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

~TableExprNodeRep()

virtual casacore::TableExprNodeRep::~TableExprNodeRep ( )

virtual

The destructor deletes all the underlying TableExprNode objects.

Member Function Documentation

adaptSetUnits()

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.

applySelection()

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

virtual

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

The default implementation does nothing.

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

attributes()

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

inline

Get the attributes.

checkAggrFuncs()

void casacore::TableExprNodeRep::checkAggrFuncs

(

)

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

checkTablePtr() [1/2]

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.

checkTablePtr() [2/2]

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

staticprotected

convertConstChild()

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.

convertNode()

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.

createRange() [1/2]

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

static

Create a empty range object.

createRange() [2/2]

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

static

Create a range object from a column and an interval.

dataType()

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 ( )

virtual

Do not apply the selection.
