public virtual void TextStorageEditedRangeChangeInLengthInvalidatedRange(
	NSTextStorage aTextStorage,
	NSUInteger mask,

)

Public Overridable Sub TextStorageEditedRangeChangeInLengthInvalidatedRange ( _
	aTextStorage As NSTextStorage, _
	mask As NSUInteger, _
	newCharRange As NSRange, _
	delta As NSInteger, _
	invalidatedCharRange As NSRange _
)

public:
virtual void TextStorageEditedRangeChangeInLengthInvalidatedRange(
	NSTextStorage^ aTextStorage, 
	NSUInteger mask, 
	NSRange newCharRange, 
	NSInteger delta, 
	NSRange invalidatedCharRange
)

Parameters

aTextStorage (NSTextStorage): The text storage whose information is invalidated.

mask (NSUInteger): Specifies the nature of the changes. Its value is made by combining with the C bitwise OR operator the constants described in “Change notifications” in NSTextStorage (NSTextStorageEditedAttributes and NSTextStorageEditedCharacters).

newCharRange (NSRange): Indicates the extent of characters resulting from the edits.

delta (NSInteger): If the NSTextStorageEditedCharacters bit of mask is set, gives the number of characters added to or removed from the original range (otherwise its value is irrelevant).

invalidatedCharRange (NSRange): Represents the range of characters affected after attributes have been fixed. Is either equal to newCharRange or larger. For example, deleting a paragraph separator character invalidates the layout information for all characters in the paragraphs that precede and follow the separator.
