Constructor & Destructor Documentation

◆ FunctionExpr() [1/2]

FunctionExpr::FunctionExpr ( const TQString & _name,
NArgExpr * args_ = 0 )

Definition at line 841 of file expression.cpp.

◆ FunctionExpr() [2/2]

FunctionExpr::FunctionExpr ( const FunctionExpr & expr)

Definition at line 854 of file expression.cpp.

◆ ~FunctionExpr()

FunctionExpr::~FunctionExpr ( )
virtual

Definition at line 863 of file expression.cpp.

Member Function Documentation

◆ builtInAggregates()

TQValueList< TQCString > FunctionExpr::builtInAggregates ( )
static

Definition at line 832 of file expression.cpp.

◆ copy()

FunctionExpr * FunctionExpr::copy ( ) const
virtual
Returns
a deep copy of this object.

Implements KexiDB::BaseExpr.

Definition at line 868 of file expression.cpp.

◆ debugString()

TQString FunctionExpr::debugString ( )
virtual

Reimplemented from KexiDB::BaseExpr.

Definition at line 873 of file expression.cpp.

◆ getQueryParameters()

void FunctionExpr::getQueryParameters ( QuerySchemaParameterList & params)
virtual

Collects query parameters (messages and types) reculsively and saves them to params. The leaf nodes are objects of QueryParameterExpr class.

Implements KexiDB::BaseExpr.

Definition at line 888 of file expression.cpp.

◆ isBuiltInAggregate()

bool FunctionExpr::isBuiltInAggregate ( const TQCString & fname)
static

Definition at line 907 of file expression.cpp.

◆ toString()

TQString FunctionExpr::toString ( QuerySchemaParameterValueListIterator * params = 0)
virtual
Returns
string as a representation of this expression element by running recursive calls. param, if not 0, points to a list item containing value of a query parameter (used in QueryParameterExpr).

Implements KexiDB::BaseExpr.

Definition at line 883 of file expression.cpp.

◆ type()

Field::Type FunctionExpr::type ( )
virtual

Reimplemented from KexiDB::BaseExpr.

Definition at line 893 of file expression.cpp.

◆ validate()

bool FunctionExpr::validate ( ParseInfo & parseInfo)
virtual

Reimplemented from KexiDB::BaseExpr.

Definition at line 899 of file expression.cpp.
