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

Overrides default org.eclipse.jetty.http.HttpFields.Mutable.computeField.

Doc from org.eclipse.jetty.http.HttpFields.Mutable.computeField.

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);
Parameters
header:HttpHeader

the field name

computeFn:BiFunction<HttpHeader, List<HttpField>, HttpField>

the compute function

Returns:HttpFields.Mutable

private void copyImmutable()
equalsback to summary
public boolean equals(Object o)

Overrides java.lang.Object.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
o:Object

the reference object with which to compare.

Returns:boolean

true if this object is the same as the obj argument; false otherwise.

Doc from org.eclipse.jetty.http.HttpFields.getField.

Returns the first HttpField with the given field name, or null if no such field is present.

The comparison of field name is case-insensitive via HttpField#is(String).

Parameters
name:String

the case-insensitive field name to search for

Returns:HttpField

the first HttpField with the given field name, or null if no such field is present

Annotations
@Override
hashCodeback to summary
public int hashCode()

Overrides java.lang.Object.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
Returns:int

a hash code value for this object

public void add(HttpField field)

Implements java.util.ListIterator.add.
