Enum SingleNodeContainer.MemoryPolicy

java.lang.Object
  java.lang.Enum<SingleNodeContainer.MemoryPolicy>
      org.knime.core.node.workflow.SingleNodeContainer.MemoryPolicy

All Implemented Interfaces:

Serializable, Comparable<SingleNodeContainer.MemoryPolicy>

Enclosing class:

SingleNodeContainer

public static enum SingleNodeContainer.MemoryPolicy
extends Enum<SingleNodeContainer.MemoryPolicy>

Available policy how to handle output data. It might be held in memory or completely on disc. We use an enum here as a boolean may not be sufficient in the future (possibly adding a third option "try to keep in memory").

Enum Constant Summary

CacheInMemory
Hold output in memory.

CacheOnDisc
Buffer on disc.

CacheSmallInMemory
Cache only small tables in memory, i.e.

Method Summary

static SingleNodeContainer.MemoryPolicy	valueOf(String name) Returns the enum constant of this type with the specified name.
static SingleNodeContainer.MemoryPolicy[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

CacheInMemory

public static final SingleNodeContainer.MemoryPolicy CacheInMemory

Hold output in memory.

CacheSmallInMemory

public static final SingleNodeContainer.MemoryPolicy CacheSmallInMemory

Cache only small tables in memory, i.e. with cell count <= DataContainer.MAX_CELLS_IN_MEMORY.

CacheOnDisc

public static final SingleNodeContainer.MemoryPolicy CacheOnDisc

Buffer on disc.

Method Detail

values

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

Returns:

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

valueOf

public static SingleNodeContainer.MemoryPolicy 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
