validateHeaderValue0

add

public HttpHeaders add(String name,
 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(String name,
 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,
 String name,
 String value)

remove

public HttpHeaders remove(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,
 String name)

set

public HttpHeaders set(String name,
 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(String name,
 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:

set in class HttpHeaders

Parameters:

name - The name of the headers being set

values - The values of the headers being set

Returns:

this

clear

public HttpHeaders clear()

Description copied from class: HttpHeaders

Removes all headers from this HttpMessage.

Specified by:

clear in class HttpHeaders

Returns:

this

get

public String get(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

get

private String get(String name,
 boolean last)

getAll

public List<String> getAll(String name)

Description copied from class: HttpHeaders

Returns the values of headers with the specified name

Specified by:

getAll in class HttpHeaders

Parameters:

name - The name of the headers to search

Returns:

A List of header values which will be empty if no values are found

entries

public List<Map.Entry<String,String>> entries()

Description copied from class: HttpHeaders

Returns a new List that contains all headers in this object. Note that modifying the returned List will not affect the state of this object. If you intend to enumerate over the header entries only, use Iterable.iterator() instead, which has much less overhead.

Specified by:

entries in class HttpHeaders

iterator

public Iterator<Map.Entry<String,String>> iterator()

contains

public boolean contains(String name)

Description copied from class: HttpHeaders

Checks to see if there is a header with the specified name

Specified by:

contains in class HttpHeaders

name - The name of the header to search for

Returns:

True if at least one header is found

isEmpty

public boolean isEmpty()

Description copied from class: HttpHeaders

Checks if no header exists.

Specified by:

isEmpty in class HttpHeaders

contains

public boolean contains(String name,
 String value,
 boolean ignoreCaseValue)

Description copied from class: HttpHeaders

Returns true if a header with the name and value exists.

Overrides:

contains in class HttpHeaders

Parameters:

name - the headername

value - the value

ignoreCaseValue - true if case should be ignored

Returns:

contains true if it contains it false otherwise

names

public Set<String> names()

Description copied from class: HttpHeaders

Returns a new Set that contains the names of all headers in this object. Note that modifying the returned Set will not affect the state of this object. If you intend to enumerate over the header entries only, use Iterable.iterator() instead, which has much less overhead.

Specified by:

names in class HttpHeaders

toString

private static String toString(Object value)
