Synopsis

This class represents a function in a table select tree. The rownumber function is represented by class TableExprNodeRownr. The rowid function is represented by class TableExprNodeRowid. The rand function is represented by class TableExprNodeRandom.

When one wants to add a function to the table selection grammar, the following has to be done:

Add the function to the enum below.
Implement the function in the get functions in ExprFuncNode(Array).cc.
Implement the function in the checkOperands in ExprFuncNode.cc.
Declare and define the function in ExprNode.h (for C++ binding).
Add the function to findFunc in TableParse.cc (for TaQL).

static String casacore::TableExprFuncNode::stringValue	(	Bool	val,
		const String &	fmt,
		Int	width
	)

static

Convert a value to a string.

If fmt is empty, ostringstream is used. Otherwise the printf-like format is used. If possible, a double value is converted to radians if formatted as angle.
