	Insert the given value at the current cascading level.

const QVariant	value (const QString &key, const QVariant &defValue=QVariant()) const
	Returns the value of the given key. If the map at this level doesn't have this key, it cascades to a higher-level. If it doesn't find the key if will fallback to the defValue supplied.

Detailed Description

A cascading map is a Hierarchical QVariantMap.

When retrieving an item, it fist tries to find the item at this level, if it does't find the item it tries the parent item

explicit

Member Function Documentation

◆ boolValue()

bool edbee::CascadingQVariantMap::boolValue	(	const QString &	key,
		bool	defValue = false ) const

Returns the default boolean value.

◆ deleteParents()

void edbee::CascadingQVariantMap::deleteParents ( )

This helper method deletes all containing parents recursively Tough this doesnt' feel quite correct (it uses references to parent) it makes managing the map a bit easier.

◆ doubleValue()

double edbee::CascadingQVariantMap::doubleValue	(	const QString &	key,
		double	defValue = 0.0 ) const

Returns a double value.

◆ insert()

void edbee::CascadingQVariantMap::insert	(	const QString &	key,
		const QVariant &	value )

Insert the given value at the current cascading level.

Parameters

key	the name of the key to set
value	the value to set

◆ intValue()

int edbee::CascadingQVariantMap::intValue	(	const QString &	key,
		int	defValue = 0 ) const

Method to quickly fetch int items.

◆ parent()

CascadingQVariantMap * edbee::CascadingQVariantMap::parent ( ) const

Returns the parent of this map.

◆ root()

CascadingQVariantMap * edbee::CascadingQVariantMap::root ( )

This method finds the 'root variant map.

◆ setQVariantMap()

void edbee::CascadingQVariantMap::setQVariantMap ( const QVariantMap & map )

Sets the variant mapt to the given map.

◆ stringValue()

const QString edbee::CascadingQVariantMap::stringValue	(	const QString &	key,
		const QString &	defValue = QString() ) const

Method to quickly fetch a string item.

◆ value()

const QVariant edbee::CascadingQVariantMap::value	(	const QString &	key,
		const QVariant &	defValue = QVariant() ) const

Returns the value of the given key. If the map at this level doesn't have this key, it cascades to a higher-level. If it doesn't find the key if will fallback to the defValue supplied.
