getParamsToValuesMap

public static <T> Map<ConfigurationParameterImpl,?> getParamsToValuesMap(T paramObject)

getParams

public static <T> ConfigurationParameterImpl[] getParams(Class<T> c)
                                                  throws IllegalAccessException

Throws:

IllegalAccessException

initParameterValues

public static <T> void initParameterValues(T configObj,
                                           org.apache.uima.UimaContext context)
                                    throws org.apache.uima.resource.ResourceInitializationException

Throws:

org.apache.uima.resource.ResourceInitializationException

getParameterValue

public static <T,V> V getParameterValue(T configObj,
                                        String paramName,
                                        org.apache.uima.UimaContext context)

Return the value set in the configuration for the parameter named. Gets the value from the UimaContext if provided. If configObj is a reader then gets the UimaContext from the getUimaContext method. If no context or the parameter is not set then a null value is returned.

Type Parameters:

T - Type of the configuration Object

V - Type of the value that is returned

Parameters:

configObj - object whose parameter value will be discovered

paramName - name of the parameter

context - UimaContext with the parameter values

Returns:

parameter value or null

getParameterTypeFromField

protected static void getParameterTypeFromField(Field field,
                                                org.apache.uima.resource.metadata.ConfigurationParameter param)

Get the multivalued and type parameter information from the field object. Collections are supported types for fields but only collections with a single generic type parameter that can return an array. If no type is matched then the type is set to ConfigurationParamter.TYPE_STRING.

Parameters:

field - field object from which class information can be retrieved.

param - ConfigurationParameter to store type and multi-value information.
