Method Detail

getChangeHighlightingDirtyScopeFor

PsiElement getChangeHighlightingDirtyScopeFor(PsiElement changedElement)

Returns:

the psi element (ancestor of the changedElement) which should be re-highlighted, or null if unsure. Examples: - in Java, when the statement has changed, re-highlight the enclosing code block only. - in (hypothetical) framework which stores its annotations in comments, e.g. "// @someAnnotation", when that special comment has changed, re-highlight the whole file. Note: for the performance sake, do not traverse PSI tree upwards here, since this method will be called for the changed element and all its parents anyway. So the parent check is enough, e.g: changedElement.getParent() instanceof PsiCodeBlock
