Enclosing class:

ConfigurableQuorumPolicy.MembershipQuorumPolicy

public static class ConfigurableQuorumPolicy.MembershipQuorumPolicy.QuorumRule

extends java.lang.Object

A quorum rule defines a set of allowable actions beyond the rule's threshold size.

Field Summary

protected static ConfigurableQuorumPolicy.MembershipQuorumPolicy.QuorumRule	ALL_ALLOWED A QuorumRule that permits all actions.
protected static ConfigurableQuorumPolicy.MembershipQuorumPolicy.QuorumRule	NONE_ALLOWED A QuorumRule that rejects all actions.

Constructor Summary

ConfigurableQuorumPolicy.MembershipQuorumPolicy.QuorumRule(int nRuleMask, int nThreshold)
Construct a state with the specified threshold and numeric representation.

Method Summary

protected boolean	contains(int nMask) Return true if the current rule contains the specified action mask.
protected int	getRuleMask() Return the numeric representation of the actions allowed by this rule.
protected int	getThreshold() Return the size threshold for this rule.
protected void	setRuleMask(int nRuleMask) Set the numeric representation of the actions allowed by this rule.
protected void	setThreshold(int nThreshold) Set the size threshold for this rule.
java.lang.String	toString()
protected ConfigurableQuorumPolicy.MembershipQuorumPolicy.QuorumRule	union(ConfigurableQuorumPolicy.MembershipQuorumPolicy.QuorumRule rule) Return a quorum rule composed from this and the specified rule that reflects the "union" of the two rules.

Field Detail

NONE_ALLOWED

protected static final ConfigurableQuorumPolicy.MembershipQuorumPolicy.QuorumRule NONE_ALLOWED

A QuorumRule that rejects all actions.

ALL_ALLOWED

protected static final ConfigurableQuorumPolicy.MembershipQuorumPolicy.QuorumRule ALL_ALLOWED

A QuorumRule that permits all actions.

Constructor Detail

ConfigurableQuorumPolicy.MembershipQuorumPolicy.QuorumRule

public ConfigurableQuorumPolicy.MembershipQuorumPolicy.QuorumRule(int nRuleMask,
                                                                  int nThreshold)

Construct a state with the specified threshold and numeric representation.

Parameters:

nRuleMask - numeric representation of the state

nThreshold - the size threshold of the state

Method Detail

toString

public java.lang.String toString()

contains

protected boolean contains(int nMask)

Return true if the current rule contains the specified action mask.

Parameters:

nMask - the action bitmask to test for

Returns:

true if the current rule contains the specified action mask

union

protected ConfigurableQuorumPolicy.MembershipQuorumPolicy.QuorumRule union(ConfigurableQuorumPolicy.MembershipQuorumPolicy.QuorumRule rule)

Return a quorum rule composed from this and the specified rule that reflects the "union" of the two rules. The union of two rules A and B requires a membership threshold that is max(A.getThreshold(), A.getThreshold()) and allows all actions allowed by A or B.

Parameters:

rule - the rule to compute the union of this with

Returns:

a quorum rule representing the union with the specified rule

getRuleMask

protected int getRuleMask()

Return the numeric representation of the actions allowed by this rule.

Returns:

the numeric representation of this rule

setRuleMask

protected void setRuleMask(int nRuleMask)

Set the numeric representation of the actions allowed by this rule.

Parameters:

nRuleMask - the numeric representation of this rule

getThreshold

protected int getThreshold()

Return the size threshold for this rule.

Returns:

the size threshold for this rule

setThreshold

protected void setThreshold(int nThreshold)

Set the size threshold for this rule.

Parameters:

nThreshold - the size threshold for this rule
