public interface TextChange

Provides generic contract for object encapsulating information about single unit of text change.

Implementations of this interface are not obliged to be thread-safe.

Method Summary

Modifier and Type	Method and Description
char []	getChars() Allows to get change text as a char array.
int	getEnd()
int	getStart()
java.lang.CharSequence	getText() Allows to retrieve text that is directly affected by the change encapsulated by the current object.

Method Detail

getStart

int getStart()

Returns:

start index (inclusive) of text range affected by the change encapsulated at the current object

getEnd

int getEnd()

Returns:

end index (exclusive) of text range affected by the change encapsulated at the current object

getText

java.lang.CharSequence getText()

Allows to retrieve text that is directly affected by the change encapsulated by the current object.

Returns:

text related to the change encapsulated by the current object

getChars

char [] getChars()

Allows to get change text as a char array. Note that it's not guaranteed that change text directly maps to the returned char array, i.e. change to array content is not obeyed to be reflected in getText() result.

Generally speaking, this method is introduced just as a step toward existing high-performance services that work in terms of char arrays. Resulting array is instantiated on-demand via CharArrayUtil.fromSequence(CharSequence), hence, it doesn't hit memory if, for example, CharSequenceBackedByArray is used as initial change text.

Returns:

stored change text as a char array
