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>
A diagnostic implementation useful for diagnosing problems in XPath results.

This class tries to make all the data available as part of the internal structure which may assist people who are stepping-through the code from a debugging environment.

  • 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
