Class AttributeLocation

  • All Implemented Interfaces:
    javax.xml.transform.SourceLocator, Location, org.xml.sax.Locator

    public class AttributeLocation
    extends java.lang.Object
    implements Location
    A Location corresponding to an attribute in a document (often a stylesheet)
    • Method Detail

      • setElementNode

        public void setElementNode​(NodeInfo node)
        Add a reference to the containing element node. This needs care because we don't want to retain links to the source stylesheet at run-time; it is therefore done only for static errors
      • getElementNode

        public NodeInfo getElementNode()
        Get the reference to the containing element node, if available.
        the containing element node, or null if not available or not applicable.
      • getElementName

        public StructuredQName getElementName()
        Get the name of the containing element
        the name of the containing element in the stylesheet
      • getAttributeName

        public StructuredQName getAttributeName()
        Get the name of the containing attribute
        the name of the containing attribute in the stylesheet. May be null if the XPath expression is contained in a text node
      • getColumnNumber

        public int getColumnNumber()
        Get the column number. This column number is relative to the line identified by the line number. Column numbers start at 1.
        Specified by:
        getColumnNumber in interface Location
        Specified by:
        getColumnNumber in interface org.xml.sax.Locator
        Specified by:
        getColumnNumber in interface javax.xml.transform.SourceLocator
        the column number, or -1 if the information is not available.
      • getSystemId

        public java.lang.String getSystemId()
        Get the system ID. This should be the system identifier of an XML external entity; if a stylesheet module comprises multiple external entities, the distinction should be retained. This means, for example, that an instruction in a stylesheet can have a different system identifier from its parent instruction. However, SAX parsers only provide location information at the element level, so when part of an XPath expression is in a different external entity from other parts of the same expression, this distinction is lost.

        The system identifier of a node is in general not the same as its base URI. The base URI is affected by xml:base attributes; the system identifier is not.

        Specified by:
        getSystemId in interface Location
        Specified by:
        getSystemId in interface org.xml.sax.Locator
        Specified by:
        getSystemId in interface javax.xml.transform.SourceLocator
        the system ID, or null if the information is not available.
      • getPublicId

        public java.lang.String getPublicId()
        Get the Public ID
        Specified by:
        getPublicId in interface Location
        Specified by:
        getPublicId in interface org.xml.sax.Locator
        Specified by:
        getPublicId in interface javax.xml.transform.SourceLocator
        usually null
      • getLineNumber

        public int getLineNumber()
        Get the line number. This line number is relative to the external entity identified by the system identifier. Line numbers start at 1. The value may be an approximation; SAX parsers only provide line number information at the level of element nodes.
        Specified by:
        getLineNumber in interface Location
        Specified by:
        getLineNumber in interface org.xml.sax.Locator
        Specified by:
        getLineNumber in interface javax.xml.transform.SourceLocator
        the line number, or -1 if the information is not available.
      • saveLocation

        public Location saveLocation()
        Get an immutable copy of this Location object. By default Location objects may be mutable, so they should not be saved for later use. The result of this operation holds the same location information, but in an immutable form.
        Specified by:
        saveLocation in interface Location
        an immutable copy (which may be the original object, if it is already immutable)
