Encapsulates XPath values.

Objects of this class are usually created as the result of evaluating XPath expressions ( CXpathExpr ).

Every value object is assigned a certain type. Standard XPath type codes are specified using the anonymous enumeration in the declaration of this class.

CXpathValue

CXpathValue(Xpath::CValue *pValue);

Constructs the XPath value.

This constructor is intended mainly for the toolkit internal use.

Parameters:

pValue - the internal representation of the XPath value to be encapsulated in this object

~CXpathValue

~CXpathValue();

Destroys the XPath value.

GetType

int GetType();

Returns the type of this value.

Returns:

the type of this value

GetBoolean

bool GetBoolean();

Returns a boolean represented by this value.

It is an error if this value does not represent a boolean (that is, has the type other than CXpathValue::typeBoolean ).

Returns:

the boolean represented by this value

GetNumber

double GetNumber();

Returns a number represented by this value.

It is an error if this value does not represent a number (that is, has the type other than CXpathValue::typeNumber ).

Returns:

the number represented by this value

GetString

CString GetString();

Returns a string represented by this value.

It is an error if this value does not represent a string (that is, has the type other than CXpathValue::typeString ).

Returns:

the string represented by this value

GetValue

Xpath::CValue *GetValue();

Returns the internal representation of XPath value encapsulated in this object.

This method is intended mainly for the toolkit internal use.

Returns:

the internal representation of XPath value encapsulated in this object
