java.lang.Object

java.lang.Record

io.helidon.webserver.ProxyProtocolV2Data.Tlv.Crc32c

Record Components:

checksum - The CRC32c checksum, validated by Helidon.

All Implemented Interfaces:

ProxyProtocolV2Data.Tlv

Enclosing interface:

ProxyProtocolV2Data.Tlv

public static record ProxyProtocolV2Data.Tlv.Crc32c(int checksum)
extends Record
implements ProxyProtocolV2Data.Tlv

The value of the type PP2_TYPE_CRC32C is a 32-bit number storing the CRC32c checksum of the PROXY protocol header. If this TLV is present, Helidon will validate the checksum and reject connections which fail the check.

Constructor Details

Crc32c

public Crc32c(int checksum)

Creates an instance of a Crc32c record class.

Parameters:

checksum - the value for the checksum record component

Method Details

type

public int type()

Description copied from interface: ProxyProtocolV2Data.Tlv

Returns the TLV's type identifier.

Specified by:

type in interface ProxyProtocolV2Data.Tlv

Returns:

The type identifier.

toString

public String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with '=='.

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

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

checksum

public int checksum()

Returns the value of the checksum record component.

Returns:

the value of the checksum record component
