Etymology

TableExprNodeRep is the (abstract) REPresentation of a node in a table expression tree.

Synopsis

TableExprNodeRep is the base class for all nodes in a table expression tree. It is used by the handle class TableExprNode.

The objects of this class are reference-counted to make it possible that the same object is reused.

Motivation

TableExprNodeRep and its derivations store a table select expression before actually evaluating it. It is also possible that the classes are 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 designed for these purposes.

To Do

• add selection by comparing with a set of values

	)

Construct a node.

casacore::TableExprNodeRep::TableExprNodeRep	(	NodeDataType	,
		ValueType	,
		OperType	,
		const Table &
	)

This constructor is called from the derived TableExprNodeRep.

casacore::TableExprNodeRep::TableExprNodeRep

(

const TableExprNodeRep &

)

Copy constructor.

virtual casacore::TableExprNodeRep::~TableExprNodeRep ( )

virtual

The destructor deletes all the underlying TableExprNode objects.

Member Function Documentation

virtual void casacore::TableExprNodeRep::adaptSetUnits ( const Unit &  )

virtual

Let a set node convert itself to the given unit.

The default implementation does nothing.

Reimplemented in casacore::TableExprNodeSet, and casacore::TableExprNodeSetElem.

virtual void casacore::TableExprNodeRep::applySelection ( const Vector< uInt > &  rownrs )

virtual

Re-create the column object for a selection of rows.

The default implementation does nothing.

Reimplemented in casacore::TableExprNodeArrayColumnString, casacore::TableExprNodeArrayColumnDComplex, casacore::TableExprNodeArrayColumnComplex, casacore::TableExprNodeArrayColumnDouble, casacore::TableExprNodeArrayColumnFloat, casacore::TableExprNodeArrayColumnInt64, casacore::TableExprNodeArrayColumnuInt, casacore::TableExprNodeArrayColumnInt, casacore::TableExprNodeRowid, casacore::TableExprNodeArrayColumnuShort, casacore::TableExprNodeArrayColumnShort, casacore::TableExprNodeArrayColumnuChar, casacore::TableExprNodeColumn, casacore::TableExprNodeArrayColumnBool, casacore::TableExprNodeArrayColumn, casacore::TableExprUDFNode, and casacore::TableExprUDFNodeArray.

const Record & casacore::TableExprNodeRep::attributes ( ) const

inline

Get the attributes.

void casacore::TableExprNodeRep::checkAggrFuncs

(

)

Throw an exception if an aggregate function is used in the expression node or its children.

void casacore::TableExprNodeRep::checkTablePtr ( const TENShPtr &  node )

inlineprotected

Check if this node uses the same table pointer.

Fill the Table object if it is still null.

Definition at line 754 of file ExprNodeRep.h.

References table_p.

static void casacore::TableExprNodeRep::checkTablePtr ( Table &  table, const TENShPtr &  node  )

staticprotected

virtual void casacore::TableExprNodeRep::convertConstChild ( )

protectedvirtual

If one of the children is a constant, convert its data type to that of the other operand (if appropriate).

This avoids that conversions are done for each get. The default implementation does nothing.

Reimplemented in casacore::TableExprNodeINInt.

static TENShPtr casacore::TableExprNodeRep::convertNode ( const TENShPtr &  thisNode, Bool  convertConstType  )

staticprotected

If the node is constant, it is evaluated and replaced by the appropriate TableExprNodeConst object.

If not constant, it calls the virtual ConvertConstChild function which can convert a constant child if appropriate.

static void casacore::TableExprNodeRep::createRange ( Block< TableExprRange > &  , TableExprNodeColumn *  , Double  start, Double  end  )

static

Create a range object from a column and an interval.

static void casacore::TableExprNodeRep::createRange ( Block< TableExprRange > &  )

static

Create a empty range object.

TableExprNodeRep::NodeDataType casacore::TableExprNodeRep::dataType ( ) const

inline

Get the data type of the derived TableExprNode object.

This is the data type of the resulting value. E.g. a compare of 2 numeric values results in a Bool, thus the data type of, say, TableExprNodeEQ<T> is always Bool. Function getInternalDT gives the internal data type, thus in the example above the data type of T.

Definition at line 704 of file ExprNodeRep.h.

virtual void casacore::TableExprNodeRep::disableApplySelection ( )

Do not apply the selection.

virtual void casacore::TableExprNodeRep::ranges ( Block< TableExprRange > &  )

virtual

Convert the tree to a number of range vectors which at least select the same things.

This function is very useful to convert the expression to some intervals covering the select expression. This can be used to do a rough fast selection via an index and do the the slower final selection on that much smaller subset. The function can only convert direct comparisons of columns with constants (via ==, !=, >, >=, < or <=) and their combinations using && or ||.
