SessionProtocol (filter-service-metrics 1.13 1.13 API)

java.lang.Object
- java.lang.Enum<SessionProtocol>
- - com.linecorp.armeria.common.SessionProtocol

All Implemented Interfaces:

Serializable, Comparable<SessionProtocol>
```
public enum SessionProtocol
extends Enum<SessionProtocol>
```
Session-level protocol that provides facilities such as framing and flow control.

Method Summary

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`int`	`defaultPort()` Returns the default INET port number of this protocol.
`static SessionProtocol`	`find(String uriText)` Finds the `SessionProtocol` with the specified `uriText()`.
`static Set<SessionProtocol>`	`httpsValues()` Returns an immutable `Set` that contains `HTTPS`, `H1` and `H2`.
`static Set<SessionProtocol>`	`httpValues()` Returns an immutable `Set` that contains `HTTP`, `H1C` and `H2C`.
`boolean`	`isMultiplex()` Returns `true` if and only if this protocol can multiplex a single transport-layer connection into more than one stream.
`boolean`	`isTls()` Returns `true` if and only if this protocol uses TLS as its transport-level security layer.
`static SessionProtocol`	`of(String uriText)` Returns the `SessionProtocol` with the specified `uriText()`.
`String`	`toString()`
`String`	`uriText()` Returns the textual representation of this format for use in a `Scheme`.
`static SessionProtocol`	`valueOf(String name)` Returns the enum constant of this type with the specified name.
`static SessionProtocol[]`	`values()` Returns an array containing the constants of this enum type, in the order they are declared.

- Method Detail
  - values
```
public static SessionProtocol[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (SessionProtocol c : SessionProtocol.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static SessionProtocol valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - of
```
public static SessionProtocol of(String uriText)
```
    Returns the SessionProtocol with the specified uriText().
    
    Throws:
    
    IllegalArgumentException - if there's no such SessionProtocol
  - find
```
public static SessionProtocol find(String uriText)
```
    Finds the SessionProtocol with the specified uriText().
  - httpValues
```
public static Set<SessionProtocol> httpValues()
```
    Returns an immutable Set that contains HTTP, H1C and H2C. Note that it does not contain HTTPS protocols such as HTTPS, H1 and H2.
    
    See Also:
    
    httpsValues()
  - httpsValues
```
public static Set<SessionProtocol> httpsValues()
```
    Returns an immutable Set that contains HTTPS, H1 and H2. Note that it does not contain HTTP protocols such as HTTP, H1C and H2C.
    
    See Also:
    
    httpValues()
  - isTls
```
public boolean isTls()
```
    Returns true if and only if this protocol uses TLS as its transport-level security layer.
  - uriText
```
public String uriText()
```
    Returns the textual representation of this format for use in a Scheme.
  - isMultiplex
```
public boolean isMultiplex()
```
    Returns true if and only if this protocol can multiplex a single transport-layer connection into more than one stream.
  - defaultPort
```
public int defaultPort()
```
    Returns the default INET port number of this protocol.
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Enum<SessionProtocol>
