add

public HttpHeaders add(java.lang.String name,
                       java.lang.Object value)

Description copied from class: HttpHeaders

Adds a new header with the specified name and value. If the specified value is not a String, it is converted into a String by Object.toString(), except in the cases of Date and Calendar, which are formatted to the date format defined in RFC2616.

Specified by:

add in class HttpHeaders

Parameters:

name - The name of the header being added

value - The value of the header being added

Returns:

this

add

public HttpHeaders add(java.lang.String name,
                       java.lang.Iterable<?> values)

Description copied from class: HttpHeaders

Adds a new header with the specified name and values. This getMethod can be represented approximately as the following code:

 for (Object v: values) {
     if (v == null) {
         break;
     }
     headers.add(name, v);
 }
 

Specified by:

add in class HttpHeaders

Parameters:

name - The name of the headers being set

values - The values of the headers being set

Returns:

this

add0

private void add0(int h,
                  int i,
                  java.lang.String name,
                  java.lang.String value)

remove

public HttpHeaders remove(java.lang.String name)

Description copied from class: HttpHeaders

Removes the header with the specified name.

Specified by:

remove in class HttpHeaders

Parameters:

name - The name of the header to remove

Returns:

this

remove0

private void remove0(int h,
                     int i,
                     java.lang.String name)

set

public HttpHeaders set(java.lang.String name,
                       java.lang.Object value)

Description copied from class: HttpHeaders

Sets a header with the specified name and value. If there is an existing header with the same name, it is removed. If the specified value is not a String, it is converted into a String by Object.toString(), except for Date and Calendar, which are formatted to the date format defined in RFC2616.

Specified by:

set in class HttpHeaders

Parameters:

name - The name of the header being set

value - The value of the header being set

Returns:

this

set

public HttpHeaders set(java.lang.String name,
                       java.lang.Iterable<?> values)

Description copied from class: HttpHeaders

Sets a header with the specified name and values. If there is an existing header with the same name, it is removed. This getMethod can be represented approximately as the following code:

 headers.remove(name);
 for (Object v: values) {
     if (v == null) {
         break;
     }
     headers.add(name, v);
 }
 

Specified by:

get

public java.lang.String get(java.lang.String name)

Description copied from class: HttpHeaders

Returns the value of a header with the specified name. If there are more than one values for the specified name, the first value is returned.

Specified by:

get in class HttpHeaders

Parameters:

name - The name of the header to search

Returns:

The first header value or null if there is no such header
