Enum Constant Detail

DROP

public static final SamplingDecision DROP

Span is dropped. The resulting span will be completely no-op.

RECORD_ONLY

public static final SamplingDecision RECORD_ONLY

Span is recorded only. The resulting span will record all information like timings and attributes but will not be exported. Downstream parent-based samplers will not sample the span.

RECORD_AND_SAMPLE

public static final SamplingDecision RECORD_AND_SAMPLE

Span is recorded and sampled. The resulting span will record all information like timings and attributes and will be exported.

Method Detail

values

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

Returns:

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

valueOf

public static SamplingDecision 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
