Represents a protocol version, as specified in RFC 2616. More...
RFC 2616 specifies only HTTP versions, like "HTTP/1.1" and "HTTP/1.0". RFC 3261 specifies a message format that is identical to HTTP except for the protocol name. It defines a protocol version "SIP/2.0". There are some nitty-gritty differences between the interpretation of versions in HTTP and SIP. In those cases, HTTP takes precedence.
This class defines a protocol version as a combination of protocol name, major version number, and minor version number. Note that equals and hashCode are defined as final here, they cannot be overridden in derived classes.
The following notice applies to the original API on which this API is based, and to its documentation. The documentation of this API has been revised from the original.

| Name of the protocol. More... | |
| final int | major |
| Major version number of the protocol. | |
| final int | minor |
| Minor version number of the protocol. | |
| ProtocolVersion | ( | String | protocol, |
| int | major, | ||
| int | minor | ||

| int | minor | ||
| ) |
This can be used by derived classes to instantiate themselves instead of the base class, and to define constants for commonly used versions.
The default implementation in this class returns this if the version matches, and creates a new ProtocolVersion otherwise.
| major | the major version |
| minor | the minor version |
Reimplemented in HttpVersion.
| final int hashCode | ( | ) |
| final boolean equals | ( | Object | obj | ) |
The object is equal if it is a protocl version with the same protocol name, major version number, and minor version number. The specific class of the object is not relevant, instances of derived classes with identical attributes are equal to instances of the base class and vice versa.
| obj | the object to compare with |
true if the argument is the same protocol version, false otherwise | boolean isComparable | ( | ProtocolVersion | that | ) |
Only protocol versions with the same protocol name can be compared .
| that | the protocol version to consider |
true if compareToVersion can be called with the argument, false otherwise | int compareToVersion | ( | ProtocolVersion | that | ) |
Only protocol versions with the same protocol name can be compared. This method does not define a total ordering, as it would be required for java.lang.Comparable.
| that | the protocl version to compare with |
| IllegalArgumentException | if the argument has a different protocol name than this object, or if the argument is null |
| final boolean greaterEquals | ( | ProtocolVersion | version | ) |
| version | the version against which to check this version |
true if this protocol version is comparable to the argument and compares as greater or equal, false otherwise | final boolean lessEquals | ( | ProtocolVersion | version | ) |
| version | the version against which to check this version |
true if this protocol version is comparable to the argument and compares as less or equal, false otherwise | String toString | ( | ) |
