Enum Constant Detail

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.

Method Detail

values

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

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (RedisIO.Write.Method c : RedisIO.Write.Method.values())
    System.out.println(c);

Returns:

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

valueOf

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

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
