int TRedis::del

(

const QByteArrayList &

keys

)

Removes the specified keys.

A key is ignored if it does not exist.

exists()

(

)

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,

inline

hlen()

int TRedis::hlen

(

const QByteArray &

key

)

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

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

setsNx()

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

inline
