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

QuorumRule

public 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

QuorumRule

public QuorumRule(int nRuleMask,
                  int nThreshold,
                  float flThresholdPct)

Construct a state with the specified threshold and numeric representation.

Parameters:

nRuleMask - numeric representation of the state

nThreshold - the size threshold of the state

flThresholdPct - the size of threshold of the state in percentage

Method Detail

compareTo

public int compareTo(ConfigurableQuorumPolicy.MembershipQuorumPolicy.QuorumRule that)

Compare this Rule to another one based on the threshold.

Specified by:

compareTo in interface Comparable<ConfigurableQuorumPolicy.MembershipQuorumPolicy.QuorumRule>

toString

public String toString()

Overrides:

toString in class Object

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

getThresholdFactor

protected float getThresholdFactor()

Return the percentage threshold for this rule.

Returns:

the percentage threshold for this rule

setThresholdFactor

protected void setThresholdFactor(float flThreshold)

Set the percentage threshold for this rule.

Parameters:

flThreshold - the percentage threshold for this rule
