OffsetMapping

public interface OffsetMapping

Provides bidirectional offset mapping between original and transformed text.

Functions

originalToTransformed

public fun originalToTransformed(offset: Int): Int

Convert offset in original text into the offset in transformed text.

This function must be a monotonically non-decreasing function. In other words, if a cursor advances in the original text, the cursor in the transformed text must advance or stay there.

Parameters

Return

offset in transformed text

transformedToOriginal

public fun transformedToOriginal(offset: Int): Int

Convert offset in transformed text into the offset in original text.

This function must be a monotonically non-decreasing function. In other words, if a cursor advances in the transformed text, the cursor in the original text must advance or stay there.

Parameters

Return

offset in original text
