public interface InstructionInfo
extends SourceLocator

Information about an instruction in the stylesheet or a construct in a Query, made available at run-time to a TraceListener

Method Summary

Methods

Modifier and Type	Method and Description
int	getConstructType() Get the type of construct.
int	getLineNumber() Get the line number of the instruction in the source stylesheet module.
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.
Iterator<String>	getProperties() Get an iterator over all the properties available.
Object	getProperty(String name) Get the value of a particular property of the instruction.
String	getSystemId() Get the system identifier (URI) of the source stylesheet or query module containing the instruction.

Method Detail

getConstructType

int getConstructType()

Get the type of construct. This will either be the fingerprint of a standard XSLT instruction name (values in StandardNames: all less than 1024) or it will be a constant in class Location.

Returns:

an integer identifying the kind of construct

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

getSystemId

String getSystemId()

Get the system identifier (URI) of the source stylesheet or query module containing the instruction. This will generally be an absolute URI. If the system identifier is not known, the method may return null. In some cases, for example where XML external entities are used, the correct system identifier is not always retained.

Specified by:

getSystemId in interface SourceLocator

Returns:

the URI of the containing module

getLineNumber

int getLineNumber()

Get the line number of the instruction in the source stylesheet module. If this is not known, or if the instruction is an artificial one that does not relate to anything in the source code, the value returned may be -1.

Specified by:

getLineNumber in interface SourceLocator

Returns:

the line number of the expression within the containing module

getProperty

Object getProperty(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

Iterator<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.
