getInfo

public java.lang.String getInfo(java.lang.String param1,
                                javax.servlet.ServletRequest param2,

getList

public NodeList getList(java.lang.String param1,
                        java.lang.String param2,
                        java.lang.String param3)

Description copied from interface: NodeManager

Returns a list of nodes belonging to this node manager. Constraints can be given to exclude nodes from the returned list. These constraints follow the syntax of the SQL where clause. It's a good practice to use uppercase letters for the operators and lowercase letters for the fieldnames. Example constraints are:

 "number = 100" (!=, <, >, <= and >= can also be used)
 "name = 'admin'",
 "email IS NULL" (indicating the email field is empty)
 "email LIKE '%.org'" (indication the email should end with .org)
 "number BETWEEN 99 AND 101"
 "name IN ('admin', 'anonymous')"
 

The NOT operator can be used to get the opposite result like:

 "NOT (number = 100)"
 "NOT (name = 'admin')",
 "email IS NOT NULL"
 "email NOT LIKE '%.org'" (indication the email should not end with .org)
 "number NOT BETWEEN 99 AND 101"
 "name NOT IN ('admin', 'anonymous')"
 

Some special functions (not part of standard SQL, but most databases support them) can be used like:

 "LOWER(name) = 'admin'" (to also allow 'Admin' to be selected)
 "LENGTH(name) > 5" (to only select names longer then 5 characters)
 

Constraints can be linked together using AND and OR:

 "((number=100) OR (name='admin') AND email LIKE '%.org')"
 

The single quote can be escaped using it twice for every single occurence:

 "name='aaa''bbb'" (if we want to find the string aaa'bbb)
 

For more info consult a SQL tutorial like this one.

Specified by:

getList in interface NodeManager

Following copied from interface: org.mmbase.bridge.NodeManager

Parameters:

constraints - Contraints to prevent nodes from being included in the resulting list which would normally by included or null if no contraints should be applied .

orderby - A comma separated list of field names on which the returned list should be sorted or null if the order of the returned virtual nodes doesn't matter.

directions - A comma separated list of values indicating wether to sort up (ascending) or down (descending) on the corresponding field in the orderby parameter or null if sorting on all fields should be up. The value DOWN (case insensitive) indicates that sorting on the corresponding field should be down, all other values (including the empty value) indicate that sorting on the corresponding field should be up. If the number of values found in this parameter are less than the number of fields in the orderby parameter, all fields that don't have a corresponding direction value are sorted according to the last specified direction value.

Returns:

a list of nodes belonging to this node manager
