Detailed Description

This object is held as the "value" in the Teuchos::ParameterList std::map.

This structure holds a Teuchos::any value and information on the status of this parameter (isUsed, isDefault, etc.). The type of parameter is chosen through the templated Set/Get methods.

inline

Templated set method that uses the input value type to determine the type of parameter.

Note
  • Invalidates any previous values stored by this object although it doesn't necessarily erase them.
  • Resets 'isUsed' functionality.

Set the value as an any object.

This wipes all other data including documentation strings.

Warning! Do not use function ths to set a sublist!

template<typename T >
T & Teuchos::ParameterEntry::getValue ( T *  ptr) const
inline

Templated get method that uses the input pointer type to determine the type of parameter to return.

Note
This method will cast the value to the type requested. If that type is incorrect, an std::exception will be thrown by the any_cast.

Definition at line 357 of file Teuchos_ParameterEntry.hpp.

any & Teuchos::ParameterEntry::getAny ( bool  activeQry = true)
inline

Direct access to the Teuchos::any data value underlying this object. The bool argument activeQry (default: true) indicates that the call to getAny() will set the isUsed() value of the ParameterEntry to true.

Definition at line 364 of file Teuchos_ParameterEntry.hpp.

const any & Teuchos::ParameterEntry::getAny ( bool  activeQry = true) const
inline

Constant direct access to the Teuchos::any data value underlying this object. The bool argument activeQry (default: true) indicates that the call to getAny() will set the isUsed() value of the ParameterEntry to true.

Definition at line 373 of file Teuchos_ParameterEntry.hpp.

Return the (optional) validator object.

Definition at line 402 of file Teuchos_ParameterEntry.hpp.

std::ostream & Teuchos::ParameterEntry::leftshift ( std::ostream &  os,
bool  printFlags = true 
) const

Output a non-list parameter to the given output stream.

The parameter is followed by "[default]" if it is the default value given through a Set method. Otherwise, if the parameter was unused (not accessed through a Get method), it will be followed by "[unused]". This function is called by the "std::ostream& operator<<".
