Detailed Description

template<class Calc>
class joda::query::UnaryNumberProvider< Calc >

Template class used for all unary mathamatical functions. The template argument has to be a struct with the following attributes/functions.

struct <StructName> {
 static constexpr auto name = "<Name>";
 static constexpr IValueType retType = <IValueType returntype>;
 inline static RJValue calculate(double val, RJMemoryPoolAlloc &alloc) {
return <result>; }; inline static RJValue calculate(u_int64_t val,
RJMemoryPoolAlloc &alloc) {  return <result>;  }; inline static RJValue
calculate(int64_t val, RJMemoryPoolAlloc &alloc) {  return <result>; };
};

Here is the caller graph for this function:

duplicate()

template<class Calc >

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

inlineoverridevirtual

Returns

a pointer to a duplicate of the IValueProvider

Implements joda::query::IValueProvider.

Here is the call graph for this function:

getAtomValue()

template<class Calc >

RJValue joda::query::UnaryNumberProvider< Calc >::getAtomValue ( const RapidJsonDocument &  json, RJMemoryPoolAlloc &  alloc  ) const

inlineoverridevirtual

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.

Here is the call graph for this function:

getName()

template<class Calc >

std::string joda::query::UnaryNumberProvider< Calc >::getName ( ) const

inlineoverridevirtual

Returns

The function name

Implements joda::query::IValueProvider.

getReturnType()

template<class Calc >

joda::query::IValueType joda::query::UnaryNumberProvider< Calc >::getReturnType ( ) const

inlineoverridevirtual

Returns

The type returned by the function

Implements joda::query::IValueProvider.

getValue()

template<class Calc >

const RJValue* joda::query::UnaryNumberProvider< Calc >::getValue ( const RapidJsonDocument &  json, RJMemoryPoolAlloc &  alloc  ) const

inlineoverridevirtual

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.

Here is the call graph for this function:

isConst()

template<class Calc >

bool joda::query::UnaryNumberProvider< Calc >::isConst ( ) const

inlineoverridevirtual

Returns

True if the Provider is const, false else

Implements joda::query::IValueProvider.

toString()

template<class Calc >

std::string joda::query::UnaryNumberProvider< Calc >::toString ( ) const

inlineoverridevirtual

Returns

A textual representation of the IValueProvider

Reimplemented from joda::query::IValueProvider.
