// <etymology>
// TableExprNode represents a node in the tree reflecting a
// table select expression.
// </etymology>

// <synopsis> 
// TableExprNode is the class to store a table select expression,
// making it possible to select rows from the table. The selected
// rows form a table which is a view of the original table.
// <p>
// TableExprNode is a handle class for the counted referenced class
// TableExprNodeRep.
// Classes (like TableExprNodePlusXX) derived from TableExprNodeRep
// hold the individual
// nodes in the expression, i.e. the operators and operands. The nodes
// form a binary tree reflecting the expression.
// E.g. the expression 2*COLUMN results in the node TableExprNodeTimes
// with its children TableExprNodeConst and TableExprNodeColumn.
// Constant subexpressions (like 2*3) are evaluated immediately and
// only the result is stored as a node.
// <p>
// There are a few TableExprNode constructors taking a constant scalar or array.
// In this way constant value are automatically converted to the
// appropriate TableExprNodeConst object.
// <p>
// The derived classes also reflect the data type of the node.
// Data types Bool, Int64, Double, DComplex and String are used.
// Char, uChar, Short, uShort, Int and uInt are converted to Int64,
// float to Double, and Complex to DComplex.
// Binary operators +, -, *, /, %, &, }, ^, ==, >=, >, <, <= and != are
// recognized. Also &&, ||, parentheses and unary +, -, ~ and ! are recognized.
// For strings the binary operator + can also be used.
// The operators have the normal C++ precedence.
// Furthermore functions (such as sin, max, ceil) can be used in an expression.
// <br>Operator() can be used to take a slice from an array.
// <p>
// The Table function col has to be used to create a TableExprNode
// object for a column in the table. The Table
// <linkto file="Table.h#keycol">operator()</linkto> can be used
// the do the actual selection from the top TableExprNode object.
// </synopsis> 

// <example>
// <srcblock>
//   // Select from table X all rows where column RA<5 and where column
//   // SWITCH is true.
//   Table table("X");
//   Table subtable = table(table.col("RA") < 5 && table.col("SWITCH"));
//
//   // Select from that result all rows where the concatenation of
//   // the strings in columns STR1 and STR2 is equal to the string
//   // in keyword STRKEY.
//   Table subsub = subtable(subtable.col("STR1") + subtable.col("STR2")
//                           == subtable.key("STRKEY"));
// </srcblock>
// </example>

// <motivation>
// Having TableExprNode as a handle class makes it possible to
// handle temporary objects created by the compiler in a smooth way.
// TableExprNode and its derivations allow to store an expression
// before actually evaluating it. This also allows the classes to
// be used by the table expression parser defined in TableParse and
// TableGram.
//
// For each operator a special derived class is implemented.
// Another approach could have been to store the operator as
// a flag and switch on that. However, that causes extra overhead
// and the C++ virtual function mechanism is the designed for
// these purposes.
// </motivation>

// <todo asof="$DATE:$">
//# A List of bugs, limitations, extensions or planned refinements.
//   <li> add operations on arrays
//   <li> add selection by comparing with a set of values
// </todo>
