Member Function Documentation

◆ debugInternal()

void KDbFunctionExpressionData::debugInternal ( QDebug  dbg,
KDb::ExpressionCallStack callStack 
) const
overrideprotectedvirtual

Sends information about this expression to debug output dbg (internal).

Reimplemented from KDbExpressionData.

Definition at line 849 of file KDbFunctionExpression.cpp.

◆ typeInternal()

KDbField::Type KDbFunctionExpressionData::typeInternal ( KDb::ExpressionCallStack callStack) const
overrideprotectedvirtual
Todo:

Reimplemented from KDbExpressionData.

Definition at line 924 of file KDbFunctionExpression.cpp.

◆ validateInternal()

bool KDbFunctionExpressionData::validateInternal ( KDbParseInfo *  parseInfo,
KDb::ExpressionCallStack callStack 
)
overrideprotectedvirtual

Validation. Sets field, tablePositionForField and tableForQueryAsterisk members. See addColumn() in parse.y to see how it's used on column adding.

Reimplemented from KDbExpressionData.

Definition at line 1133 of file KDbFunctionExpression.cpp.
