@Deprecated
public class MembershipAttributes
extends Object
implements DataSerializable, Externalizable

Configuration attributes for defining reliability requirements and behavior for a Region.

MembershipAttributes provides options for configuring a Region to require one or more membership roles to be present in the system for reliable access to the Region. Each Role is a user defined string name, such as Producer or Backup or FooProducer.

The LossAction defines the behavior when one or more required roles are missing.

The ResumptionAction specifies the action to be taken when reliability resumes.

MembershipAttributes have no effect unless one or more required roles are specified. These attributes are immutable after the Region has been created.

Constructor Detail

MembershipAttributes

public MembershipAttributes()

Deprecated.

Creates a new MembershipAttributes with the default configuration of no required roles.

MembershipAttributes

public MembershipAttributes(String[] requiredRoles)

Deprecated.

Creates a new MembershipAttributes with the specified required role names. Reliability policy will default to NO_ACCESS, and resumption action will default to REINITIALIZE.

Parameters:

requiredRoles - array of role names required by this process for reliable access to the region

Throws:

IllegalArgumentException - if no requiredRoles are specified

MembershipAttributes

public MembershipAttributes(String[] requiredRoles,
                            LossAction lossAction,
                            ResumptionAction resumptionAction)

Deprecated.

Creates a new MembershipAttributes with the specified required role names, reliability policy, and resumption action.

Parameters:

requiredRoles - array of role names required by this process for reliable access to the region

lossAction - the configuration defining how this process behaves when there are missing required roles

resumptionAction - the action to take when missing required roles return to the system

Throws:

IllegalArgumentException - if the resumptionAction is incompatible with the lossAction or if no requiredRoles are specified

Method Detail

getRequiredRoles

public Set<Role> getRequiredRoles()

Deprecated.

Returns the set of Roles that are required for the reliability of this region.

Returns:

the set of Roles that are required for the reliability of this region

hasRequiredRoles

public boolean hasRequiredRoles()

Deprecated.

Returns true if there are one or more required roles specified.

Returns:

whether there are one or more required roles specified

getLossAction

public LossAction getLossAction()

Deprecated.

Returns the reliability policy that describes behavior if any required roles are missing.

Returns:

the reliability policy that describes behavior if any required roles are missing

getResumptionAction

public ResumptionAction getResumptionAction()

Deprecated.

Returns the resumption action that describes behavior when missing required roles return to the system

Returns:

the resumption action that describes behavior when missing required roles return to the system

equals

public boolean equals(Object other)

Deprecated.

Indicates whether some other object is "equal to" this one.

Overrides:

equals in class Object

Parameters:

other - the reference object with which to compare.

Returns:

true if this object is the same as the obj argument; false otherwise.

hashCode

public int hashCode()

Deprecated.

Returns a hash code for the object. This method is supported for the benefit of hashtables such as those provided by java.util.Hashtable.

Overrides:

hashCode in class Object

Returns:

the integer 0 if description is null; otherwise a unique integer.

toString

public String toString()

Deprecated.

Returns a string representation of the object.

Overrides:

toString in class Object

Returns:

a string representation of the object

toData

public void toData(DataOutput out)
            throws IOException

Deprecated.

Description copied from interface: DataSerializable

Writes the state of this object as primitive data to the given DataOutput.

Since 5.7 it is possible for any method call to the specified DataOutput to throw GemFireRethrowable. It should not be caught by user code. If it is it must be rethrown.

Specified by:

toData in interface DataSerializable

Parameters:

out - the DataOutput to write to

Throws:

IOException - A problem occurs while writing to out

fromData

public void fromData(DataInput in)
              throws IOException,
                     ClassNotFoundException

Deprecated.

Description copied from interface: DataSerializable

Reads the state of this object as primitive data from the given DataInput.

Specified by:

fromData in interface DataSerializable

Parameters:

in - the DataInput to read from

Throws:

IOException - A problem occurs while reading from in

ClassNotFoundException - A class could not be loaded while reading from in

writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException

Deprecated.

Specified by:

writeExternal in interface Externalizable

Throws:

IOException

readExternal

public void readExternal(ObjectInput in)
                  throws IOException,
