Method Details

loadDescriptor

public static org.jdom.Document loadDescriptor(String fileName)
                                        throws org.jdom.JDOMException,
IOException

Loads in a descriptor file and returns the resulting Document. This will set the schema explicitly to the one found in the current package called SCHEMA_FILE_NAME, so the file need not have the schema specified.

Parameters:

fileName - the name of the descriptor file

Returns:

a Document object corresponding to the specified descriptor file

Throws:

org.jdom.JDOMException - if there was an error inside JDOM

IOException - if there was an error reading

RunTimeException - if the file cannot be found

findBestValue

public static String findBestValue(Queryable queryable,
 org.jdom.Element nodeToHandle,
 String attributeName,
 boolean useXPath)

Tries to retrieve an attribute from the nodeToHandle based on the target. If useXPath is true it then will query the Queryable using it's selectNode function and return the result of the Queryable's getValue on that result (or null if the result is null). If useXPath is false it will skip the XPath/Queryable steps and just return the toString of the attribute's value.

Parameters:

queryable - the queryable source for fetching values from

element - the element to fetch the target from

attributeName - the attribute's name.

Returns:

a value as speciied

findExplicitTargetParent

public static Object findExplicitTargetParent(Queryable queryable,
 String targetPath)

Parameters:

queryable - the queryable source for fetching values from

targetPath -

Returns:

a value as speciied

getName

public static String getName(String targetPath)

Parameters:

targetPath -

Returns:

a value as speciied

isGarbage

public static boolean isGarbage(String string)

Checks if a string is null or "".

Parameters:

string - a string to check

Returns:

true if the string is either null or equal to ""

findBestValue

public static String findBestValue(Queryable queryable,
 org.jdom.Element element,
 String attributeName)

Same as findBestValue(queryable, element, attributeName, true)

main

public static void main(String[] args)
