Class GenericBrowserSettings

  • All Implemented Interfaces:
    BrowserSettings, EnumBrowserType
    Direct Known Subclasses:
    AbstractBrowserSettings, HttpBrowserSettings
    public abstract class GenericBrowserSettings
extends java.lang.Object
implements BrowserSettings
    This abstract class represents a generic implementation of the BrowserSettings interface.

    It provides with implementation of methods that can be used on other BrowserSettings child classes. Some of these methods are the ones that provide a cache system for the values (addCacheValue(), getCacheValue(), etc); others for values related to the Query String and Form Data (buildBrowserSettingURLParameter(), getValueFromQueryString(), etc); and generic methods for finding out information about the client browser that made a request (isDHTMLSupported(), getBrowserType(), etc)

    As mentioned above, this implementation provides a cache system that can be used transparently by the classes that extend this implementation. It is assumed that the values saved under the main keys are with URL-like format, for example:
    key1=subkey1=value1&subkey2=value2
    This formatting is completely hidden if using the cache methods. If the cache does not exist then the updateCacheValue() method can be directly used and this one will create the cache and will provide the URL-like string required to be saved as the value of a cookie, a preference, or any other.
