Enum SpanBytesDecoder

java.lang.Object

java.lang.Enum<SpanBytesDecoder>

zipkin2.codec.SpanBytesDecoder

All Implemented Interfaces:

Serializable, Comparable<SpanBytesDecoder>, BytesDecoder<Span>

public enum SpanBytesDecoder
extends Enum<SpanBytesDecoder>
implements BytesDecoder<Span>

This is separate from SpanBytesEncoder, as it isn't needed for instrumentation

Method Details

values

public static SpanBytesDecoder[] values()

Returns an array containing the constants of this enum type, in the order they are declared.

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static SpanBytesDecoder 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

decodeList

public abstract boolean decodeList(ByteBuffer spans,
 Collection<Span> out)

ByteBuffer implementation of BytesDecoder.decodeList(byte[]).

Note: only use this when it is ok to modify the underlying ByteBuffer.array().

decodeList

public abstract List<Span> decodeList(ByteBuffer spans)

ByteBuffer implementation of BytesDecoder.decodeList(byte[]).

Note: only use this when it is ok to modify the underlying ByteBuffer.array().

decodeOne

@Nullable
public abstract Span decodeOne(ByteBuffer span)

ByteBuffer implementation of BytesDecoder.decodeOne(byte[])

Note: only use this when it is ok to modify the underlying ByteBuffer.array().
