All Implemented Interfaces:

org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.BeanNameAware, org.springframework.beans.factory.config.BeanFactoryPostProcessor, org.springframework.core.Ordered, org.springframework.core.PriorityOrdered

public class PreferenceContext
extends org.springframework.beans.factory.config.PropertyPlaceholderConfigurer

Central configuration for OMERO properties from (in order):

• Any injected Properties instances
• Java System.getProperties()
• Any configured property files

As of OMERO 4.2, server configurations are not stored in Java's Preferences API but in an IceGrid xml file under etc/grid of the server installation. The properties are set in the config file on node startup, for example in var/master/servers/Blitz-0/config/config. When the Java process starts, ome.services.blitz.Entry places the values in {#link System.getProperties().

Since:

3.0-Beta3

Constructor Detail

PreferenceContext

public PreferenceContext()

By default, configures this instance for PropertyPlaceholderConfigurer.SYSTEM_PROPERTIES_MODE_OVERRIDE as well as ignoring unfound resources.

Method Detail

postProcessBeanFactory

public void postProcessBeanFactory(org.springframework.beans.factory.config.ConfigurableListableBeanFactory bf)

Specified by:

postProcessBeanFactory in interface org.springframework.beans.factory.config.BeanFactoryPostProcessor

Overrides:

postProcessBeanFactory in class org.springframework.beans.factory.config.PropertyResourceConfigurer

getProperty

public java.lang.String getProperty(java.lang.String key)

Lookup method for getting access to the merged properties for this instance.

setProperty

public void setProperty(java.lang.String key,
                        java.lang.String value)

With ticket:2214, preferences are no longer mutable. For that, we will need a python server which can update the XML file.

setPreferences

public void setPreferences(java.util.List<Preference> preferences)

resolveAlias

public java.lang.String resolveAlias(java.lang.String key)

getKeySet

public java.util.Set<java.lang.String> getKeySet()

checkDatabase

public boolean checkDatabase(java.lang.String key)

canRead

public boolean canRead(EventContext ec,
                       java.lang.String key)
