Class XPathDiagnosticImpl<T>

java.lang.Object
org.jdom2.xpath.util.XPathDiagnosticImpl<T>
Type Parameters:
T - The generic type of the results from the XPathExpression
All Implemented Interfaces:
XPathDiagnostic<T>
public class XPathDiagnosticImpl<T> extends Object implements XPathDiagnostic<T>

    • XPathDiagnosticImpl

      public XPathDiagnosticImpl(Object dcontext, XPathExpression<T> dxpath, List<?> inraw, boolean dfirstonly)
      Create a useful Diagnostic instance for tracing XPath query results.
      Parameters:
      dcontext - The context against which the XPath query was run.
      dxpath - The XPathExpression instance which created this diagnostic.
      inraw - The data as returned from the XPath library.
      dfirstonly - If the XPath library was allowed to terminate after the first result.

  • Method Details

    • getContext

      public Object getContext()
      Specified by:
      getContext in interface XPathDiagnostic<T>
      Returns:
      The context object against which the XPath query was evaluated.

    • getXPathExpression

      public XPathExpression<T> getXPathExpression()
      Specified by:
      getXPathExpression in interface XPathDiagnostic<T>
      Returns:
      the XPathExpression instance that generated this diagnostic.

    • getResult

      public List<T> getResult()
      Description copied from interface: XPathDiagnostic
      Returns the results as they would be returned by the regular evaluate process (read-only).
      Specified by:
      getResult in interface XPathDiagnostic<T>
      Returns:
      the regular evaluated results.

    • getFilteredResults

      public List<Object> getFilteredResults()
      Description copied from interface: XPathDiagnostic
      Returns the XPath results which are not returned by the regular evaluate process.
      Specified by:
      getFilteredResults in interface XPathDiagnostic<T>
      Returns:
      those results which were returned by the XPath query but were filtered out by the JDOM Filter.

    • getRawResults

      public List<Object> getRawResults()
      Description copied from interface: XPathDiagnostic
      Returns the XPath results before any were filtered.
      Specified by:
      getRawResults in interface XPathDiagnostic<T>
      Returns:
      those results which were returned by the XPath query before any filtering.

    • isFirstOnly

      public boolean isFirstOnly()
      Description copied from interface: XPathDiagnostic
      Indicate whether the query was evaluated as a first-only evaluation. XPath libraries are allowed to stop processing the results after the first result is retrieved if first-only processing is set.
      Specified by:
      isFirstOnly in interface XPathDiagnostic<T>
      Returns:
      true if the evaluation was a first-only evaluation.

    • toString

      public String toString()
      Overrides:
      toString in class Object
