Method Detail

booleanValue

public abstract boolean booleanValue()
Returns the result as a boolean value. Returns the value of a boolean result, true for a non-empty string result, true for a non-zero number result, and true from a non-empty node-set.

Returns: The result as a boolean value

equals

public abstract boolean equals(XPathResult result)
Returns true if the given expression is the same tyoe as this result and has the same value as this result.

Parameters: result An XPath result

Returns: True if same type and same value as this result

getResultType

public abstract int getResultType()
Returns the type of this result.

Returns: The type of this result

javaObject

public abstract Object javaObject()
Returns the result as a Java object. Returns an object of type java.lang.Boolean for a boolean result, an object of type java.lang.String for a string result, an object of type java.lang.Double for a number result, or an object of type NodeSet for a node-set.

Returns: The result as a Java object

numberValue

public abstract double numberValue()
Returns the result as a number value. Returns 0 or 1 for a boolean result, the parsed value for a string result, the value of a number result, or the parsed value of a node-set.

Returns: The result as a number value

stringValue

public abstract String stringValue()
Returns the result as a string value. Returns "false" or "true" for a boolean result, the value of a string result, the string value of a number result, or the string value of a node-set.

Returns: The result as a string value
