public interface Traceable
extends Locatable

A construct whose execution can be notified to a TraceListener. In practice this is either an expression, or a component such as a function or template or global variable.

Method Summary

Modifier and Type	Method	Description
default void	gatherProperties(java.util.function.BiConsumer<java.lang.String,java.lang.Object> consumer)	Get the properties of this object to be included in trace messages, by supplying the property values to a supplied consumer function
StructuredQName	getObjectName()	Get a name identifying the object of the expression, for example a function name, template name, variable name, key name, element name, etc.

Method Detail

getObjectName

StructuredQName getObjectName()

Get a name identifying the object of the expression, for example a function name, template name, variable name, key name, element name, etc. This is used only where the name is known statically.

Returns:

the QName of the object declared or manipulated by this instruction or expression

gatherProperties

default void gatherProperties(java.util.function.BiConsumer<java.lang.String,java.lang.Object> consumer)

Get the properties of this object to be included in trace messages, by supplying the property values to a supplied consumer function

Parameters:

consumer - the function to which the properties should be supplied, as (property name, value) pairs.
