All Implemented Interfaces:

java.lang.Cloneable, java.util.Map, java.io.Serializable

public class ContextContainer

extends java.util.HashMap

This is a HashMap, but the keys can contain 'dots', in which case there is searched for HashMaps in the HashMap.

Constructor Detail

ContextContainer

public ContextContainer(java.lang.String i,
                        ContextContainer p)

Since a ContextContainer can contain other ContextContainer, it has to know which ContextContainer contains this. And it also has an id.

Method Detail

stringToLocation

public static int stringToLocation(java.lang.String s)
                            throws javax.servlet.jsp.JspTagException

Throws:

javax.servlet.jsp.JspTagException

locationToString

public static java.lang.String locationToString(int i)

getId

public java.lang.String getId()

put

public java.lang.Object put(java.lang.Object key,
                            java.lang.Object value)

Keys must be Strings, so put(Object, ..) is forbidden in this HashMap!

put

public java.lang.Object put(java.lang.String key,
                            java.lang.Object value)
                     throws javax.servlet.jsp.JspTagException

Not all Strings can be allowed as keys. Keys are like variable names.

Throws:

javax.servlet.jsp.JspTagException

containsKey

public boolean containsKey(java.lang.Object key)

containsKey

public boolean containsKey(java.lang.String key,
                           boolean checkParent)
                    throws javax.servlet.jsp.JspTagException

Like the containsKey of HashMap.

Parameters:

key - The key to search

checkParent - If this is false, it will only look in the current Container (and below).

Throws:

javax.servlet.jsp.JspTagException

                            boolean checkParent)
                     throws javax.servlet.jsp.JspTagException

Like get, but you can explicity indicate if to search 'parent' Contextes as well.

Throws:

javax.servlet.jsp.JspTagException

get

                                throws TaglibException

Java Servlet Specification Version 2.3 SRV.4.9 says that a servlet engine should read a request as ISO-8859-1 if request.getCharacterEncoding() returns null. We override this behaviour because the browser propably sends the request in the same encoding as the html was send to te browser
