Method Detail

createCachedValue

public <T> CachedValue<T> createCachedValue(CachedValueProvider<T> provider,
                                            boolean trackValue)

Description copied from class: CachedValuesManager

Creates new CachedValue instance with given provider. If the return value is marked as trackable, it's treated as yet another dependency and must comply its specification. See CachedValueProvider.Result.getDependencyItems() for the details.

Specified by:

createCachedValue in class CachedValuesManager

Parameters:

provider - computes values.

trackValue - if value tracking is required. T should be trackable in this case.

Returns:

new CachedValue instance.

createParameterizedCachedValue

public <T,P> ParameterizedCachedValue<T,P> createParameterizedCachedValue(ParameterizedCachedValueProvider<T,P> provider,
                                                                          boolean trackValue)

Specified by:

createParameterizedCachedValue in class CachedValuesManager

getCachedValue

public <T> T getCachedValue(UserDataHolder dataHolder,
                            Key<CachedValue<T>> key,
                            CachedValueProvider<T> provider,
                            boolean trackValue)

Description copied from class: CachedValuesManager

Utility method storing created cached values in a UserDataHolder. The passed cached value provider may only depend on the passed user data holder and longer-living system state (e.g. project/application components/services), see CachedValue documentation for more details.

Specified by:

getCachedValue in class CachedValuesManager

Parameters:

dataHolder - holder to store the cached value, e.g. a PsiElement.

key - key to store the cached value.

provider - provider creating the cached value.

trackValue - if value tracking is required (T should be trackable in that case). See CachedValuesManager.createCachedValue(CachedValueProvider, boolean) for more details.

Returns:

up-to-date value.

trackKeyHolder

protected void trackKeyHolder(UserDataHolder dataHolder,
                              Key<?> key)

Specified by:

trackKeyHolder in class CachedValuesManager

clearCachedValues
