◆ del() [1/2]

bool TRedis::del ( const QByteArray &  key)

Removes the specified key.

A key is ignored if it does not exist.

◆ del() [2/2]

int TRedis::del ( const QByteArrayList &  keys)

Removes the specified keys.

A key is ignored if it does not exist.

◆ exists()

bool TRedis::exists ( const QByteArray &  key)

Returns true if the key exists; otherwise returns false.

◆ flushDb()

◆ get()

QByteArray TRedis::get ( const QByteArray &  key)

Returns the value associated with the key; otherwise returns an empty byte array.

◆ gets()

QString TRedis::gets ( const QByteArray &  key)
inline

Returns the string associated with the key; otherwise returns a null string.

◆ getSet()

QByteArray TRedis::getSet ( const QByteArray &  key,
const QByteArray &  value 
)

Atomically sets the key to the value and returns the old value stored at the key.

◆ getsSets()

QString TRedis::getsSets ( const QByteArray &  key,
const QString &  value 
)
inline

Atomically sets the key to the string value and returns the old string value stored at the key.

◆ hdel() [1/2]

bool TRedis::hdel ( const QByteArray &  key,
const QByteArray &  field 
)

◆ hdel() [2/2]

int TRedis::hdel ( const QByteArray &  key,

const QByteArray &  field 
)

◆ hgetAll()

QList< QPair< QByteArray, QByteArray > > TRedis::hgetAll ( const QByteArray &  key)

◆ hgets()

QString TRedis::hgets ( const QByteArray &  key,
const QByteArray &  field 
)
inline

◆ hlen()

◆ hset()

bool TRedis::hset ( const QByteArray &  key,
const QByteArray &  field,
const QByteArray &  value 
)

◆ hsetNx()

bool TRedis::hsetNx ( const QByteArray &  key,
const QByteArray &  field,
const QByteArray &  value 
)

◆ hsets()

bool TRedis::hsets ( const QByteArray &  key,
const QByteArray &  field,
const QString &  value 
)
inline

◆ hsetsNx()

bool TRedis::hsetsNx ( const QByteArray &  key,
const QByteArray &  field,
const QString &  value 
)
inline

◆ isOpen()

bool TRedis::isOpen ( ) const

Returns true if the Redis connection is open; otherwise returns false.

◆ lindex()

QByteArray TRedis::lindex ( const QByteArray &  key,
int  index 
)

Returns the element at the index in the list stored at the key.

◆ lindexs()

QString TRedis::lindexs ( const QByteArray &  key,
int  index 
)
inline

Returns the string at the index in the list stored at the key.

◆ llen()

int TRedis::llen ( const QByteArray &  key)

Returns the length of the list stored at the key.

◆ lpush()

int TRedis::lpush ( const QByteArray &  key,
const QByteArrayList &  values 
)

Inserts all the values at the tail of the list stored at the key.

Returns the length of the list after the push operation.

◆ lpushs()

int TRedis::lpushs ( const QByteArray &  key,
const QStringList &  values 
)
inline

Inserts all the string values at the tail of the list stored at the key.

Returns the length of the list after the push operation.

◆ lrange()

QByteArrayList TRedis::lrange ( const QByteArray &  key,
int  start,
int  end = -1 
)

Returns the specified elements of the list stored at the key.

◆ lranges()

QStringList TRedis::lranges ( const QByteArray &  key,
int  start,
int  end = -1 
)
inline

Returns the specified elements of the list stored at the key.

◆ rpush()

int TRedis::rpush ( const QByteArray &  key,
const QByteArrayList &  values 
)

Inserts all the values at the tail of the list stored at the key.

Returns the length of the list after the push operation.

◆ rpushs()

int TRedis::rpushs ( const QByteArray &  key,
const QStringList &  values 
)
inline

Inserts all the string values at the tail of the list stored at the key.

Returns the length of the list after the push operation.

◆ set()

bool TRedis::set ( const QByteArray &  key,
const QByteArray &  value 
)

Sets the key to hold the value.

If the key already holds a value, it is overwritten, regardless of its type.

◆ setEx()

bool TRedis::setEx ( const QByteArray &  key,
const QByteArray &  value,
int  seconds 
)

Sets the key to hold the value and set the key to timeout after a given number of seconds.

◆ setNx()

bool TRedis::setNx ( const QByteArray &  key,
const QByteArray &  value 
)

Set the key to hold the value if key does not exist.

In that case, it is equal to SET. When key already holds a value, no operation is performed.

◆ sets()

bool TRedis::sets ( const QByteArray &  key,
const QString &  value 
)
inline

Sets the key to hold the string value.

If the key already holds a value, it is overwritten, regardless of its type.

◆ setsEx()

bool TRedis::setsEx ( const QByteArray &  key,
const QString &  value,
int  seconds 
)
inline
