Detailed Description

template<typename T>
class delpi::OptionValue< T >

Represents an optional value in dLinear.

There are four ways that an option can have its value – by default, by a command-line argument, by a set-info/set-option command from a .smt2 file, and a manual update in a code. We define an order in these types and make sure that an update is executed only if it is requested by the same type or a higher type. For example, a value set by command-line cannot be changed by an updated requested from a file.

Template Parameters

T	Type of the value the class will hold.

Member Enumeration Documentation

Type

template<typename T>

enum class delpi::OptionValue::Type

strong

Type of the value.

Each type encodes a priority, and an update is executed only if it is requested by the same type or a higher type.

Enumerator
DEFAULT	Default value.
FROM_FILE	Updated by a set-option/set-info in a file.
FROM_COMMAND_LINE	Updated by a command-line argument.
FROM_CODE	Explicitly updated from code.

Definition at line 39 of file OptionValue.hpp.

Constructor & Destructor Documentation

OptionValue()

template<typename T>

delpi::OptionValue< T >::OptionValue ( T value )

inlineexplicit

Constructs an option value with value.

Parameters

value

value to be held.

Definition at line 50 of file OptionValue.hpp.

Member Function Documentation

operator=() [1/2]

template<typename T>

OptionValue & delpi::OptionValue< T >::operator= ( const T & value )

inline

Copy-assign operator for T.

Note

It sets value with Type::FROM_CODE type.

Definition at line 65 of file OptionValue.hpp.

operator=() [2/2]

template<typename T>

OptionValue & delpi::OptionValue< T >::operator= ( T && value )

inline

Move-assign operator for T.

Note

It sets value with Type::FROM_CODE type.

Definition at line 75 of file OptionValue.hpp.

SetFromCommandLine()

template<typename T>

void delpi::OptionValue< T >::SetFromCommandLine ( const T & value )

inline

Sets the value to value which is given by a command-line argument.

It sets the type to Type::FROM_COMMAND_LINE. It does nothing if the current type is Type::FROM_CODE.

Parameters

value

new value, given by a command-line argument.

Definition at line 92 of file OptionValue.hpp.

SetFromFile()

template<typename T>

void delpi::OptionValue< T >::SetFromFile ( const T & value )

inline

Sets the value to value which is provided from a file.

It sets the type to Type::FROM_FILE. It does nothing if the current type is Type::FROM_COMMAND_LINE or Type::FROM_CODE.

Parameters

value

new value, provided from a file.
