◆ FormatValue()

std::string BoolSettingDesc::FormatValue ( const void * object ) const

overridevirtual

Format the value of the setting associated with this object.

Parameters

buf	The before of the buffer to format into.
last	The end of the buffer to format into.
object	The object the setting is in.

Reimplemented from IntSettingDesc.

Definition at line 752 of file settings.cpp.

References IntSettingDesc::Read().

◆ IsBoolSetting()

bool BoolSettingDesc::IsBoolSetting ( ) const

inlineoverridevirtual

Check whether this setting is a boolean type setting.

Returns: True when the underlying type is an integer.

Reimplemented from IntSettingDesc.

Definition at line 257 of file settings_internal.h.

◆ ParseSingleValue()

std::optional< bool > BoolSettingDesc::ParseSingleValue ( const char * str )

static

Find whether a string was a boolean true or a boolean false.

Parameters

str	the current value of the setting for which a value needs found.

Returns: Either true/false, or nullopt if no boolean value found.

◆ ParseValue()

size_t BoolSettingDesc::ParseValue ( const char * str ) const

overridevirtual

Convert a string representation (external) of an integer-like setting to an integer.

Parameters

str	Input string that will be parsed based on the type of desc.

Returns: The value from the parse string, or the default value of the setting.
