YAHOO.util.Config

YAHOO.util.Config ()
Copyright (c) 2006, Yahoo! Inc. All rights reserved. Code licensed under the BSD License: http://developer.yahoo.net/yui/license.txt
Parameters:
owner - The owner object to which this Config object belongs
HASH(0x1d243d8)

Method Detail [top]

addProperty

void addProperty (<string> key, <object> propertyObject)
Adds a property to the Config object's private config hash.
Parameters:
key - The configuration property's name
propertyObject - The object containing all of this property's arguments
HASH(0x1cf51f8)

applyConfig

void applyConfig (<object> userConfig,<boolean> init)
Applies a key-value object literal to the configuration, replacing any existing values, and queueing the property events. Although the values will be set, fireQueue() must be called for their associated events to execute.
Parameters:
userConfig - The configuration object literal
init - When set to true, the initialConfig will be set to the userConfig passed in, so that calling a reset will reset the properties to the passed values.
HASH(0x1cf54e0)

checkBoolean

boolean checkBoolean (<object> val)
Validates that the value passed in is a boolean.
Parameters:
val - The value to validate
Returns:
true, if the value is valid
HASH(0x1d08448)

checkNumber

boolean checkNumber (<object> val)
Validates that the value passed in is a number.
Parameters:
val - The value to validate
Returns:
true, if the value is valid
HASH(0x1d08718)

fireQueue

void fireQueue ()
Fires the normalized list of queued property change events HASH(0x1d24684)

getConfig

object getConfig ()
Returns a key-value configuration map of the values currently set in the Config object.
Returns:
The current config, represented in a key-value map
HASH(0x1d248a0)

getProperty

object getProperty (key)
Returns the value of specified property.
Parameters:
The - name of the property
Returns:
The value of the specified property
HASH(0x1d249e4)

init

void init (<object> owner)
Initializes the configuration object and all of its local members.
Parameters:
owner - The owner object to which this Config object belongs
HASH(0x1d24c78)

queueProperty

boolean queueProperty (key,value)
Sets the value of a property and queues its event to execute. If the event is already scheduled to execute, it is moved from its current position to the end of the queue.
Parameters:
The - name of the property
The - value to set the property to
Returns:
true, if the set was successful, false if it failed.
HASH(0x1d24e58)

refireEvent

void refireEvent (key)
Fires the event for a property using the property's current value.
Parameters:
The - name of the property
HASH(0x1d3f748)

refresh

void refresh ()
Refires the events for all configuration properties using their current values. HASH(0x1d3f9dc)

resetProperty

void resetProperty (key)
Resets the specified property's value to its initial value.
Parameters:
The - name of the property
HASH(0x1d3fd60)

setProperty

boolean setProperty (key,value,silent)
Sets the value of a property. If the silent property is passed as true, the property's event will not be fired.
Parameters:
The - name of the property
The - value to set the property to
Whether - the value should be set silently, without firing the property event.
Returns:
true, if the set was successful, false if it failed.
HASH(0x1d40024)

subscribeToConfigEvent

void subscribeToConfigEvent (<string> key,<Function> handler,<object> obj,<boolean> override)
Subscribes an external handler to the change event for any given property.
Parameters:
key - The property name
handler - The handler function to use subscribe to the property's event
obj - The object to use for scoping the event handler (see CustomEvent documentation)
override - Optional. If true, will override "this" within the handler to map to the scope object passed into the method.
HASH(0x1d413d8)

unsubscribeFromConfigEvent

void unsubscribeFromConfigEvent (<string> key,<Function> handler,<object> obj)
Unsubscribes an external handler from the change event for any given property.
Parameters:
key - The property name
handler - The handler function to use subscribe to the property's event
obj - The object to use for scoping the event handler (see CustomEvent documentation)
HASH(0x1d41780)

alreadySubscribed

boolean alreadySubscribed (<YAHOO.util.CustomEvent> evt, <Function> fn, <object> obj)
