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.

    Modifier and Type
    Method
    Description
    default void
    gatherProperties(BiConsumer<String,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 Details

    • 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(BiConsumer<String,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.
