computeField

public HttpFields.Mutable computeField(HttpHeader header,
 BiFunction<HttpHeader,List<HttpField>,HttpField> computeFn)

Description copied from interface: HttpFields.Mutable

Computes a single field for the given HttpHeader and for existing fields with the same header.

The compute function receives the field name and a list of fields with the same name so that their values can be used to compute the value of the field that is returned by the compute function parameter. If the compute function returns null, the fields with the given name are removed.

This method comes handy when you want to add an HTTP header if it does not exist, or add a value if the HTTP header already exists, similarly to Map.compute(Object, BiFunction).

This method can be used to put a new field (or blindly replace its value):

 httpFields.computeField("X-New-Header",
     (name, fields) -> new HttpField(name, "NewValue"));
 

This method can be used to coalesce many fields into one:

 // Input:
 GET / HTTP/1.1
 Host: localhost
 Cookie: foo=1
 Cookie: bar=2,baz=3
 User-Agent: Jetty

 // Computation:
 httpFields.computeField("Cookie", (name, fields) ->
 {
     // No cookies, nothing to do.
     if (fields == null)
         return null;

     // Coalesces all cookies.
     String coalesced = fields.stream()
         .flatMap(field -> Stream.of(field.getValues()))
         .collect(Collectors.joining(", "));

     // Returns a single Cookie header with all cookies.
     return new HttpField(name, coalesced);
 }

 // Output:
 GET / HTTP/1.1
 Host: localhost
 Cookie: foo=1, bar=2, baz=3
 User-Agent: Jetty
 

This method can be used to replace a field:

 httpFields.computeField("X-Length", (name, fields) ->
 {
     if (fields == null)
         return null;

     // Get any value among the X-Length headers.
     String length = fields.stream()
         .map(HttpField::getValue)
         .findAny()
         .orElse("0");

     // Replace X-Length headers with X-Capacity header.
     return new HttpField("X-Capacity", length);
 });
 

This method can be used to remove a field:

 httpFields.computeField("Connection", (name, fields) -> null);
 

Specified by:

computeField in interface HttpFields.Mutable

Parameters:

header - the field name

computeFn - the compute function

Returns:

this instance

 BiFunction<String,List<HttpField>,HttpField> computeFn)
