Method Detail

addParameter

void addParameter(Parameter par)
                  throws M4Exception

Extends the array of ParameterObjects by the specified Parameter. Note, that the type of this Parameter has to be the same or a subclass of this ParameterArray's type! The Parameter will also have a reference to this object after it has been added by this method. After each invokation the array of ParameterObjects is invalidated and the active getter of this field will set it anew.

Parameters:

par - the Parameter to be added

Throws:

M4Exception

removeParameter

boolean removeParameter(Parameter par)
                        throws M4Exception

Inverts the addParameter(Parameter) functionality. The object specified is removed from the internal list of embedded Paramters. The reference of the Parameter to this object is also deleted.

Parameters:

par - the Parameter to be deleted

Returns:

true if the object could be deleted

Throws:

M4Exception

hasParameter

boolean hasParameter(Parameter par)
                     throws M4Exception

Parameters:

par - a Parameter

Returns:

true if a Parameter with the same ID is found in this ParameterArray

Throws:

M4Exception

getParameterType

short getParameterType()

Gets the parameterType.

Returns:

Returns a short

getParameterTypeS

java.lang.String getParameterTypeS()

Gets the parameterType as the String constant used in class DB.

Returns:

Returns a String

size

int size()

Returns:

the number of Parameters this ParameterArray contains.

getParameters

java.util.Collection getParameters()

Returns:

the Collection of embedded Parameter objects.

getParameterObjectArray

ParameterObject[] getParameterObjectArray()
                                          throws M4Exception

Active getter of the parameterObjectArray.

Returns:

Returns a ParameterObject[]

Throws:

M4Exception
