方法详细资料

getContext

java.lang.Object getContext()

返回:

The context object against which the XPath query was evaluated.

getXPathExpression

XPathExpression<T> getXPathExpression()

返回:

the XPathExpression instance that generated this diagnostic.

getResult

java.util.List<T> getResult()

Returns the results as they would be returned by the regular evaluate process (read-only).

返回:

the regular evaluated results.

getFilteredResults

java.util.List<java.lang.Object> getFilteredResults()

Returns the XPath results which are not returned by the regular evaluate process.

返回:

those results which were returned by the XPath query but were filtered out by the JDOM Filter.

getRawResults

java.util.List<java.lang.Object> getRawResults()

Returns the XPath results before any were filtered.

返回:

those results which were returned by the XPath query before any filtering.

isFirstOnly

boolean isFirstOnly()

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.

返回:

true if the evaluation was a first-only evaluation.
