Enum XPathEvaluationResult.XPathResultType

java.lang.Object
- java.lang.Enum<XPathEvaluationResult.XPathResultType>
- - javax.xml.xpath.XPathEvaluationResult.XPathResultType

All Implemented Interfaces:: Serializable, Comparable<XPathEvaluationResult.XPathResultType>

Enclosing interface:: XPathEvaluationResult<T>

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.

Enum Constant Detail

ANY

public static final XPathEvaluationResult.XPathResultType ANY

Any type that represents any of the 5 other types listed below. Maps to XPathEvaluationResult.

BOOLEAN

public static final XPathEvaluationResult.XPathResultType BOOLEAN

The XPath 1.0 boolean data type. Maps to Java Boolean.

NUMBER

public static final XPathEvaluationResult.XPathResultType NUMBER

The XPath 1.0 Number data type. Maps to Java Number. Of the subtypes of Number, only Double, Integer and Long are required.

STRING

public static final XPathEvaluationResult.XPathResultType STRING

The XPath 1.0 String data type. Maps to Java String.

NODESET

public static final XPathEvaluationResult.XPathResultType NODESET

The XPath 1.0 NodeSet data type. Maps to NodeList.

NODE

public static final XPathEvaluationResult.XPathResultType NODE

The XPath 1.0 NodeSet data type. Maps to Node.

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
