Method Detail

splitClassNames

public static String[] splitClassNames(String blob)

Split concatenated class or method names string into an array of fully-qualified individual class and/or method names. This is used by the binding factory initialization, so that arrays of class and method names can be represented efficiently in the generated code. It takes as input a string consisting of compacted fully-qualified class names separated by '|' delimiter characters. If the compacted name starts with one or more '.' or '$' characters the corresponding number of package and class name levels are copied from the last name. Empty names are left null in the array.

Parameters:

blob - compacted class names separated by '|' delimiters

Returns:

expanded class names

expandNamespaces

public static String[] expandNamespaces(String blob,
                                        String[] uris)

Expand names URI indexes into an array of individual names URIs. This is used by the generated binding factory code, to reduce the size of the generated classes and methods. It takes as input a string where each character is a namespace index, biased by +2 in order to avoid the use of null characters, along with a table of corresponding namespace URIs. The character value 1 is used as a marker for the case where no namespace is associated with an index.

Parameters:

blob - string of characters representing namespace indexes

uris - namespace URIs defined in binding

Returns:

expanded class names

splitNames

public static String[] splitNames(String blob)

Split concatenated names string into an array of individual names. This is used by the binding factory initialization, so that arrays of name strings can be represented efficiently in the generated code. It takes as input a string consisting of names separated by '|' delimiter characters.

Parameters:

blob - element names separated by '|' delimiters

Returns:

expanded class names

splitInts

public static int[] splitInts(String blob)

Split concatenated ints string into an array of individual int values. This is used by the binding factory initialization, so that arrays of ints can be represented efficiently in the generated code.

Parameters:

blob -

Returns:

expanded index array

createReaderFactory

public static IXMLReaderFactory createReaderFactory(String cname)

Parser factory class loader method. This is used during initialization to check that a particular factory class is usable.

Parameters:

cname - class name

Returns:

reader factory instance

Throws:

RuntimeException - on error creating class instance

loadFactory

public static IXMLReaderFactory loadFactory()

Load the appropriate reader factory. This checks for a system property specifying the factory to be used, and if not found checks for an instance of one of the standard default factories.

Returns:

factory instance
