private final Record AltSvcProcessor.HostPort

extends Record
Class Inheritance
Record Components
host:String 
port:int 

Field Summary

Modifier and TypeField and Description
private final String
host

Record Component accessed by host().

private final int
port

Record Component accessed by port().

Constructor Summary

AccessConstructor and Description
private
HostPort(String host, int port)

Method Summary

Modifier and TypeMethod and Description
public final boolean
equals(Object o)

Implements abstract java.lang.Record.equals.

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

public final int
hashCode()

Implements abstract java.lang.Record.hashCode.

Returns a hash code value for the record.

public String
host()

Record Component getter of host.

public int
port()

Record Component getter of port.

public final String
toString()

Implements abstract java.lang.Record.toString.

Returns a string representation of the record.

Field Detail

hostback to summary
private final String host

private final int port

private HostPort(String host, int port)

Method Detail

equalsback to summary
public final boolean equals(Object o)

Implements abstract java.lang.Record.equals.

Doc from java.lang.Record.equals.

Indicates whether some other object is "equal to" this one. In addition to the general contract of Object.equals, record classes must further obey the invariant that when a record instance is "copied" by passing the result of the record component accessor methods to the canonical constructor, as follows: 

    R copy = new R(r.c1(), r.c2(), ..., r.cn());
then it must be the case that r.equals(copy).
hashCodeback to summary
public final int hashCode()

Implements abstract java.lang.Record.hashCode.

Doc from java.lang.Record.hashCode.

Returns a hash code value for the record. Obeys the general contract of Object.hashCode. For records, hashing behavior is constrained by the refined contract of Record.equals, so that any two records created from the same components must have the same hash code.

hostback to summary
public String host()

Record Component getter of host.

portback to summary
public int port()

Record Component getter of port.

toStringback to summary
public final String toString()

Implements abstract java.lang.Record.toString.

Doc from java.lang.Record.toString.

Returns a string representation of the record. In accordance with the general contract of Object#toString(), the toString method returns a string that "textually represents" this record. The result should be a concise but informative representation that is easy for a person to read.

In addition to this general contract, record classes must further participate in the invariant that any two records which are equal must produce equal strings. This invariant is necessarily relaxed in the rare case where corresponding equal component values might fail to produce equal strings for themselves.
