void ola::web::JsonArray::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.

void ola::web::JsonArray::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.

void ola::web::JsonArray::Append ( const std::string & value )

inline

Append a string value to the array.

Parameters

value the value to append

void ola::web::JsonArray::Append ( const char * value )

inline

Append a string value to the array.

Parameters

value the value to append

void ola::web::JsonArray::Append ( unsigned int i )

inline

Append an unsigned int value to the array.

Parameters

i	the value to append

void ola::web::JsonArray::Append ( int i )

inline

Append an int value to the array.

Parameters

i	the value to append

void ola::web::JsonArray::Append ( bool value )

inline

Append a bool value to the array.

Parameters

value the value to append

JsonArray* ola::web::JsonArray::AppendArray ( )

inline

Append a JsonArray to the array.

Returns: the new JsonArray. Ownership is not transferred and the pointer is valid for the lifetime of this JsonArray.

JsonObject* ola::web::JsonArray::AppendObject ( )

inline

Append a JsonObject to the array.

Returns: the new JsonObject. Ownership is not transferred and the pointer is valid for the lifetime of this JsonArray.

void ola::web::JsonArray::AppendValue ( JsonValue * value )

inline

Append a JsonValue to the array.

Parameters

value the JsonValue to append, ownership is transferred.

const JsonValue * ola::web::JsonArray::ElementAt ( unsigned int i ) const

Return the element at index i.

Returns: The JsonValue at i, of NULL if the index is out of range.

bool ola::web::JsonArray::Equals ( const JsonArray & ) const

virtual

Check if this JsonValue equals a JsonArray.

Returns: true if the two values are equal, false otherwise.

Reimplemented from ola::web::JsonValue.

bool ola::web::JsonArray::InsertElementAt	(	uint32_t	index,
		JsonValue *	value
	)

Inserts the JsonValue at the specified index.

Parameters

index	the index to insert at.
value	the new JsonValue. Ownership is transferred.

Returns: true if the index is within the current array, false otherwise.

Any elements at or above the index are shifted one to the right.

bool ola::web::JsonArray::IsEmpty ( ) const

inline

Check if there are elements within the array.

Returns: true if the array is empty, false if there are elements.

JsonValue * ola::web::JsonArray::LookupElementWithIter ( JsonPointer::Iterator * iterator )

virtual

Lookup the Value referred to by the Iterator.

This is used by recursively by JsonValue classes. You should call LookupElement() instead.

Implements ola::web::JsonValue.

bool ola::web::JsonArray::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.

bool ola::web::JsonArray::RemoveElementAt ( uint32_t index )

Remove the JsonValue at the specified index.

Parameters

index the index of the value to remove

Returns: true if the index is within the current array, false otherwise.

bool ola::web::JsonArray::ReplaceElementAt	(	uint32_t	index,
		JsonValue *	value
	)

Replace the JsonValue at the specified index.

Parameters

index	the index of the value to replace.
value	the new JsonValue. Ownership is transferred.

Returns: true if the index is within the current array, false otherwise.
