Class SchedulerContext

java.lang.Object
  org.quartz.utils.DirtyFlagMap
      org.quartz.SchedulerContext

All Implemented Interfaces:

Cloneable, Map, Serializable

public class SchedulerContext

extends DirtyFlagMap

implements Serializable

Holds context/environment data that can be made available to Jobs as they are executed. This feature is much like the ServletContext feature when working with J2EE servlets.

Constructor Detail

SchedulerContext

public SchedulerContext()

Create an empty JobDataMap.

SchedulerContext

public SchedulerContext(Map map)

Create a JobDataMap with the given data.

Method Detail

setAllowsTransientData

public void setAllowsTransientData(boolean allowsTransientData)

Tell the SchedulerContext that it should allow non- Serializable data.

Future versions of Quartz may make distinctions on how it propogates data in the SchedulerContext between instances of proxies to a single scheduler instance - i.e. if Quartz is being used via RMI.

getAllowsTransientData

public boolean getAllowsTransientData()

containsTransientData

public boolean containsTransientData()

removeTransientData

public void removeTransientData()

Nulls-out any data values that are non-Serializable.

putAll

public void putAll(Map map)

Adds the name-value pairs in the given Map to the SchedulerContext.

All keys must be Strings.

Specified by:

putAll in interface Map

Overrides:

putAll in class DirtyFlagMap

put

public void put(String key,
                int value)

Adds the given int value to the SchedulerContext.

put

public void put(String key,
                long value)

Adds the given long value to the SchedulerContext.

put

public void put(String key,
                float value)

Adds the given float value to the SchedulerContext.

put

public void put(String key,
                double value)

Adds the given double value to the SchedulerContext.

put

public void put(String key,
                boolean value)

Adds the given boolean value to the SchedulerContext.

put

public void put(String key,
                char value)

Adds the given char value to the SchedulerContext.

put

public void put(String key,
                String value)

Adds the given String value to the SchedulerContext.

put

public Object put(Object key,
                  Object value)

Adds the given Object value to the SchedulerContext.

Specified by:

put in interface Map

Overrides:

put in class DirtyFlagMap
