Method Detail

registerServiceListener

public void registerServiceListener()

Registers this configurator with the ServiceConfigManager to receive updates when the script configuration changes.

Throws:

IllegalStateException - if the configuration listener cannot be registered.

public void schemaChanged(String serviceName,
                          String version)

Specified by:

schemaChanged in interface ServiceListener

organizationConfigChanged

                                      String version,
                                      String orgName,
                                      String groupName,
                                      String serviceComponent,
                                      int type)

Specified by:

organizationConfigChanged in interface ServiceListener

globalConfigChanged

public void globalConfigChanged(String serviceName,
                                String version,
                                String groupName,
                                String serviceComponent,
                                int type)

Propagates script configuration changes to the configured StandardScriptEngineManager. Ignores all other changes.

Specified by:

globalConfigChanged in interface ServiceListener

updateConfig

protected void updateConfig(ScriptConstants.ScriptContext context)

Propagates script global configuration to the script engine manager.

Parameters:

context - The script context for which the config is updated.

compilePatternList

protected List<Pattern> compilePatternList(Set<String> patterns)

Compiles a set of class-name patterns into equivalent regular expressions. Each pattern consists of a series of name-parts separated by '.' characters. The only wild-card supported is '*' which is translated into a non-greedy match (.*?) in the regular expression. All other characters are escaped. The order of the resulting list is the iteration order of the set. There is no way to include a literal '*' character in the pattern, but '*' is not a valid character in a Java class name identifier.

Parameters:

patterns - the list of glob-style patterns to translate.

Returns:

the equivalent regular expression patterns.
