Constructor Details

ServerRequestObservationContext

public ServerRequestObservationContext(ServerHttpRequest request,
 ServerHttpResponse response,
 Map<String,Object> attributes)

Create a new ServerRequestObservationContext instance.

Parameters:

request - the current request

response - the current response

attributes - the current attributes

Method Details

getAttributes

public Map<String,Object> getAttributes()

Return an immutable map of the current request attributes.

getPathPattern

@Nullable
public String getPathPattern()

Return the path pattern for the handler that matches the current request. For example, "/projects/{name}".

Path patterns must have a low cardinality for the entire application.

Returns:

the path pattern, or null if none found

setPathPattern

public void setPathPattern(@Nullable
 String pathPattern)

Set the path pattern for the handler that matches the current request.

Path patterns must have a low cardinality for the entire application.

Parameters:

pathPattern - the path pattern, for example "/projects/{name}".

isConnectionAborted

public boolean isConnectionAborted()

Whether the current connection was aborted by the client, resulting in a cancel signal on the reactive chain, or an AbortedException when reading the request.

Returns:

if the connection has been aborted

setConnectionAborted

public void setConnectionAborted(boolean connectionAborted)

Set whether the current connection was aborted by the client, resulting in a cancel signal on the reactive chain, or an AbortedException when reading the request.

Parameters:

connectionAborted - if the connection has been aborted

findCurrent

public static Optional<ServerRequestObservationContext> findCurrent(Map<String,Object> attributes)

Get the current observation context from the given attributes, if available.

Parameters:

attributes - the current exchange attributes

Returns:

the current observation context
