Method Detail

prepareAttributeMetadata

public static Map<String,Object> prepareAttributeMetadata(SAXDocumentElement el)

Prepare metadata of attribute tag stored in the parameter. If the parameter has a defined attribute use, add this information to metadata.

Parameters:

el - Instance of the wrapper class containing the attribute tag, from which the metadata is extracted.

Returns:

New metadata.

isContainer

public static boolean isContainer(Element elem)

Finds out if parameter is only a temporary container with the name set by CONTAINER_NAME constant.

Parameters:

elem - Instance to be examined.

Returns:

True if elem is a container, false otherwise.

prepareElementName

public static String prepareElementName(SAXDocumentElement el,
                                        boolean isContainer)

Prepares the name for a rule by extracting data from el . Resulting name is taken from attributes of the tag. Attribute name has priority before attribute ref. If it is a container, special internal value for the name is used.

Parameters:

el - Instance wrapping the tag.

isContainer - Indicates if the name is prepared only for a container.

Returns:

New name for the rule.

prepareElementMetadata

public static Map<String,Object> prepareElementMetadata(SAXDocumentElement el,
                                                        boolean isContainer)

Prepares the metadata for a rule by extracting information from el. If it is not a container, IGGUtils.ATTR_FROM_SCHEMA is added to metadata. If el has ref attribute specified, IGGUtils.METADATA_SENTINEL is added to metadata.

Parameters:

el - Instance wrapping the tag.

isContainer - Indicates if the metadata is prepared only for a container.

Returns:

New metadata.

finalizeElement

public static void finalizeElement(Element elem)

Finalizes the element, makes it immutable. Should be called only when all type dependencies have been resolved.

Parameters:

elem - Element to finalize.
