All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.util.Map

Enclosing class:

SegmentedOptionService

protected class SegmentedOptionService.LazySegmentedOptionsMap
extends java.util.HashMap

A Map for SegmentedOptions that waits until get() or containsKey() is called to load the SegmentedOption value into the Map. keyed off the SegmentedOption name. This will allows formhandlers and input/getvalueof tags to use a Map for working with the SegmentedOptions without having to load every SegmentedOption in the system first.

Constructor Detail

SegmentedOptionService.LazySegmentedOptionsMap

public SegmentedOptionService.LazySegmentedOptionsMap(java.lang.String pSegment)

Method Detail

get

public java.lang.Object get(java.lang.Object key)

Gets the site option from the hashmap if it exists. If not it will go out to the repository, load it and put it into the map. This allows formhandlers to just load only the site options that are being edited into the map instead of every map in the system.

Specified by:

get in interface java.util.Map

Overrides:

get in class java.util.HashMap

Parameters:

key - the key whose associated value is to be returned.

Returns:

the value to which this map maps the specified key, or null if the map contains no mapping for this key.

See Also:

HashMap.put(Object, Object)

containsKey

public boolean containsKey(java.lang.Object key)

Returns true if this map contains a mapping for the specified key. If the Map does not contain the given key an attempt is made to load the option from the repository and put it into the map. If the option does not exist in the repository and therefore cannot be loaded into the map false is returned.

Specified by:

containsKey in interface java.util.Map

Overrides:

containsKey in class java.util.HashMap

Parameters:

key - The key whose presence in this map is to be tested

Returns:

true if this map contains a mapping for the specified key.
