Detailed Description

This holds a mapping of metadata objects. It inherits from Qt so it is copy on write. The mapping is done using strings. Each unique key can only hold a single metadata value. Refer to EMetadata for more information about the metadata system.

Member Function Documentation

at()

EMetadata EMetaObject::at

(

const QString &

key

)

const

Returns copy of metadata object with given key within the mapping of metadata objects. If the key does not exist a new null metadata value will be created and returned.

Parameters

key	Key of requested metadata object within the mapping of objects.

Returns

Copy of metadata object with given key.

begin() [1/2]

QMap< QString, EMetadata >::iterator EMetaObject::begin

(

)

Returns iterator to first metadata item in the mapping.

Returns

First metadata iterator.

begin() [2/2]

QMap< QString, EMetadata >::const_iterator EMetaObject::begin

(

)

const

Returns constant iterator to first metadata object in the mapping.

Returns

First metadata constant iterator.

cbegin()

QMap< QString, EMetadata >::const_iterator EMetaObject::cbegin

(

)

const

Returns constant iterator to first metadata object in the mapping.

Returns

First metadata constant iterator.

cend()

QMap< QString, EMetadata >::const_iterator EMetaObject::cend

(

)

const

Returns end of mapping constant iterator.

Returns

End of map constant iterator.

clear()

void EMetaObject::clear

(

)

Deletes all metadata values from the map making it an empty mapping.

end() [1/2]

QMap< QString, EMetadata >::iterator EMetaObject::end

(

)

Returns end of mapping iterator.

Returns

End of map iterator.

end() [2/2]

QMap< QString, EMetadata >::const_iterator EMetaObject::end

(

)

const

Returns end of mapping constant iterator.

Returns

End of map constant iterator.

insert()

void EMetaObject::insert	(	const QString &	key,
		const EMetadata &	value
	)

Inserts a new metadata value to the mapping with the given key. If a metadata value already exists with the given key it will be overwritten with the new given value.

Parameters

key	Key value where new metadata value will be mapped to.
value	The new metadata value to be inserted into the mapping.

isEmpty()

bool EMetaObject::isEmpty

(

)

const

Tests if the mapping is empty or not.

Returns

Returns true of the mapping is empty else returns false.

operator=()

EMetaObject & EMetaObject::operator=

(

const EMetaObject &

object

)

Assign this mapping to the one given. The map will not be copied until a write operation is performed.

Parameters

object

Map that this object will be assigned to.

Returns

Reference to this object.

operator[]() [1/2]

EMetadata & EMetaObject::operator[]

(

const QString &

key

)

Returns reference to metadata object with the given key. If no metadata object is mapped to the given key a new null metadata object is created, mapped with the given key, and returned as the reference.

Parameters

key	Key of requested metadata object within the mapping of objects.

Returns

Reference to metadata object.

operator[]() [2/2]

EMetadata EMetaObject::operator[]

(

const QString &

key

)

const

Returns copy of metadata object with the given key. If no metadata object is mapped to the given key a new null metadata object is created and returned.

Parameters

key	Key of requested metadata object within the mapping of objects.

Returns

Copy of metadata object.

size()

int EMetaObject::size

(

)

const

Gets the size of the mapping.

Returns

Size of the map.
