Uses of FlowMetrics in cloud.opencode.base.flow.observability

Classes in cloud.opencode.base.flow.observability that implement FlowMetrics

Modifier and Type	Class	Description
final class	BaseObservabilityFlowMetrics	FlowMetrics adapter that forwards every event into a MetricRegistry from opencode-base-observability.
final class	NoOpFlowMetrics	Zero-cost default FlowMetrics — every method is an empty body.

Methods in cloud.opencode.base.flow.observability that return FlowMetrics

Modifier and Type	Method	Description
static FlowMetrics	FlowMetricsFactory.create()	Returns a FlowMetrics bound to a freshly created MetricRegistry when opencode-base-observability is on the classpath, or a NoOpFlowMetrics otherwise.
static FlowMetrics	FlowMetricsFactory.fromRegistry(Object registry)	Returns a FlowMetrics bound to the supplied registry.
