Member Function Documentation

◆ FormatValue()

std::string NullSettingDesc::FormatValue ( const void *  object) const
inlineoverridevirtual

Format the value of the setting associated with this object.

Parameters
bufThe before of the buffer to format into.
lastThe end of the buffer to format into.
objectThe object the setting is in.

Implements SettingDesc.

Definition at line 378 of file settings_internal.h.

◆ IsDefaultValue()

bool NullSettingDesc::IsDefaultValue ( void *  object) const
inlineoverridevirtual

Check whether the value is the same as the default value.

Parameters
objectThe object the setting is in.
Returns
true iff the value is the default value.

Implements SettingDesc.

Definition at line 381 of file settings_internal.h.

◆ IsSameValue()

bool NullSettingDesc::IsSameValue ( const IniItem item,
void *  object 
) const
inlineoverridevirtual

Check whether the value in the Ini item is the same as is saved in this setting in the object.

It might be that determining whether the value is the same is way more expensive than just writing the value. In those cases this function may unconditionally return false even though the value might be the same as in the Ini item.

Parameters
itemThe Ini item with the content of this setting.
objectThe object the setting is in.
Returns
True if the value is definitely the same (might be false when the same).

Implements SettingDesc.

Definition at line 380 of file settings_internal.h.

◆ ParseValue()

void NullSettingDesc::ParseValue ( const IniItem item,
void *  object 
) const
inlineoverridevirtual

Parse/read the value from the Ini item into the setting associated with this object.

Parameters
itemThe Ini item with the content of this setting.
objectThe object the setting is in.

Implements SettingDesc.

Definition at line 379 of file settings_internal.h.
