All Superinterfaces:

Location, org.xml.sax.Locator, javax.xml.transform.SourceLocator
```
public interface InstructionInfo
extends Location
```
Information about an instruction in the stylesheet or a construct in a Query, made available at run-time to a TraceListener. Although the class is mainly used to provide information for diagnostics, it also has a role in detecting circularities among global variables.

- 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
  - getProperty
```
java.lang.Object getProperty(java.lang.String name)
```
    Get the value of a particular property of the instruction. Properties of XSLT instructions are generally known by the name of the stylesheet attribute that defines them.
    
    Parameters:
    
    name - The name of the required property
    
    Returns:
    
    The value of the requested property, or null if the property is not available
  - getProperties
```
java.util.Iterator<java.lang.String> getProperties()
```
    Get an iterator over all the properties available. The values returned by the iterator will be of type String, and each string can be supplied as input to the getProperty() method to retrieve the value of the property. The iterator may return properties whose value is null.
    
    Returns:
    
    an iterator over the properties.
