Method Detail

values

public static ShardingStrategyType[] 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 (ShardingStrategyType c : ShardingStrategyType.values())
    System.out.println(c);

Returns:

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

valueOf

public static ShardingStrategyType valueOf(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:

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

NullPointerException - if the argument is null

createConfiguration

public abstract ShardingStrategyConfiguration createConfiguration(String shardingAlgorithmName,
                                                                  String shardingColumn)

Get the sharding strategy configuration.

Parameters:

shardingAlgorithmName - sharding algorithm name

shardingColumn - sharding column

Returns:

sharding strategy configuration

getImplementedClass

public abstract Class<? extends ShardingStrategyConfiguration> getImplementedClass()

Get the class that implements the strategy.

Returns:

Class implementing the strategy

getConfigurationContents

public abstract Collection<String> getConfigurationContents(ShardingStrategyConfiguration strategyConfiguration)

Get the content in the configuration.

Parameters:

strategyConfiguration - sharding strategy configuration.

Returns:

Content list

isValid

public abstract boolean isValid(String shardingColumn)

Check whether the configuration is valid.

Parameters:

shardingColumn - sharding column

Returns:

valid or invalid

getValueOf

public static ShardingStrategyType getValueOf(String name)

Returns the sharding strategy type.

Parameters:

name - name

Returns:

sharding strategy type

getValueOf

public static ShardingStrategyType getValueOf(ShardingStrategyConfiguration shardingStrategyConfiguration)

Returns the sharding strategy type.

Parameters:

shardingStrategyConfiguration - Implementation class of sharding strategy configuration

Returns:

sharding strategy type

contain

public static boolean contain(String name)

Determine whether the specified type is included.

Parameters:

name - name

Returns:

have data or not
