Method Detail

putAnnotation

public static void putAnnotation(java.lang.String key,
                                 java.lang.String value)

Put an annotation to the current subsegment with a String value.

Parameters:

key - the key of the annotation

value - the value of the annotation

putAnnotation

public static void putAnnotation(java.lang.String key,
                                 java.lang.Number value)

Put an annotation to the current subsegment with a Number value.

Parameters:

key - the key of the annotation

value - the value of the annotation

putAnnotation

public static void putAnnotation(java.lang.String key,
                                 java.lang.Boolean value)

Put an annotation to the current subsegment with a Boolean value.

Parameters:

key - the key of the annotation

value - the value of the annotation

putMetadata

public static void putMetadata(java.lang.String key,
                               java.lang.Object value)

Put additional metadata for the current subsegment. The namespace used will be the namespace of the current subsegment if it is set else it will follow the namespace process as described in Tracing

Parameters:

key - the key of the metadata

value - the value of the metadata

putMetadata

public static void putMetadata(java.lang.String namespace,
                               java.lang.String key,
                               java.lang.Object value)

Put additional metadata for the current subsegment.

Parameters:

namespace - the namespace of the metadata

key - the key of the metadata

value - the value of the metadata

withEntitySubsegment

public static void withEntitySubsegment(java.lang.String name,
                                        com.amazonaws.xray.entities.Entity entity,
                                        java.util.function.Consumer<com.amazonaws.xray.entities.Subsegment> subsegment)

Adds a new subsegment around the passed consumer. This also provides access to the newly created subsegment. The namespace used follows the flow as described in Tracing This method is intended for use with multi-threaded programming where the context is lost between threads.

Parameters:

name - the name of the subsegment

entity - the current x-ray context

subsegment - the x-ray subsegment for the wrapped consumer

withEntitySubsegment

public static void withEntitySubsegment(java.lang.String namespace,

Adds a new subsegment around the passed consumer. This also provides access to the newly created subsegment. This method is intended for use with multi-threaded programming where the context is lost between threads.

Parameters:

namespace - the namespace of the subsegment

name - the name of the subsegment

entity - the current x-ray context

subsegment - the x-ray subsegment for the wrapped consumer

Adds a new subsegment around the passed consumer. This also provides access to the newly created subsegment. The namespace used follows the flow as described in Tracing

Parameters:

name - the name of the subsegment
