Enum MLContext.ExecutionType

java.lang.Object

java.lang.Enum<MLContext.ExecutionType>

org.apache.sysds.api.mlcontext.MLContext.ExecutionType

All Implemented Interfaces:

Serializable, Comparable<MLContext.ExecutionType>

Enclosing class:

MLContext

public static enum MLContext.ExecutionType
extends Enum<MLContext.ExecutionType>

The different types of execution environments supported by SystemDS. The default execution type is DRIVER_AND_SPARK. DRIVER refers to all operations occurring in the local driver JVM. SPARK refers to all operations occurring on Spark. HADOOP refers to all operations occurring on Hadoop. DRIVER_AND_SPARK refers to operations occurring in the local driver JVM and on Spark when appropriate. DRIVER_AND_HADOOP refers to operations occurring in the local driver JVM and on Hadoop when appropriate.

Method Detail

values

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

Returns:

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

valueOf

public static MLContext.ExecutionType 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
