Class Symbol

java.lang.Object

org.apache.qpid.protonj2.types.Symbol

All Implemented Interfaces:

Comparable<Symbol>

public final class Symbol
extends Object
implements Comparable<Symbol>

Class that represents an AMQP Symbol value. The creation of a Symbol object occurs during a lookup operation which cannot find an already stored version of the string or byte buffer view of the Symbol's ASCII bytes.

Method Summary

static Symbol	getSymbol(ProtonBuffer symbolBytes)	Look up a singleton Symbol instance that matches the given ProtonBuffer byte view of the Symbol.
static Symbol	getSymbol(ProtonBuffer symbolBuffer, boolean copyOnCreate)	Look up a singleton Symbol instance that matches the given ProtonBuffer byte view of the Symbol.
int	hashCode()
String	toString()
static Symbol	valueOf(String symbolVal)	Look up a singleton Symbol instance that matches the given String name of the Symbol.

Method Detail

getLength

public int getLength()

Returns:

the number of bytes that comprise the Symbol value.

compareTo

public int compareTo(Symbol other)

Specified by:

compareTo in interface Comparable<Symbol>

toString

public String toString()

Overrides:

toString in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object other)

Overrides:

equals in class Object

writeTo

public void writeTo(ProtonBuffer target)

Writes the internal Symbol bytes to the provided ProtonBuffer. This is a raw ASCII encoding of the Symbol without and AMQP type encoding.

Parameters:

target - The buffer where the Symbol bytes should be written to.

valueOf

public static Symbol valueOf(String symbolVal)

Look up a singleton Symbol instance that matches the given String name of the Symbol.

Parameters:

symbolVal - The String version of the Symbol value.

Returns:

a Symbol that matches the given String.

getSymbol

public static Symbol getSymbol(ProtonBuffer symbolBytes)

Look up a singleton Symbol instance that matches the given ProtonBuffer byte view of the Symbol.

Parameters:

symbolBytes - The String version of the Symbol value.

Returns:

a Symbol that matches the given String.

getSymbol

public static Symbol getSymbol(ProtonBuffer symbolBuffer,
                               boolean copyOnCreate)

Look up a singleton Symbol instance that matches the given ProtonBuffer byte view of the Symbol.

Parameters:

symbolBuffer - The ProtonBuffer version of the Symbol value.

copyOnCreate - Should the provided buffer be copied during creation of a new Symbol.

Returns:

a Symbol that matches the given String.

getSymbol

public static Symbol getSymbol(String stringValue)

Look up a singleton Symbol instance that matches the given String name of the Symbol.

Parameters:

stringValue - The String version of the Symbol value.

Returns:

a Symbol that matches the given String.
