Constructor Summary

ContextContainer(java.lang.String _id, ContextContainer _parent)
Since a ContextContainer can contain other ContextContainer, it has to know which ContextContainer contains this.

Method Summary

boolean	containsKey(java.lang.Object key)
boolean	containsKey(java.lang.String key)
boolean	containsKey(java.lang.String key, boolean checkParent) Like the containsKey of HashMap.
java.lang.Object	get(java.lang.String key)
java.lang.Object	get(java.lang.String key, boolean checkParent) Like get, but you can explicity indicate if to search 'parent' Contextes as well
java.util.Set	keySet()
java.lang.Object	put(java.lang.Object key, java.lang.Object value) Keys must be Strings, so put(Object, ..) is forbidden in this HashMap!
java.lang.Object	put(java.lang.String key, java.lang.Object value) Not all Strings can be allowed as keys.

Constructor Detail

ContextContainer

public ContextContainer(java.lang.String _id,
                        ContextContainer _parent)

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

Method Detail

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!

Overrides:

put in class java.util.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.

containsKey

public boolean containsKey(java.lang.Object key)

Overrides:

containsKey in class java.util.HashMap

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).

containsKey

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

get

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

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

get

public java.lang.Object get(java.lang.String key)
                     throws javax.servlet.jsp.JspTagException

keySet

public java.util.Set keySet()

Overrides:

keySet in class java.util.HashMap
