Instantiates a new abstract Header-Fields.

Parameters:

aHttpFields - the http fields

Method Detail

get

Overrides:

entrySet in class java.util.HashMap<java.lang.String,java.util.List<java.lang.String>>

put

public java.util.List<java.lang.String> put(java.lang.String aKey,
                                            java.util.List<java.lang.String> aValue)

Specified by:

put in interface java.util.Map<C extends Cookie,T extends HeaderFields<C,T>>

Overrides:

put in class java.util.HashMap<java.lang.String,java.util.List<java.lang.String>>

addTo

public void addTo(java.lang.String aHeaderField,
                  java.lang.String aValue)

Adds a value to the list of values associated with the given Header-Field (key).

Specified by:

addTo in interface HttpFields<C extends Cookie>

Parameters:

aHeaderField - The Header-Field (key) of which's list of values a value is to be added.

aValue - The value to be added to the list of values associated to the given Header-Field (key).

addCookie

public C addCookie(C aCookie)

Adds an individual server-side cookie to be sent to the client to this ResponseHeaderFields instance. The server-side cookies are retrieved from the HeaderField.SET_COOKIE Header-Field. WITH THE METHOD HeaderFields.getAllCookies() and HeaderFields.getCookies(String) as well as HeaderFields.getFirstCookie(String) ONLY THE COOKIES SENT BY THE CLIENT CAN BE RETRIEVED (E.G. COOKIES RESIDING IN THE HEADER FIELD HeaderField.COOKIE). COOKIES SET VIA HeaderFields.addCookie(String, String) OR HeaderFields.withAddCookie(String, String) CANNOT BE RETRIEVED, AS THE COOKIES BEING SET SERVER-SIDE ARE PUT IN THE HeaderField.SET_COOKIE Header-Field.

Specified by:

addCookie in interface HeaderFields<C extends Cookie,T extends HeaderFields<C,T>>

Parameters:

aCookie - The cookie to be added.

Returns:

The resulting cookie builder being added which can be modified affecting(!) this ResponseHeaderFields instance!

getAllCookies

public java.util.List<C> getAllCookies()

Retrieves an array of cookies sent by the client stored in this RequestHeaderFields instance. If no cookie has been found, then an empty array is returned. The client-side cookies are retrieved from the HeaderField.COOKIE Header-Field. WITH THE METHOD HeaderFields.getAllCookies() and HeaderFields.getCookies(String) as well as HeaderFields.getFirstCookie(String) ONLY THE COOKIES SENT BY THE CLIENT CAN BE RETRIEVED (E.G. COOKIES RESIDING IN THE HEADER FIELD HeaderField.COOKIE). COOKIES SET VIA HeaderFields.addCookie(String, String) OR HeaderFields.withAddCookie(String, String) CANNOT BE RETRIEVED, AS THE COOKIES BEING SET SERVER-SIDE ARE PUT IN THE HeaderField.SET_COOKIE Header-Field. According to the Netscape cookie_spec (https://curl.haxx.se/rfc/cookie_spec.html) the entire NAME=VALUE string of a cookie is a sequence of characters excluding semi-colon, comma and white space.

Specified by:

getAllCookies in interface HeaderFields<C extends Cookie,T extends HeaderFields<C,T>>

Returns:

An array containing the cookies (key/value) stored in this RequestHeaderFields instance.

addCookie

public C addCookie(java.lang.String aCookieName,
                   java.lang.String aValue)

Adds an individual server-side cookie to be sent to the client to this ResponseHeaderFields instance. The server-side cookies are retrieved from the HeaderField.SET_COOKIE Header-Field. WITH THE METHOD HeaderFields.getAllCookies() and HeaderFields.getCookies(String) as well as HeaderFields.getFirstCookie(String) ONLY THE COOKIES SENT BY THE CLIENT CAN BE RETRIEVED (E.G. COOKIES RESIDING IN THE HEADER FIELD HeaderField.COOKIE). COOKIES SET VIA HeaderFields.addCookie(String, String) OR HeaderFields.withAddCookie(String, String) CANNOT BE RETRIEVED, AS THE COOKIES BEING SET SERVER-SIDE ARE PUT IN THE HeaderField.SET_COOKIE Header-Field.

Specified by:

addCookie in interface HeaderFields<C extends Cookie,T extends HeaderFields<C,T>>

Parameters:

aCookieName - The name for the cookie to be added.

aValue - The value of the cookie to be added.

Returns:

The resulting cookie builder being added which can be modified affecting(!) this ResponseHeaderFields instance!

putAll

public void putAll(java.util.Map<? extends java.lang.String,? extends java.util.List<java.lang.String>> aMap)

Specified by:

putAll in interface java.util.Map<C extends Cookie,T extends HeaderFields<C,T>>

Overrides:

putAll in class java.util.HashMap<java.lang.String,java.util.List<java.lang.String>>

Parameters:

aHeaderName - The name of the header to be tested.

Returns:

True if the value being held by the given Header-Field name is a comma separated list.

toHeaderFields

protected static void toHeaderFields(java.util.Map<java.lang.String,java.util.List<java.lang.String>> aFromFields,

Parameters:

aHeaderField - The field to normalize.

Returns:

The Header-Field, in case of normalization the normalized one.

getCookieFieldName

protected abstract java.lang.String getCookieFieldName()
