o
,
f
,
c
,
proto
)
Executes a function on each item. The function
receives the value, the key, and the object
as parameters (in that order).
- Parameters:
-
o <object>the object to iterate. -
f <Function>the function to execute on each item. The function receives three arguments: the value, the the key, the full object. -
c <object>the execution context. -
proto <boolean>include proto.
- Returns:
YUI - the YUI instance.
getValue
static
Any
getValue
(
o

path
)
Retrieves the sub value at the provided path,
from the value object provided.
- Parameters:
-
o <object>The object from which to extract the property value. -
path <Array>A path array, specifying the object traversal path from which to obtain the sub value.
- Returns:
Any - The value stored in the path, undefined if not found, undefined if the source is not an object. Returns the source object if an empty path is provided.
hasKey
static
boolean
hasKey
(

)
Returns true if the object contains a given key
- Parameters:
-
o <object>an object. -
k <object>the key to query.
- Returns:
boolean - true if the object contains the key.
hasValue
static
boolean
hasValue
(
o
,
v
)
Returns true if the object contains a given value
- Parameters:
-
o <object>an object. -
v <object>the value to query.
- Returns:
boolean - true if the object contains the value.
isEmpty
static
boolean
isEmpty
(
)
Returns true if the object has no properties of its own
- Returns:
boolean - true if the object is empty.
keys

to the object instance. Returns false if the property is not present
in the object, or was inherited from the prototype.
- Parameters:
-
o <any>The object being testing. -
p <string>the property to look for.
- Returns:
boolean - true if the object has the property on the instance.
setValue
static
Object
setValue
(
o
,
path
,
val
)
Sets the sub-attribute value at the provided path on the
value object. Returns the modified value object, or
undefined if the path is invalid.
- Parameters:
-
o <object>The object on which to set the sub value. -
path <Array>A path array, specifying the object traversal path at which to set the sub value. -
val <Any>The new value for the sub-attribute.
- Returns:
Object - The modified object, with the new sub value set, or undefined, if the path was invalid.

- Returns:
int - the size.
some
static
boolean
some
(
o
,
f

function returns true. The function
receives the value, the key, and the object
as paramters (in that order).
