public Object get(String key)

Gets a value. Valid value types are String, Boolean, and Number implementations.

Parameters

key	the value to get

Returns

the data for the value

Gets a value and converts it to a Boolean.

Parameters

key	the value to get

Returns

the Boolean value, or null if the value is missing or cannot be converted
