:

the display of the node's field as a String, null if not specified
