Functions

originalToTransformed

public fun originalToTransformed(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.
