Method Detail

getAttributes

public static List<String> getAttributes(String extensionPointID,
                                         String elementName,
                                         String attributeName)

Gets all attributes registered at a given extension point at a given element and conforming to a given attribute.

Parameters:

extensionPointID - the extension point identifier; pointing to the extension point to get attributes from.

elementName - the name of the configuration element.

attributeName - the name of the attribute.

Returns:

a list of attributes conforming to the given parameters.

getExecutableExtensions

public static <DATA_TYPE> List<DATA_TYPE> getExecutableExtensions(String extensionPointID,
                                                                  String attributeName)

Gets all executable extensions registered at a given extension point conforming to a given attribute.

Type Parameters:

DATA_TYPE - the data type of the executable extension.

Parameters:

extensionPointID - the extension point identifier; pointing to the extension point to get executable extensions from.

attributeName - the name of the attribute.

Returns:

list of executable extension for the given attribute.

getExecutableExtension

public static <DATA_TYPE> DATA_TYPE getExecutableExtension(String extensionPointID,
                                                           String attributeName,
                                                           String filterAttributeName,
                                                           String filterAttributeValue)

Gets all executable extensions registered at a given extension point conforming to a given attribute and filtered by the given attribute and its value.

Type Parameters:

DATA_TYPE - the data type of the executable extension.

Parameters:

extensionPointID - the extension point identifier; pointing to the extension point to get executable extensions from.

attributeName - the name of the attribute.

filterAttributeName - the attribute to be used for filtering.

filterAttributeValue - the atrribute's value to be used for filtering. Found attributes have to equal this value in case they should be chosen.

Returns:

list of executable extension for the given attribute.

getExecutableExtensions
