brave.NoopSpanCustomizer

All Implemented Interfaces:

SpanCustomizer, Serializable, Comparable<NoopSpanCustomizer>

public enum NoopSpanCustomizer
extends Enum<NoopSpanCustomizer>
implements SpanCustomizer

Performs no operations as the span represented by this is not sampled to report to the tracing system.

public static final NoopSpanCustomizer INSTANCE

Method Detail

values

public static NoopSpanCustomizer[] 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 (NoopSpanCustomizer c : NoopSpanCustomizer.values())
    System.out.println(c);

Returns:

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

valueOf

public static NoopSpanCustomizer 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

name

public SpanCustomizer name(String name)

Description copied from interface: SpanCustomizer

Sets the string name for the logical operation this span represents.

Specified by:

name in interface SpanCustomizer

tag

public SpanCustomizer tag(String key,
                          String value)

Description copied from interface: SpanCustomizer

Tags give your span context for search, viewing and analysis. For example, a key "your_app.version" would let you lookup spans by version. A tag "sql.query" isn't searchable, but it can help in debugging when viewing a trace.

Note:To guard potentially expensive parsing, implement Tag instead, which avoids parsing into a no-op span.

Ex.

{@code
 SUMMARY_TAG = new Tag("summary") {

Specified by:

tag in interface SpanCustomizer

Parameters:

key - Name used to lookup spans, such as "your_app.version".

value - String value, cannot be null.

Tag.tag(Object, SpanCustomizer)

annotate

public SpanCustomizer annotate(String value)

Description copied from interface: SpanCustomizer

Associates an event that explains latency with the current system time.

Specified by:

annotate in interface SpanCustomizer

Parameters:

value - A short tag indicating the event, like "finagle.retry"

toString

public String toString()

Overrides:

toString in class Enum<NoopSpanCustomizer>
