Enum Constant Details

APPEND

public static final RedisIO.Write.Method APPEND

Use APPEND command. If key already exists and is a string, this command appends the value at the end of the string.

SET

public static final RedisIO.Write.Method SET

Use SET command. If key already holds a value, it is overwritten.

LPUSH

public static final RedisIO.Write.Method LPUSH

Use LPUSH command. Insert value at the head of the list stored at key. If key does not exist, it is created as empty list before performing the push operations. When key holds a value that is not a list, an error is returned.

RPUSH

public static final RedisIO.Write.Method RPUSH

Use RPUSH command. Insert value at the tail of the list stored at key. If key does not exist, it is created as empty list before performing the push operations. When key holds a value that is not a list, an error is returned.

SADD

public static final RedisIO.Write.Method SADD

Use SADD command. Insert value in a set. Duplicated values are ignored.

PFADD

public static final RedisIO.Write.Method PFADD

Use PFADD command. Insert value in a HLL structure. Create key if it doesn't exist

INCRBY

public static final RedisIO.Write.Method INCRBY

Use INCBY command. Increment counter value of a key by a given value.

DECRBY

public static final RedisIO.Write.Method DECRBY

Use DECRBY command. Decrement counter value of a key by given value.

Method Details

values

public static RedisIO.Write.Method[] values()

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static RedisIO.Write.Method valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:
