Method Detail

getType

public static Class<? extends XAttribute> getType(XAttribute attribute)

For the given attribute, returns its type, i.e., the most high-level, typed interface this attribute implements.

Parameters:

attribute - Attribute to analyze.

Returns:

High-level type interface of this attribute.

getTypeString

public static String getTypeString(XAttribute attribute)

For the given attribute, derives the standardized string describing the attributes specific type (used, e.g., for serialization).

Parameters:

attribute - Attribute to extract type string from.

Returns:

String representation of the attribute's specific type.

derivePrototype

public static XAttribute derivePrototype(XAttribute instance)

Derives a prototype for the given attribute. This prototype attribute will be equal in all respects, expect for the value of the attribute. This value will be set to a default value, depending on the specific type of the given attribute.

Parameters:

instance - Attribute to derive prototype from.

Returns:

The derived prototype attribute.

composeAttribute

public static XAttribute composeAttribute(XFactory factory,
                                          String key,
                                          String value,
                                          String type,
                                          XExtension extension)

Composes the appropriate attribute type from the string-based information found, e.g., in XML serializations.

Parameters:

factory - Factory to use for creating the attribute.

key - Key of the attribute.

value - Value of the attribute.

type - Type string of the attribute.

extension - Extension of the attribute (can be null).

Returns:

An appropriate attribute.

extractExtensions

public static Set<XExtension> extractExtensions(Map<String,XAttribute> attributeMap)

Static helper method for extracting all extensions from an attribute map.

Parameters:

attributeMap - The attribute map from which to extract extensions.

Returns:

The set of extensions in the attribute map.
