getLineOffsets

public com.google.common.collect.ImmutableList<java.lang.Integer> getLineOffsets()

Get the code point offsets (NOT code unit offsets) for new line characters '\n' within the source expression text.

NOTE: The indices point to the index just after the '\n' not the index of '\n' itself.
