◆ getSubKeys()
const ParameterTree::KeyVector & ParameterTree::getSubKeys | ( | ) | const |
get substructure keys
Returns a vector of all keys associated to (key,substructure) entries in order of appearance
- Returns
- reference to entry vector
◆ getValueKeys()
const ParameterTree::KeyVector & ParameterTree::getValueKeys | ( | ) | const |
get value keys
Returns a vector of all keys associated to (key,values) entries in order of appearance
- Returns
- reference to entry vector
◆ hasKey()
bool ParameterTree::hasKey | ( | const std::string & | key | ) | const |
test for key
Tests whether given key exists.
- Parameters
-
key key name
- Returns
- true if key exists in structure, otherwise false

◆ hasSub()
bool ParameterTree::hasSub | ( | const std::string & | sub | ) | const |
test for substructure
Tests whether given substructure exists.
- Parameters
-
sub substructure name
- Returns
- true if substructure exists in structure, otherwise false

◆ operator[]() [1/2]
std::string & ParameterTree::operator[] | ( | const std::string & | key | ) |
get value reference for key
Returns reference to value for given key name. This creates the key, if not existent.
- Parameters
-
key key name

◆ operator[]() [2/2]
const std::string & ParameterTree::operator[] | ( | const std::string & | key | ) | const |
get value reference for key
Returns reference to value for given key name. This creates the key, if not existent.
- Parameters
-
key key name
- Returns
- reference to corresponding value
- Exceptions
-
Dune::RangeError if key is not found

void ParameterTree::report | ( | std::ostream & | stream = std::cout , |
const std::string & | prefix = "" |
||
) | const |
◆ sub() [1/2]
ParameterTree & ParameterTree::sub | ( | const std::string & | sub | ) |
get substructure by name
- Parameters
-
sub substructure name
- Returns
- reference to substructure

◆ sub() [2/2]
const ParameterTree & ParameterTree::sub | ( | const std::string & | sub, |
bool | fail_if_missing = false |
||
) | const |
get const substructure by name
- Parameters
