getMapAttr

public static String getMapAttr(Map map,
                                String name,
                                String defaultValue)

getMapAttrThrows

public static String getMapAttrThrows(Map map,
                                      String key)
                               throws ValueNotFoundException

Return String from a map of strings to set of strings.

Parameters:

map - Map of string of set of string.

name - Key of the map entry.

Returns:

the String value from a map of strings to set of strings.

Throws:

ValueNotFoundException - if no value is found for the key.

getMapSetThrows

public static Set<String> getMapSetThrows(Map<String,Set<String>> map,
                                          String key)
                                   throws ValueNotFoundException

Gets the set based on the passed key.

Parameters:

map - the map

key - key to lookup

Returns:

associated set

Throws:

ValueNotFoundException - should the key not exist

getLocaleMapAttrThrows

public static Map<Locale,String> getLocaleMapAttrThrows(Map<String,Set<String>> map,
                                                        String key)
                                                 throws ValueNotFoundException

The key we are given must refer to an entry in the Map which is a set of lines of the form:
en_GB|Here is some text in English
fr_FR|Voici un texte en français
All the text must fit onto one line. If it does not, we are unlikely to be able to cope since lines will be retrieved from the Set in an almost random order. Also if you specify the same locale on two or more lines, only one can be added to the map (a random one due to the random order - although you will get a warning. Caveat administrator.

Parameters:

map - The map of strings (keys) to sets of strings

key - The key to use to access the map

Returns:

A map of locales to localized text.

Throws:

ValueNotFoundException - if the set of values we need are not present

Gets a boolean attribute from a Map<String, Set<String>>, defaulting to the given default value if the attribute is not present.

Parameters:

Parameters:

map - the attribute map.

name - the name of the attribute to retrieve.

Returns:

the boolean value using Boolean.parseBoolean(String).

Returns the first attribute value for the corresponding name in the config map and parses it to a long.

Parameters:

config - The map where the attribute should be retrieved from.

name - The name of the attribute that should be retrieved from the map.

Returns:

getServerMapAttr

public static String getServerMapAttr(Map map,
                                      String attrName)

This convenience method is for getting server specific attributes from a list attribute. Server specific is determined by prefixing a list attribute value with DSAME local server name followed by the | character. If the list has more than one entry but no matching local server prefixes than null is returned as this is an invalid configuration for these type of attributes. This allows services like authentication to support a geographic directory configuration.

Parameters:

map - Map of String of Set of String.

attrName - Key of the map entry of interest.

Returns:

the server name.

getServerMapAttrs

public static Set<String> getServerMapAttrs(Map<String,Set<String>> map,
                                            String attrName)

This convenience method is for getting server specific attributes from a list attribute. Server specific is determined by prefixing a list attribute value with DSAME local server name followed by the | character. The priority order of the attributes as follows. 1- LDAP Servers belong to current OpenAM Server, localDsameServer is prefixed with the attribute 2- LDAP Servers belong to no OpenAM Server, no server prefix 3- All other servers - LDAP Servers prefixed with other OpenAM Servers This allows services like authentication to support a geographic directory configuration.

Parameters:

map - Map of String of Set of String.

attrName - Key of the map entry of interest.

Returns:

attributes based on the prioritization.
