getPropertyMapFromClass

public java.util.Map getPropertyMapFromClass(java.lang.Class type,
                                             boolean readRequired,
                                             boolean writeRequired)
                                      throws MarshallException

Description copied from interface: NamedConverter

Get a map of property names to implementations of Property.

HibernateBeanConverter (and maybe others) may want to provide alternate versions of bean.getClass(), and we may wish to fake or hide properties in some cases.

If you have a real object to investigate then it is probably better to call NamedConverter.getPropertyMapFromObject(Object, boolean, boolean) because that version can take into accound extra runtime type info.

Specified by:

getPropertyMapFromClass in interface NamedConverter

Overrides:

getPropertyMapFromClass in class BeanConverter

Parameters:

type - The class to find bean info from

readRequired - The properties returned must be readable

writeRequired - The properties returned must be writeable

Returns:

An array of PropertyDescriptors describing the beans properties

Throws:

MarshallException - If the introspection fails

NamedConverter.getPropertyMapFromObject(Object, boolean, boolean)

fixMissingThrowableProperty

protected void fixMissingThrowableProperty(java.util.Map descriptors,
                                           java.lang.String name,
                                           java.lang.String readMethodName)
                                    throws java.beans.IntrospectionException

Make sure Throwable's standard properties are added (fix for Bean Introspector peculiarities)

Parameters:

descriptors - The Map of the known descriptors

name - The name of the property to add

readMethodName - A method name to use when getting said property

Throws:

java.beans.IntrospectionException - If we fail to build a PropertyDescriptor
