Example 1 with TraceStateBuilder

use of io.opentelemetry.api.trace.TraceStateBuilder in project opentelemetry-java by open-telemetry.

the class W3CTraceContextEncoding method decodeTraceState.

/**
 * Decodes a trace state header into a {@link TraceState} object.
 *
 * @throws IllegalArgumentException if {@code traceStateHeader} does not comply with the
 *     specification

    checkArgument(listMembers.length <= TRACESTATE_MAX_MEMBERS, "TraceState has too many elements.");
    // front of the list.
    for (int i = listMembers.length - 1; i >= 0; i--) {
