Detailed Description

The KDbSqlString class abstracts low-level information about a single string value returned by KDbSqlRecord.

KDbSqlString exists for optimization purposes. KDbSqlRecord can return KDbSqlString objects to avoid premature converting to QString or QByteArray. This way memory allocations are not required.

Constructor & Destructor Documentation

◆ KDbSqlString() [1/2]

KDbSqlString::KDbSqlString ( )
inline

Creates an empty string object.

Definition at line 36 of file KDbSqlString.h.

◆ KDbSqlString() [2/2]

KDbSqlString::KDbSqlString ( const char *  s,
quint64  len 
)
inline

Creates string object from raw string s, of specified length.

Definition at line 39 of file KDbSqlString.h.

Member Function Documentation

◆ isEmpty()

bool KDbSqlString::isEmpty ( ) const
inline
Returns
true if this string value is empty. Here, NULL values are considered empty too.

Definition at line 42 of file KDbSqlString.h.

◆ rawDataToByteArray()

QByteArray KDbSqlString::rawDataToByteArray ( ) const
inline
Returns
string value converted to bytea array For optimization, raw string data is used via, see QByteArray::fromRawData() for details. The caller must not delete data or modify the parent KDbSqlRecord object directly as long as the returned QByteArray exists.
