Constructor & Destructor Documentation

te::da::FunctionNoArgsEncoder::FunctionNoArgsEncoder ( const std::string & name )

inline

Constructor.

Parameters

name	The function alias as understood by some data source implmentation.

Definition at line 54 of file FunctionNoArgsEncoder.h.

te::da::FunctionNoArgsEncoder::~FunctionNoArgsEncoder ( )

inline

Destructor.

Definition at line 57 of file FunctionNoArgsEncoder.h.

void te::da::FunctionNoArgsEncoder::toSQL	(	const Function &	f,
		std::string &	buff,
		SQLVisitor &	v
	)		const

virtual

It encodes the function to a SQL notation.

This method will encode the function in prefix unary operator notation: (op operand). For example, the '-' function is encoded as: -A.

Parameters

f	The function to be translated to a SQL notation.
buff	The destination string buffer where the translation will be written.
v	The SQL visitor that will be used to visit the arguments expression.

std::string te::da::SQLFunctionEncoder::m_name

protectedinherited

The alias to the function.
