Detailed Description

null, a constant null value

Constructor & Destructor Documentation

NullProvider()

joda::query::NullProvider::NullProvider ( )

default

Member Function Documentation

duplicate()

std::unique_ptr< joda::query::IValueProvider > joda::query::NullProvider::duplicate ( ) const

overridevirtual

Returns

a pointer to a duplicate of the IValueProvider

Implements joda::query::IValueProvider.

getAtomValue()

RJValue joda::query::NullProvider::getAtomValue ( const RapidJsonDocument &  json, RJMemoryPoolAlloc &  alloc  ) const

overridevirtual

Gets an atomic value

Attention

isAtom() has to return true. If not this will result in undefined behavior

Parameters

json	The Rapidjsondocument to retrieve values from. (Or an empty RapidJsonDocument for const values)
alloc	A MemoryPoolAllocator to create the values with

Returns

a value containing the result

Implements joda::query::IValueProvider.

getName()

std::string joda::query::NullProvider::getName ( ) const

overridevirtual

Returns

The function name

Implements joda::query::IValueProvider.

getReturnType()

joda::query::IValueType joda::query::NullProvider::getReturnType ( ) const

overridevirtual

Returns

The type returned by the function

Implements joda::query::IValueProvider.

getValue()

const RJValue * joda::query::NullProvider::getValue ( const RapidJsonDocument &  json, RJMemoryPoolAlloc &  alloc  ) const

overridevirtual

Gets an value

Attention

isAtom() has to return false. If not this will result in undefined behavior

Parameters

json	The Rapidjsondocument to retrieve values from. (Or an empty RapidJsonDocument for const values)
alloc	A MemoryPoolAllocator to create the values with

Returns

a value-pointer containing the result

Implements joda::query::IValueProvider.

isAtom()

bool joda::query::NullProvider::isAtom ( ) const

overridevirtual

Reimplemented from joda::query::IValueProvider.

isConst()

bool joda::query::NullProvider::isConst ( ) const

overridevirtual

Returns

True if the Provider is const, false else

Implements joda::query::IValueProvider.
