public abstract class AccessLevelBeanInfo
extends java.beans.SimpleBeanInfo

This class is designed to implement access levels for bean properties. The system property "edu.uiowa.physics.das.beans.AccessLevelBeanInfo.AccessLevel" will determine the access level of the bean. The access levels that are currently supported are "ALL" and "END_USER". The access level must be set prior to this class being loaded.

Nested Class Summary

static class	AccessLevelBeanInfo.AccessLevel Type-safe enumeration class used to specify access levels for bean properties.
static class	AccessLevelBeanInfo.PersistenceLevel this level indicates what persistence is allowed.
protected static class	AccessLevelBeanInfo.Property AccessLevelBeanInfo.Property is a helper class for subclasses of AccessLevelBeanInfo to specify a list of properties in a way that is independant of the underlying Bean/PropertyDescriptor implementation.

Constructor Detail

AccessLevelBeanInfo

protected AccessLevelBeanInfo(AccessLevelBeanInfo.Property[] properties,
                              java.lang.Class beanClass)

Creates and instance of AccessLevelBeanInfo. Each element of the properties array must be of the type Object[] with the following format: { propertyName, accessorMethod, mutatorMethod, accessLevel} where the elements have the following meaning.

• propertyName - A String naming the property being specified.
• accessorMethod - A String specifying the name of the read method for this property.
• mutatorMethod - A String specifying the name of the write method for this property
• accessLevel - A org.das2.beans.AccessLevelBeanInfo.AccessLevel instance specifying the access level for this property.

Method Detail

getAccessLevel
