public static enum XPathEvaluationResult.XPathResultType extends Enum<XPathEvaluationResult.XPathResultType>
XPathResultType represents possible return types of an XPath evaluation. Provided as an enum type, it allows the use of switch statement. At the same time, a mapping is provided between the original QName types in XPathConstants
and class types used in the generic methods.

Method Detail
values
public static XPathEvaluationResult.XPathResultType[] values()
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
for (XPathEvaluationResult.XPathResultType c : XPathEvaluationResult.XPathResultType.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
valueOf
public static XPathEvaluationResult.XPathResultType valueOf(String name)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
- Parameters:
-
name
- the name of the enum constant to be returned. - Returns:
- the enum constant with the specified name
- Throws:
-
IllegalArgumentException
- if this enum type has no constant with the specified name -
NullPointerException
- if the argument is null
getQNameType
public static QName getQNameType(Class<?> clsType)
Returns the QName type as specified in XPathConstants
that corresponds to the specified class type.
- Parameters:
-
clsType
- a class type that the enum type supports - Returns:
- the QName type that matches with the specified class type, null if there is no match
