removeError

public boolean removeError(String poolName)

getType

@NotNull
public String getType()

Specified by:

getType in class HealthStatusReport

Returns:

unique identifier of the problem finder

getDisplayName

@NotNull
public String getDisplayName()

Description copied from class: HealthStatusReport

User presentable name of the problem finder.

Specified by:

getDisplayName in class HealthStatusReport

Returns:

name of the problem finder to show in the user interface.

getCategories

@NotNull
public Collection<ItemCategory> getCategories()

Description copied from class: HealthStatusReport

Problems categories producing by this problem finder. All problems of 'undeclared' categories will be filtered even if they were consumed.

Specified by:

getCategories in class HealthStatusReport

Returns:

Unmodifiable not-empty collection of unique categories producing by this problem finder.

canReportItemsFor

public boolean canReportItemsFor(HealthStatusScope scope)

Description copied from class: HealthStatusReport

Check whether the report can produce any items accepted by the specified scope. HealthStatusReport.report(HealthStatusScope, HealthStatusItemConsumer) will not be called if this method return false. Implementations should not perform any complex calculations, they are expected to quickly analyze HealthStatusScope and return false if it is clear that they can not report any acceptable items. For example, they can return false if they can't produce items with the requested severity (that is accepted by HealthStatusScope.isItemWithSeverityAccepted(ItemSeverity)).

Specified by:

canReportItemsFor in class HealthStatusReport

report

public void report(@NotNull
                   HealthStatusScope scope,
                   @NotNull
                   HealthStatusItemConsumer resultConsumer)

Description copied from class: HealthStatusReport

When called must report all found problems to result consumer according to the received scope. Always called with system privileges (in all permissions mode) so no permission checks are required.

Note that this method can be called quite often, so long-running implementations should return false from HealthStatusReport.canReportItemsFor(HealthStatusScope) if it's clear that they can't produce any items for the requested scope.

Implementations of this method should always return in a reasonable time. For example, long running computations or network calls should not be made in this method, but rather called in some background thread, their result saved to a cache, and then be read from the cache in this method.

Specified by:

report in class HealthStatusReport

Parameters:

scope - health status code

resultConsumer - health status item consumer
