Method Detail

put

public void put(java.lang.String paramName,
                ParameterArray theParameter)
         throws M4Exception

Add a parameter to the dictionary. For loopsteps the method with additional loopNr parameter has to be used.

Specified by:

put in interface ParamDict

Parameters:

paramName - the name of the parameter as found in table OP_PARAM_T

theParameter - a ParameterArray object representing a parameter to be stored.

Throws:

M4Exception

put

public void put(java.lang.String paramName,
                int loopNr,
                ParameterArray theParameter)
         throws M4Exception

Specified by:

put in interface ParamDict

Throws:

M4Exception

See Also:

put(String, Object), just with the loop nr as an additional parameter

replace

public void replace(java.lang.String paramName,
                    int loopNr,
                    ParameterArray theParameter)
             throws M4Exception

replaces the parameter of referenced by a specific name for a specific loop nr

Specified by:

replace in interface ParamDict

Parameters:

paramName - the name of the key - the parameter name

loopNr - the loop nr

theParameter - the new parameter value

Throws:

M4Exception

containsKey

public boolean containsKey(java.lang.String paramName)

Checks whether for the given parameter name an entry is stored. This method is independent of loopstep or not, in both cases any occurence will be noticed.

Specified by:

containsKey in interface ParamDict

Parameters:

paramName - the name of the parameter

containsKey

public boolean containsKey(java.lang.String paramName,
                           int loopNr)

Checks whether for the given parameter name and a specific loop nr. a parameter is stored.

Specified by:

containsKey in interface ParamDict

containsParamArray

public boolean containsParamArray(ParameterArray paramArray)

Checks whether the given object exists as a value in the dictionary.

Specified by:

containsParamArray in interface ParamDict

Parameters:

paramArray - the object to check for

Returns:

true iff the object was found

removeParamArray

public boolean removeParamArray(ParameterArray paramArray)

If the given object exists as a value in the dictionary, then this method removes it.

Specified by:

removeParamArray in interface ParamDict

Parameters:

paramArray - the object to remove

Returns:

true iff the object could be removed

get

public ParameterArray get(java.lang.String paramName)
                   throws M4Exception

Specified by:

get in interface ParamDict

Parameters:

paramName - the name of the parameter to be looked up

Returns:

the parameter if stored, null otherwise. in case of loopsteps use the method get(String, int) instead.

Throws:

M4Exception

get

public ParameterArray get(java.lang.String paramName,
                          int loopNr)

Specified by:

get in interface ParamDict

Parameters:

paramName - the name of the parameter to be looked up

loopNr - the loop nr. for which to look up the parameter. Note that the first loopNr is "0", no matter if we have a looped parameter or not.

Returns:

the parameter if stored, null otherwise.

isLooped

public boolean isLooped(java.lang.String paramName)

Specified by:

isLooped in interface ParamDict

Parameters:

paramName - name of a parameter

Returns:

true iff the specified parameter is looped in the current step.
