Enum Constant Summary

Enum Constants

Enum Constant	Description
CUSTOM	Allows to specify a custom ParallelExecutionConfigurationStrategy implementation via the mandatory "custom.class" configuration parameter to determine the desired configuration.
DYNAMIC	Computes the desired parallelism based on the number of available processors/cores multiplied by the "dynamic.factor" configuration parameter.
FIXED	Uses the mandatory "fixed.parallelism" configuration parameter as desired parallelism.

Field Summary

Fields

Modifier and Type	Field	Description
static String	CONFIG_CUSTOM_CLASS_PROPERTY_NAME	Property name used to specify the fully qualified class name of the ParallelExecutionConfigurationStrategy to be used by the CUSTOM configuration strategy.
static String	CONFIG_DYNAMIC_FACTOR_PROPERTY_NAME	Property name of the factor used to determine the desired parallelism by the DYNAMIC configuration strategy.
static String	CONFIG_FIXED_PARALLELISM_PROPERTY_NAME	Property name used to determine the desired parallelism by the FIXED configuration strategy.
static String	CONFIG_STRATEGY_PROPERTY_NAME	Property name used to determine the desired configuration strategy.

Method Summary

Modifier and Type	Method	Description
static DefaultParallelExecutionConfigurationStrategy	valueOf(String name)	Returns the enum constant of this type with the specified name.
static DefaultParallelExecutionConfigurationStrategy[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

FIXED

public static final DefaultParallelExecutionConfigurationStrategy FIXED

Uses the mandatory "fixed.parallelism" configuration parameter as desired parallelism.

DYNAMIC

public static final DefaultParallelExecutionConfigurationStrategy DYNAMIC

Computes the desired parallelism based on the number of available processors/cores multiplied by the "dynamic.factor" configuration parameter.

CUSTOM

public static final DefaultParallelExecutionConfigurationStrategy CUSTOM

Allows to specify a custom ParallelExecutionConfigurationStrategy implementation via the mandatory "custom.class" configuration parameter to determine the desired configuration.

Field Detail

CONFIG_STRATEGY_PROPERTY_NAME

public static final String CONFIG_STRATEGY_PROPERTY_NAME

Property name used to determine the desired configuration strategy.

Value must be one of dynamic, fixed, or custom.

Constant Field Values

CONFIG_FIXED_PARALLELISM_PROPERTY_NAME

public static final String CONFIG_FIXED_PARALLELISM_PROPERTY_NAME

Property name used to determine the desired parallelism by the FIXED configuration strategy.

No default value; must be an integer.

FIXED, Constant Field Values

CONFIG_DYNAMIC_FACTOR_PROPERTY_NAME

public static final String CONFIG_DYNAMIC_FACTOR_PROPERTY_NAME

Property name of the factor used to determine the desired parallelism by the DYNAMIC configuration strategy.

Value must be a decimal number; defaults to 1.

CONFIG_CUSTOM_CLASS_PROPERTY_NAME

@API(status=EXPERIMENTAL,
     since="5.3")
public static final String CONFIG_CUSTOM_CLASS_PROPERTY_NAME

Property name used to specify the fully qualified class name of the ParallelExecutionConfigurationStrategy to be used by the CUSTOM configuration strategy.

Method Detail

values

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

Returns:

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

valueOf

public static DefaultParallelExecutionConfigurationStrategy 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
