Class ContentHandlerProxyLocator

  • All Implemented Interfaces:

    public class ContentHandlerProxyLocator
    extends java.lang.Object
    implements org.xml.sax.Locator
    Implementation of the SAX Locator interface, used to supply location information to the ContentHandler.

    When the ContentHandler is used to receive the results of a query or stylesheet, the information supplied by the standard methods such as getSystemId() and getLineNumber() relates to the position of the expression/instruction in the stylesheet or query that caused the relevant nodes to be output.

    If the ContentHandler is used in other contexts, for example as the destination of an IdentityTransformer, the information reflects the position in the source document.

    If the output property saxon:supply-source-locator was set to the value "yes" (which in turn requires that tracing was enabled at compile time), the Locator will also contain information about the current location in the source document (specifically, the position of the context node). This will not always be 100% accurate, since there is some buffering of events in the output pipeline: it reflects the context node at the time the event reaches the ContentHandler, which may not be the same as the context node at the time the relevant instruction was executed; however, it still provides some information that may be useful for diagnostics.

        Get the System ID
        Specified by:
        getSystemId in interface org.xml.sax.Locator
        the system ID giving the location in the query or stylesheet of the most recent event notified
      • getLineNumber

        public int getLineNumber()
        Get the line number
        Specified by:
        getLineNumber in interface org.xml.sax.Locator
        the line number giving the location of the most recent event notified
      • getColumnNumber

        public int getColumnNumber()
        Get the column number
        Specified by:
        getColumnNumber in interface org.xml.sax.Locator

      • getContextItemStack

        public java.util.Stack getContextItemStack()
        Get the current item stack. This is a Stack, whose members are objects of class Item. The top item in the stack is the context node or atomic value; items further down the stack represent previous context node or atomic value
        the stack of context items
