Constructor Details

MergerExtensionRegistryListener

public MergerExtensionRegistryListener(String pluginID,
 String extensionPointID,
 org.eclipse.core.runtime.ILog log,
 IMerger.Registry mergerRegistry)

Constructor.

Parameters:

pluginID - The plugin id.

extensionPointID - The extension point id.

log - The log in which to report failures.

mergerRegistry - The actual registry that will be populated by this listener.

Method Details

readElement

protected boolean readElement(org.eclipse.core.runtime.IConfigurationElement element,
 AbstractRegistryEventListener.Action b)

Reads the given element. This method can be call when the element is added or remove. The action reflect it. It returns true if the element is recognized as valid regarding the monitored extension point. It will be call on sub elements recursively for all recognized ones.

Overrides:

readElement in class AbstractRegistryEventListener

Parameters:

element - the element to be read.

b - is the element added or removed.

Returns:

true if the element is recognized as valid regarding the monitored extension point.

validateExtensionElement

protected boolean validateExtensionElement(org.eclipse.core.runtime.IConfigurationElement element)

Validates if the given element is an element for the given extension and is well constructed. Returns true if the element should be further parsed for addition or removal.

Specified by:

validateExtensionElement in class AbstractRegistryEventListener

Parameters:

element - the element to validate.

Returns:

true if the element should be further parsed for addition or removal, else otherwise.

See Also:

• AbstractRegistryEventListener.validateExtensionElement(org.eclipse.core.runtime.IConfigurationElement)

addedValid

protected boolean addedValid(org.eclipse.core.runtime.IConfigurationElement element)

Process the given element as the addition of a valid element extension.

Specified by:

addedValid in class AbstractRegistryEventListener

Parameters:

element - the element to be added.

Returns:

true if the given element has been added and if its children should be processed, false otherwise.

See Also:

• AbstractRegistryEventListener.addedValid(org.eclipse.core.runtime.IConfigurationElement)

removedValid

protected boolean removedValid(org.eclipse.core.runtime.IConfigurationElement element)

Process the given element as the removal of a valid element extension.

Specified by:

removedValid in class AbstractRegistryEventListener

Parameters:

element - the element to be removed.

Returns:

true if the given element has been removed and if its children should be processed, false otherwise.
