Method Detail

size

public int size()

getOffsetInfo

@NotNull
public @NotNull OffsetInfo getOffsetInfo(int offset,
                                                  boolean isEndOffset)

Return the range of indices in the sequence of this based offset tracker that correspond to the given offset in the base sequence from which this sequence was derived.

NOTE: indented use is the recover the editing caret position from original text after some text transformation such as formatting, rendering HTML or paragraph wrapping.

Parameters:

offset - offset in base sequence

isEndOffset - if true then offset represents the range [offset, offset) so it is located between character at offset-1 and character at offset if false then offset represents the character at offset and the range [offset, offset+1)

Returns:

information about the offset in this sequence

getSequence

@NotNull
public @NotNull BasedSequence getSequence()

getSegmentOffsetTree

@NotNull
public @NotNull SegmentOffsetTree getSegmentOffsetTree()

toString

public String toString()

Overrides:

toString in class Object

                                                          @NotNull BasedSequence sequence)

Create a based offset tracker for the given sequence

Parameters:

sequence - sequence which to create offset tracker

Returns:

Create a based offset tracker for the given sequence

Parameters:

sequence - sequence which to create offset tracker

segmentOffsetTree - segment offset tree for the sequence

Returns:

based offset tracker
