Method Detail

getCollectorNames

public java.util.List<java.lang.String> getCollectorNames()

Description copied from interface: I_CmsResourceCollector

Returns a list of all collector names (Strings) this collector implementation supports.

Returns:

a list of all collector names this collector implementation supports

See Also:

I_CmsResourceCollector.getCollectorNames()

getCreateLink

public java.lang.String getCreateLink(CmsObject cms,
                                      java.lang.String collectorName,
                                      java.lang.String param)

Description copied from interface: I_CmsResourceCollector

Returns the link that must be executed when a user clicks on the direct edit "new" button on a list created by the named collector.

If this method returns null, it indicated that the selected collector implementation does not support a "create link", and so no "new" button will should shown on lists generated with this collector.

Parameters:

cms - the current CmsObject

collectorName - the name of the collector to use

param - an optional collector parameter

Returns:

the link to execute after a "new" button was clicked

I_CmsResourceCollector.getCreateLink(org.opencms.file.CmsObject, java.lang.String, java.lang.String)

getCreateParam

public java.lang.String getCreateParam(CmsObject cms,
                                       java.lang.String collectorName,
                                       java.lang.String param)

Description copied from interface: I_CmsResourceCollector

Returns the parameter that must be passed to the I_CmsResourceCollector.getCreateLink(CmsObject, String, String) method.

If this method returns null, it indicates that the selected collector implementation does not support a "create link", and so no "new" button will should shown on lists generated with this collector.

Parameters:

cms - the current CmsObject

collectorName - the name of the collector to use

param - an optional collector parameter from the current page context

Returns:

the parameter that will be passed to the I_CmsResourceCollector.getCreateLink(CmsObject, String, String) method, or null
