Constructor Detail

PsiModificationTrackerImpl

public PsiModificationTrackerImpl(Project project)

Method Detail

incCounter

public void incCounter()

incOutOfCodeBlockModificationCounter

public void incOutOfCodeBlockModificationCounter()

treeChanged

public void treeChanged(PsiTreeChangeEventImpl event)

Specified by:

treeChanged in interface PsiTreeChangePreprocessor

canAffectPsi

public static boolean canAffectPsi(PsiTreeChangeEventImpl event)

getModificationCount

public long getModificationCount()

Description copied from interface: PsiModificationTracker

Tracks any PSI modification.

Specified by:

getModificationCount in interface ModificationTracker

Specified by:

getModificationCount in interface PsiModificationTracker

Returns:

current counter value. Increased whenever any physical PSI is changed.

getOutOfCodeBlockModificationCount

public long getOutOfCodeBlockModificationCount()

Specified by:

getOutOfCodeBlockModificationCount in interface PsiModificationTracker

Returns:

Same as PsiModificationTracker.getJavaStructureModificationCount(), but also includes changes in non-Java files, e.g. XML. Rarely needed.

getJavaStructureModificationCount

public long getJavaStructureModificationCount()

Description copied from interface: PsiModificationTracker

Tracks structural Java modifications, i.e. the ones on class/method/field/file level. Modifications inside method bodies are not tracked. Useful to work with resolve caches that only depend on Java structure, and not the method code.

Specified by:

getJavaStructureModificationCount in interface PsiModificationTracker

Returns:

current counter value. Increased whenever any physical PSI in Java structure is changed.

getOutOfCodeBlockModificationTracker

public ModificationTracker getOutOfCodeBlockModificationTracker()

Specified by:

getOutOfCodeBlockModificationTracker in interface PsiModificationTracker

Returns:

an object returning PsiModificationTracker.getOutOfCodeBlockModificationCount()

getJavaStructureModificationTracker

public ModificationTracker getJavaStructureModificationTracker()

Specified by:

getJavaStructureModificationTracker in interface PsiModificationTracker

Returns:

an object returning PsiModificationTracker.getJavaStructureModificationCount()

incLanguageModificationCount

public void incLanguageModificationCount(Language language)

forLanguage

public ModificationTracker forLanguage(Language language)

forLanguages

public ModificationTracker forLanguages(Condition<? super Language> condition)
