      Specified by:
      getSystemId in interface SourceLocator
      Returns:
      the module's URI

    • setLineNumber

      public void setLineNumber(int lineNumber)

      Parameters:
      lineNumber - the line number

    • getLineNumber

      public int getLineNumber()
      Get the line number of the instruction within its module
      Specified by:
      getLineNumber in interface InstructionInfo
      Specified by:
      getLineNumber in interface Locator
      Specified by:
      getLineNumber in interface SourceLocator

    • setObjectNameCode

      public void setObjectNameCode(int nameCode)
      Set 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.

    • getObjectNameCode

      public int getObjectNameCode()
      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.
      Specified by:
      getObjectNameCode in interface InstructionInfo

    • setProperty

      public void setProperty(String name, Object value)
      Set a named property of the instruction

    • getProperty

      public Object getProperty(String name)
      Get a named property of the instruction
      Specified by:
      getProperty in interface InstructionInfo
      Parameters:

      Returns:
      The value of the requested property, or null if the property is not available

    • getProperties

      public Iterator 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.
      Specified by:
      getProperties in interface InstructionInfo

    • getPublicId

      public String getPublicId()
      Get the public ID of the module containing the instruction. This method is provided to satisfy the SourceLocator interface. However, the public ID is not maintained by Saxon, and the method always returns null
      Specified by:
      getPublicId in interface Locator
      Specified by:
      getPublicId in interface SourceLocator
      Returns:
      null

      Get the column number identifying the position of the instruction.
      Specified by:
      getColumnNumber in interface Locator
      Specified by:
      getColumnNumber in interface SourceLocator
      Returns:
      -1 if column number is not known

    • getInstructionInfo

      public InstructionInfo getInstructionInfo()
      Get the InstructionInfo details about the construct. This is to satisfy the InstructionInfoProvider interface.
