Detailed Description

Templated parameter list.

Parameters can be added and retreived with the templated "get" and "set" functions. These parameters can any data type which uses value sementics (e.g. double, float, int, *double, *float, *int, ...) which includes other parameter lists, allowing for a hierarchy of parameter lists. These parameters can also be pointers to vectors or functions.

Examples:

FancyOutputting_test.cpp, and ParameterList/cxx_main.cpp.

EValidateUsed const   validateUsed = VALIDATE_USED_ENABLED,
EValidateDefaults const   validateDefaults = VALIDATE_DEFAULTS_ENABLED
)  const
 

Validate the parameters in this list given valid selections in the input list.

Parameters:
validParamList [in] This is the list that the parameters and sublist in *this are compared against.
depth [in] Determines the number of levels of depth that the validation will recurse into. A value of dpeth=0 means that only the top level parameters and sublists will be checked. Default: depth = large number.
validateUsed [in] Determines if parameters that have been used are checked against those in validParamList. Default: validateDefaults = VALIDATE_DEFAULTS_ENABLED.
validateDefaults [in] Determines if parameters set at their default values using get(name,defaultVal) are checked against those in validParamList. Default: validateDefaults = VALIDATE_DEFAULTS_ENABLED.
If a parameter in *this is not found in validParamList then an std::exception of type Exceptions::InvalidParameterName will be thrown which will contain an excellent error message returned by excpt.what(). If the parameter exists but has the wrong type, then an std::exception type Exceptions::InvalidParameterType will be thrown. If the parameter exists and has the right type, but the value is not valid then an std::exception type Exceptions::InvalidParameterValue will be thrown.

Recursive validation stops when:

  • The maxinum depth is reached

  • A sublist note in validParamList has been marked with the disableRecursiveValidation() function, or

  • There are not more parameters or sublists left in *this

A breath-first search is performed to validate all of the parameters in one sublist before moving into nested subslist.

void Teuchos::ParameterList::validateParametersAndSetDefaults (  ParameterList const &  validParamList,
int const   depth = 1000
) 
 

Validate the parameters in this list given valid selections in the input list and set defaults for those not set.

Parameters:
validParamList [in] This is the list that the parameters and sublist in *this are compared against.
depth [in] Determines the number of levels of depth that the validation will recurse into. A value of dpeth=0 means that only the top level parameters and sublists will be checked. Default: depth = large number.
If a parameter in *this is not found in validParamList then an std::exception of type Exceptions::InvalidParameterName will be thrown which will contain an excellent error message returned by excpt.what(). If the parameter exists but has the wrong type, then an std::exception type Exceptions::InvalidParameterType will be thrown. If the parameter exists and has the right type, but the value is not valid then an std::exception type Exceptions::InvalidParameterValue will be thrown. If a parameter in validParamList does not exist in *this, then it will be set at its default value as determined by validParamList.

Recursive validation stops when:

  • The maxinum depth is reached

  • A sublist note in validParamList has been marked with the disableRecursiveValidation() function, or

  • There are not more parameters or sublists left in *this

A breath-first search is performed to validate all of the parameters in one sublist before moving into nested subslist.

void setStringParameterFromArray (  const std::string &  paramName,
const Array< T > &  array,
ParameterList *  paramList
)  [related]
 

Set a std::string parameter representation of an array.

Parameters:
paramName [in] The name of the parameter containing the std::string representation of the array.
array [in] The array that will be set as a std::string parameter.
paramList [in/out] The parameter list that the array will be set on.

Array< T > getArrayFromStringParameter (  const ParameterList &  paramList,
const std::string &  paramName,
const int  arrayDim = -1,
const bool  mustExist = true
)  [related]
 

Get an Array object (with entries of type T) from a parameter holding a std::string representation of the array.

Parameters:
paramList [in] The parameter list to extract the parameter array from.
paramName [in] The name of the parameter containing the std::string representation of the array.
arrayDim [in] If arrayDim >= 0, then the read in array must be equal to this dimension, or an std::exception will be thrown. If arrayDim < 0, then an array of any dimension will be returned. The default is -1 and therefore no array length validation will be performed.
mustExist [in] If mustExist==true, then the parameter paramName must exist and must contain a valid array, or an std::exception is thrown. If mustExist==false, and if the parameter paramName does not exist or contains an empty array std::string value, then an empty array object will be returned.
Returns:
an array object if an std::exception is not thrown. If mustExist==false and the parameter does not exist, then an empty array object will be returned. If mustExist==true and arrayDim < 0, then if the parameter paramName exists and its array value is valid, then the converted array, of any size, will be returned. If mustExist==true and arrayDim >= 0 then an array of dimension arrayDim will be returned if an std::exception is not thrown.
Exceptions:

Detailed Description:

This function allows Array<T> objects to be read in from a parameter with a std::string representation of the array. The templated function Teuchos::fromStringToArray() (see documentation for Teuchos::Array) is used to parse the std::string representation and return the array object (see this function's documentation for details on what the formatting of the array std::string must be and what can be handled and what can not be handled.
