EntityDefinition

public EntityDefinition(ClassInfo introspectionInfo,

                 throws WTIntrospectionException

Builds an Entity definition using introspection

addSubTypes

                         Schema parentSchema)
                  throws WTIntrospectionException

Throws:

WTIntrospectionException

addAttributes

private void addAttributes(ClassInfo introspectionInfo,
                           Schema parentSchema)
                    throws WTIntrospectionException

Throws:

WTIntrospectionException

isNativeType

private boolean isNativeType(Class typeClass)

isPublicDeclaredProperty

private boolean isPublicDeclaredProperty(PropertyDescriptor property)

getExpressNameForField

private String getExpressNameForField(String fieldName)

getExpressNameForType

private String getExpressNameForType(Class type)

getExpressNameFor

private String getExpressNameFor(ClassInfo introspectionInfo)

getName

String getName()

addSubtype

void addSubtype(String subtypeName)

addAttribute

void addAttribute(String name,
                  String type)

removeAttributeNameClashes

void removeAttributeNameClashes(Schema schema)

Many attributes are repeated in subclasses. This is not valid in Express so this method checks all attributes and flags those as inherited. Inherited attributes are then commented out in the generated Express. It also possible for the same attribute name to appear twice, in which case an incremental number is appended to its name.

markInheritedAttributes

void markInheritedAttributes(Schema schema)

collectSubAttributes

private void collectSubAttributes(Hashtable attributesHolder,
                                  Schema schema)

Collect all the attributes for this Entity and any of its sub-Entities

collectAttributes

void collectAttributes(Hashtable attributesHolder,
                       Schema schema)

Collect all the attributes for this Entity and any of its sub-Entities

getSubTypes

protected Vector getSubTypes()

getAttributes

protected Vector getAttributes()

writeExpress

public void writeExpress(PrintStream outStream)

Write this Entity in Express to the given print stream.
