Constructor & Destructor Documentation

JsonDouble()

ola::web::JsonDouble::JsonDouble ( double  value )

explicit

Create a new JsonDouble.

Parameters

value

the double to use.

Member Function Documentation

Accept() [1/2]

void ola::web::JsonDouble::Accept ( JsonValueVisitorInterface *  visitor )

inlinevirtual

The Accept method for the visitor pattern.

This can be used to traverse the Json Tree in a type-safe manner.

Implements ola::web::JsonValue.

Accept() [2/2]

void ola::web::JsonDouble::Accept ( JsonValueConstVisitorInterface *  visitor ) const

inlinevirtual

The Accept (const) method for the visitor pattern.

This can be used to traverse the Json Tree in a type-safe manner.

Implements ola::web::JsonValue.

AsDouble()

bool ola::web::JsonDouble::AsDouble ( const DoubleRepresentation &  rep, double *  out  )

static

Convert a DoubleRepresentation to a double value.

Parameters

	rep	the DoubleRepresentation
[out]	out	The value stored as a double.

Returns

false if the DoubleRepresentation can't fit in a double.

AsString()

string ola::web::JsonDouble::AsString ( const DoubleRepresentation &  rep )

static

Convert the DoubleRepresentation to a string.

Parameters

rep	the DoubleRepresentation

Returns

The string representation of the DoubleRepresentation.

operator==()

bool ola::web::JsonDouble::operator== ( const JsonValue &  other ) const

inlinevirtual

Equality operator.

This implements equality as defined in section 3.6 of the JSON Schema Core document.

Implements ola::web::JsonValue.

Value()

double ola::web::JsonDouble::Value ( ) const

inline

Returns the value as a double.

This may be incorrect if the value exceeds the storage space of the double.
