Method Detail

setMaxConcurrentFlows

public static void setMaxConcurrentFlows(Map<Object,Object> properties,
                         int numConcurrentFlows)

Method setMaxConcurrentFlows sets the maximum number of Flows that a Cascade can run concurrently.

A value of one (1) will run one Flow at a time. A value of zero (0), the default, disables the restriction.

By default a Cascade will attempt to run all give Flow instances at the same time. But there are occasions where limiting the number for flows helps manages resources.

Parameters:

properties - of type Map

numConcurrentFlows - of type int

cascadeProps

public static CascadeProps cascadeProps()

Creates a new CascadeProps instance.

Returns:

CascadeProps instance

getMaxConcurrentFlows

public int getMaxConcurrentFlows()

setMaxConcurrentFlows

public CascadeProps setMaxConcurrentFlows(int maxConcurrentFlows)

Method setMaxConcurrentFlows sets the maximum number of Flows that a Cascade can run concurrently.

A value of one (1) will run one Flow at a time. A value of zero (0), the default, disables the restriction.

By default a Cascade will attempt to run all give Flow instances at the same time, if eligible. But there are occasions where limiting the number for flows helps manages resources.

Parameters:

maxConcurrentFlows - of type int

addPropertiesTo

protected void addPropertiesTo(Properties properties)
