Constructor Details

Builder

public Builder(InMemoryScopeManager scopeManager)

Constructs a builder for an DefaultInMemoryTracer.

Parameters:

scopeManager - a InMemoryScopeManager.

Method Details

withSampler

public DefaultInMemoryTracer.Builder withSampler(Predicate<String> sampler)

Sets the sampler.

Parameters:

sampler - policy which takes a traceId and returns whether the given trace should be sampled

Returns:

this

withSampler

public DefaultInMemoryTracer.Builder withSampler(BiFunction<String,Boolean,Boolean> sampler)

Sets the sampler.

Parameters:

sampler - policy which takes a traceId and the sampling flag specified in carrier (optional, could be null), and returns whether the given trace should be sampled.

Returns:

this

addListener

public DefaultInMemoryTracer.Builder addListener(InMemorySpanEventListener listener)

Add a trace event listener.

Parameters:

listener - listener to add

Returns:

this

withMaxTagSize

public DefaultInMemoryTracer.Builder withMaxTagSize(int maxTagSize)

Sets the maximum number of tags.

Parameters:

maxTagSize - maximum number of tags

Returns:

this

persistLogs

public DefaultInMemoryTracer.Builder persistLogs(boolean persistLogs)

Sets whether logs are persisted in the span object. This is necessary when using using listeners which sends the span to a backend on span finish.

Parameters:

persistLogs - whether to persist logs in the span object. Defaults to false.

Returns:

this

use128BitTraceId

public DefaultInMemoryTracer.Builder use128BitTraceId(boolean use128BitTraceId)

Sets whether to use 128-bit trace IDs.

Parameters:

use128BitTraceId - whether to use 128-bit trace IDs.

Returns:

this
