java.util.HashMap<java.lang.String,java.lang.Object>

psdi.webclient.system.controller.LabelCache

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.util.Map<java.lang.String,java.lang.Object>

@TraceDisabled
public class LabelCache
extends java.util.HashMap<java.lang.String,java.lang.Object>

This class is used to cache all of the id/property values for a single app instance. The getCacheKey method should always be used to get a single unique key for this object when it is added to a hashmap

Constructor Detail

LabelCache

public LabelCache(int initialCapacity,
                  float loadFactor,
                  java.lang.String anapp)

Constructor taking both hash map sizing parameters (initialCapacity, loadFactor).

Parameters:

initialCapacity - The initial capacity

loadFactor - The load factor

anapp - Application the cache is for

See Also:

HashMap

LabelCache

public LabelCache(int initialCapacity,
                  java.lang.String anapp)

Constructor taking HashMap initial capacity

Parameters:

initialCapacity - The initial capacity

alocale - Locale the cache is for

anapp - Application the cache is for

atype - Type of labels in the cache

See Also:

HashMap

LabelCache

public LabelCache(java.lang.String anapp)

Constructor using default HashMap values

Parameters:

alocale - Locale the cache is for

anapp - Application the cache is for

atype - Type of labels in the cache

See Also:

HashMap

Method Detail

makeUniqueKey

public static java.lang.String makeUniqueKey(java.lang.String id,
                                             java.lang.String property)

Makes a concatenated key for control id/property pairs. Necessary since hashmaps only take a single key and we need to have the 'primary key' be both the control id and the property.

Parameters:

id - control id for the property

property - name of the property

Returns:

a unique key

getCacheApp

public java.lang.String getCacheApp()

Returns the application this cache is for

Returns:

The application

getCacheCreateDate

public java.util.Date getCacheCreateDate()

Returns the data/time this cache was created

Returns:

The creation date/time

put

public java.lang.Object put(java.lang.String id,
                            java.lang.String property,
                            java.lang.Object value)

Put method added to take the two keys and the value. A single unique key is generated before putting the value into this hashmap. The base 'HashMap.put' method should not be used on the class.

Parameters:

id - Control id

property - Control Property

value - The value to be added to the hashmap

Returns:

the return value from HashMap.put

remove

public java.lang.Object remove(java.lang.String id,
                               java.lang.String property)

get

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

Fetches the string value for control id/property.

Parameters:

key - Control key

Returns:

Value for the property, or null if not found or not a String

getString

public java.lang.String getString(java.lang.String id,
                                  java.lang.String property)

Fetches the string value for control id/property.

Parameters:

id - Control id

property - Control Property

Returns:

Value for the property, or null if not found or not a String

isModified

public boolean isModified()

Returns true of cache was modified

setModified

public void setModified(boolean modified)

Sets the cache to be modified or not
