Method Summary

static boolean	extractBoolean(org.w3c.dom.Node result) Extracts a Boolean from a result that consists of a Boolean only.
static int	extractInt(org.w3c.dom.Node doc) Extracts an Integer from a document that consists of an Integer only.
static java.lang.Long	extractLong(org.w3c.dom.Node doc) Extracts a Long from a document that consists of a Long only.
static java.lang.String	extractString(org.w3c.dom.Node d) Extracts a String from a Document consisting entirely of a String.
static org.w3c.dom.Document	parseCallResult(org.w3c.dom.Document doc) Used in the context of optimisation.
static org.w3c.dom.Document	parseCallResult(java.lang.Object rawResponse, javax.xml.parsers.DocumentBuilderFactory factory)
static java.lang.String	printDom(org.w3c.dom.Node n, java.lang.String prefix)
static void	printDom(org.w3c.dom.Node n, java.lang.String prefix, java.lang.StringBuilder sb) Prints out the DOM tree.
static void	stripEmptyTextNodes(org.w3c.dom.Node n) Hack...since DOM reads newlines as textnodes we want to strip out those nodes to make it easier to use the tree.

Method Detail

printDom

public static java.lang.String printDom(org.w3c.dom.Node n,
                                        java.lang.String prefix)

printDom

public static void printDom(org.w3c.dom.Node n,
                            java.lang.String prefix,
                            java.lang.StringBuilder sb)

Prints out the DOM tree.

Parameters:

n - the parent node to start printing from

prefix - string to append to output, should not be null

extractString

public static java.lang.String extractString(org.w3c.dom.Node d)

Extracts a String from a Document consisting entirely of a String.

Returns:

the String

extractInt

public static int extractInt(org.w3c.dom.Node doc)

Extracts an Integer from a document that consists of an Integer only.

Parameters:

doc -

Returns:

the Integer

extractLong

public static java.lang.Long extractLong(org.w3c.dom.Node doc)

Extracts a Long from a document that consists of a Long only.

Parameters:

doc -

Returns:

the Long

extractBoolean

public static boolean extractBoolean(org.w3c.dom.Node result)

Extracts a Boolean from a result that consists of a Boolean only.

Parameters:

result -

Returns:

the Boolean

parseCallResult

public static org.w3c.dom.Document parseCallResult(java.lang.Object rawResponse,
                                                   javax.xml.parsers.DocumentBuilderFactory factory)
                                            throws FacebookException

Throws:

FacebookException

stripEmptyTextNodes

public static void stripEmptyTextNodes(org.w3c.dom.Node n)

Hack...since DOM reads newlines as textnodes we want to strip out those nodes to make it easier to use the tree.

parseCallResult

public static org.w3c.dom.Document parseCallResult(org.w3c.dom.Document doc)
                                            throws FacebookException

Used in the context of optimisation. If we already have an XML snippet, it's not sensible to convert it to a string and then convert it back to a document.

Parameters:

doc -

Returns:

Throws:

FacebookException
