Detailed Description

An object containing all the information about a data type – the primitive DataType; for DataType::TUPLEs, the Tuple's Schema; and for DataType::LISTs, the List elements' own CompleteDataType.

To get a CompleteDataType object, call the type-appropriate static method, eg. for a Boolean CompleteDatatType object, call CompleteDataType::forBool(); for a Tuple CompleteDataType, call CompleteDataType::forTuple(s) with some Schema s; for a List CompleteDataType, call CompleteDataType::forList(cdt) with some CompleteDataType cdt; and so on.

CompleteDataTypes are immutable; once created they may not be changed.

Constructor & Destructor Documentation

sb::CompleteDataType::CompleteDataType ( const CompleteDataType cdt)
inline

Copy constructor.

sb::CompleteDataType::~CompleteDataType ( )
inline

Destructor.

Member Function Documentation

std::string sb::CompleteDataType::as_string ( ) const
inline

Returns a string representation of this CompleteDataType.

int sb::CompleteDataType::compare ( const CompleteDataType fv) const

Compare the current CompleteDataType against the provided CompleteDataType by base type (eg DataType::BOOL, ::INT, ::TUPLE, etc).

Therefore, for example a LIST of type INT and a LIST of type TUPLE are equal.

Returns
-1 if the current CompleteDataType is less than the provided CompleteDataType, 0 if the current is equal to the provided CompleteDataType, and 1 if the current is greater than the provided CompleteDataType.
static const CompleteDataType& sb::CompleteDataType::forBlob ( )
inlinestatic

Return a CompleteDataType of type DataType::BLOB.

static const CompleteDataType& sb::CompleteDataType::forBool ( )
inlinestatic

Return a CompleteDataType of type DataType::BOOL.

static const CompleteDataType sb::CompleteDataType::forCapture ( const std::string &  captureName)
inlinestatic

Return a CompleteDataType of type DataType::CAPTURE with the given capture type name.

static const CompleteDataType& sb::CompleteDataType::forDouble ( )
inlinestatic

Return a CompleteDataType of type DataType::DOUBLE.

static const CompleteDataType sb::CompleteDataType::forFunction ( const Schema argumentSchema,
const CompleteDataType returnType 
)
inlinestatic

Return a CompleteDataType of type DataType::FUNCTION with the given argument schema and return type.

static const CompleteDataType& sb::CompleteDataType::forInt ( )
inlinestatic

Return a CompleteDataType of type DataType::INT.

static const CompleteDataType sb::CompleteDataType::forList ( const CompleteDataType elemType)
inlinestatic

Return a CompleteDataType of type DataType::LIST with the given CompleteDataType as the type of its elements.

static const CompleteDataType& sb::CompleteDataType::forLong ( )
inlinestatic

Return a CompleteDataType of type DataType::LONG.

static const CompleteDataType sb::CompleteDataType::forSimpleType ( const DataType type)
static

Convenience method.

Return the CompleteDataType appropriate to the given DataType. Invalid on DataType::TUPLE and DataType::LIST, since they require extra information to fully specify their CompleteDataType.

static const CompleteDataType& sb::CompleteDataType::forString ( )
inlinestatic

Return a CompleteDataType of type DataType::STRING.

static const CompleteDataType& sb::CompleteDataType::forTimestamp ( )
inlinestatic

Return a CompleteDataType of type DataType::TIMESTAMP.

static const CompleteDataType sb::CompleteDataType::forTuple ( const Schema s)
inlinestatic

Return a CompleteDataType of type DataType::TUPLE with the given Schema.

const Schema& sb::CompleteDataType::getArgumentSchema ( ) const
inline

If this CompleteDataType is a function, return its argument schema.

const CompleteDataType& sb::CompleteDataType::getElementCompleteType ( ) const
inline

If this CompleteDataType has an element type, returns the element CompleteDataType.

For all other types, returns a null CompleteDataType.

Referenced by sb::Field::getElementCompleteType().

const CompleteDataType& sb::CompleteDataType::getReturnType ( ) const
inline

If this CompleteDataType is a function, return its return type.

const Schema sb::CompleteDataType::getSchema ( ) const
inline

If this CompleteDataType has a nested tuple, return its Schema.

For all other types, return a null Schema.

const DataType& sb::CompleteDataType::getType ( ) const
inline

Return the primitive DataType of the CompleteDataType.

bool sb::CompleteDataType::hasElementType ( ) const
inline

Returns true if this CompleteDataType has an element CompleteDataType (eg it is a DataType::LIST of DataType::INTs, the latter being its element type).

bool sb::CompleteDataType::hasSchema ( )
inline

Returns true if this CompleteDataType contains a Schema (eg it is a DataType::TUPLE).

CompleteDataType& sb::CompleteDataType::operator= ( const CompleteDataType cdt)

Assignment operator.
