Method Detail

getCacheId

public String getCacheId()

Description copied from interface: EnforcerRule

If the rule is to be cached, this id is used as part of the key. This can allow rules to take parameters that allow multiple results of the same rule to be cached.

Returns:

id to be used by the enforcer to determine uniqueness of cache results. The ids only need to be unique within a given rule implementation as the full key will be [classname]-[id]

isCacheable

public boolean isCacheable()

Description copied from interface: EnforcerRule

This method tells the enforcer if the rule results may be cached. If the result is true, the results will be remembered for future executions in the same build (ie children). Subsequent iterations of the rule will be queried to see if they are also cacheable. This will allow the rule to be uncached further down the tree if needed.

Returns:

true if rule is cacheable

isResultValid

public boolean isResultValid(EnforcerRule cachedRule)

Description copied from interface: EnforcerRule

Checks if cached result is valid.

Parameters:

cachedRule - the last cached instance of the rule. This is to be used by the rule to potentially determine if the results are still valid (ie if the configuration has been overridden)

Returns:

true if the stored results are valid for the same id.
