Method Details

addParameter

public void addParameter(Parameter p,
 boolean addSpaceSystem,
 boolean addParameterType)
                  throws IOException

Throws:

IOException

addParameters

public void addParameters(List<Parameter> parameters,
 boolean createSpaceSystems,
 boolean createParameterTypes)
                   throws IOException

Adds parameters to the MDB after which it persist the corresponding subtree to the file

If any of spacesystems of the parameters are not writable, an IllegalArgumentException will be thrown and no parameter will be added

Throws:

IOException

addParameterType

public void addParameterType(ParameterType ptype,
 boolean createSpaceSystem)
                      throws IOException

Throws:

IOException

addParameterTypes

public void addParameterTypes(List<ParameterType> ptypeList,
 boolean createSpaceSystem)
                       throws IOException

Throws:

IOException

createSystemParameter

public SystemParameter createSystemParameter(String parameterQualifiedNamed,
 ParameterType ptype,
 String shortDescription)

Creates and returns a system parameter with the given qualified name. If the parameter already exists it is returned.

Parameters:

parameterQualifiedNamed - - the name of the parmaeter to be created. It must start with XtceDb.YAMCS_SPACESYSTEM_NAME

ptype -

Returns:

the parameter created or already existing.

Throws:

IllegalArgumentException - if the parameterQualifiedNamed does not start with XtceDb.YAMCS_SPACESYSTEM_NAME

addSystemParameterType

public ParameterType addSystemParameterType(ParameterType ptype)

Adds a parameter type to the MDB. The type has to have the qualified name set and start with XtceDb.YAMCS_SPACESYSTEM_NAME.

If a type with the same name already exists, it is returned instead. No check is performed that the existing type and the new type are the same or even compatible.

Parameters:

ptype -

Returns:

getOrCreateBasicParameterType

public ParameterType getOrCreateBasicParameterType(String namespace,
 Yamcs.Value.Type type,
 UnitType unit)
                                            throws IOException

Creates if it does not exist and returns a basic parameter type corresponding to the value.

The namespace has to be writable otherwise an IllegalArgumentException will be thrown

Throws:

IOException

getOrCreateBasicArgumentType

public ArgumentType getOrCreateBasicArgumentType(String namespace,
 Yamcs.Value.Type type,
 UnitType unit)
                                          throws IOException

Creates if it does not exist and returns a basic argument type corresponding to the value.

The namespace has to be writable otherwise an IllegalArgumentException will be thrown

Throws:

IOException
