Method Detail

resetEventDidOccur

public void resetEventDidOccur()

Specified by:

resetEventDidOccur in interface ResetEventListener

getComponentProperty

public java.lang.String getComponentProperty(IComponent component,
                                    java.lang.String propertyName)

Description copied from interface: ComponentPropertySource

Returns the property value for a particular named meta-data property of the component. The search order is:

• The component's specification
• The specification of the application (or the library containing the component).
• The chain of global property sources.

Specified by:

getComponentProperty in interface ComponentPropertySource

Returns:

the value of the given key, or null if not found.

getLocalizedComponentProperty

public java.lang.String getLocalizedComponentProperty(IComponent component,
                                             java.util.Locale locale,
                                             java.lang.String propertyName)

Description copied from interface: ComponentPropertySource

Like ComponentPropertySource.getComponentProperty(IComponent, String), but the property name will be localized to the component's current locale (determined from its page). Localizing the property name means that a suffix may be appended to it. If the fully localized name is not found, then the locale is generalized (i.e., from "en_UK" to "en" to nothing) until a match is found.

Specified by:

getLocalizedComponentProperty in interface ComponentPropertySource

Returns:

the value of the given property name, or null if not found.

getNamespaceProperty

public java.lang.String getNamespaceProperty(INamespace namespace,
                                    java.lang.String propertyName)

Description copied from interface: ComponentPropertySource

Returns the property value for a particular named meta-data property of the namespace. The search order is:

• The library or application specification for the namespace.
• The chain of global property sources.

Specified by:

getNamespaceProperty in interface ComponentPropertySource

Returns:

the value of the given key, or null if not found.

getLocalizedNamespaceProperty

public java.lang.String getLocalizedNamespaceProperty(INamespace namespace,
                                             java.util.Locale locale,
                                             java.lang.String propertyName)

Description copied from interface: ComponentPropertySource

As with ComponentPropertySource.getLocalizedComponentProperty(IComponent, Locale, String), but with a INamespace.

Specified by:

getLocalizedNamespaceProperty in interface ComponentPropertySource

setChainBuilder

public void setChainBuilder(org.apache.hivemind.lib.chain.ChainBuilder chainBuilder)

setGlobalProperties

public void setGlobalProperties(IPropertySource globalProperties)
