All Implemented Interfaces:

Comparable<Snowflake>

public final class Snowflake
extends Object
implements Comparable<Snowflake>

An unsigned 64-bit ID that is guaranteed to be unique across all of Discord, except in some unique scenarios in which child objects share their parent's ID.

Method Detail

of

public static Snowflake of(long id)

Constructs a Snowflake utilizing an unsigned ID.

Parameters:

id - The unsigned ID to construct a Snowflake.

Returns:

A constructed Snowflake with the unsigned ID.

of

public static Snowflake of(String id)

Constructs a Snowflake utilizing an unsigned ID.

Parameters:

id - The unsigned ID to construct a Snowflake. Must be non-null.

Returns:

A constructed Snowflake with the unsigned ID.

Throws:

NumberFormatException - If id is not an unsigned ID.

of

public static Snowflake of(Instant timestamp)

Constructs a Snowflake utilizing a timestamp. The constructed Snowflake is only guaranteed to contain accurate information about its timestamp; the other portions are undefined.

Parameters:

timestamp - The timestamp to construct a Snowflake. Must be non-null.

Returns:

A constructed Snowflake with the timestamp.

of

public static Snowflake of(BigInteger id)

Constructs a Snowflake utilizing a BigInteger representing an unsigned ID.

Parameters:

id - The BigInteger representing an unsigned ID to construct a Snowflake. Must be non-null.

Returns:

A constructed Snowflake with an unsigned ID.

asLong

public long asLong()

Gets the unsigned ID of this Snowflake as a primitive long.

Returns:

The unsigned ID of this Snowflake as a primitive long.

asString

public String asString()

Gets the unsigned ID of this Snowflake as an object String.

Returns:

The unsigned ID of this Snowflake as an object String.

getTimestamp

public Instant getTimestamp()

Gets the timestamp of this Snowflake.

Returns:

The timestamp of this Snowflake.

asBigInteger

public BigInteger asBigInteger()

Gets the unsigned ID of this Snowflake as a BigInteger.

Returns:

The unsigned ID of this Snowflake as a BigInteger.

compareTo

public int compareTo(Snowflake other)

Compares this snowflake to the specified snowflake.

The comparison is based on the timestamp portion of the snowflakes.

Specified by:

compareTo in interface Comparable<Snowflake>

Parameters:

other - The other snowflake to compare to.

Returns:

The comparator value.

equals

public boolean equals(@Nullable
                      Object obj)

Indicates whether some other object is "equal to" this Snowflake. The other object is considered equal if:

• It is also a Snowflake and;
• Both instances have equal IDs.

Overrides:

equals in class Object

Parameters:

obj - An object to be tested for equality.

Returns:

true if the other object is "equal to" this one, false otherwise.

hashCode

public int hashCode()

Gets the hash code value of the ID.

Overrides:

hashCode in class Object

Returns:

The hash code value of the ID.

toString

public String toString()

Gets the String representation of this Snowflake.

The format returned by this method is unspecified and may vary between implementations; however, it is guaranteed to always be non-empty. This method is not suitable for obtaining the ID; use asString() instead.

Overrides:

toString in class Object

Returns:

The String representation of this Snowflake.
