Method Detail

getClass

public static java.lang.Class getClass(java.lang.String className,
                                       boolean exitOnError,
                                       boolean logError)

createInstance

public static java.lang.Object createInstance(java.lang.String className,
                                              boolean exitOnError,
                                              boolean logError)

Use java to create a new instance of a class. Use exitOnError and logErr to define error handling. Default handling consumes the error ( ie...not finding and instantiating the class is not an error )

Parameters:

className - the full classname of the object to create

exitOnError - exit the program if error occurs

logError - log errors if one occurs

Returns:

new instance of the class, null if error

createInstance

public static java.lang.Object createInstance(java.lang.Class classToCreate,
                                              boolean exitOnError,
                                              boolean logError)

Use java to create a new instance of a class. Use exitOnError and logErr to define error handling. Default handling consumes the error ( ie...not finding and instantiating the class is not an error )

Parameters:

classToCreate - the class of the object to create

exitOnError - exit the program if error occurs

logError - log errors if one occurs

Returns:

new instance of the class, null if error

createAndCallMethod

public static java.lang.Object createAndCallMethod(java.lang.String className,
