startScope
Label startScope()Returns the start of the instruction range.- Returns:
- the start of the instruction range
-
endScope
Label endScope()Returns the end of the instruction range.- Returns:
- the end of the instruction range

characterRangeStart
int characterRangeStart()Returns the encoded start of the character range region (inclusive). The value is constructed from the line_number/column_number pair as given byline_number << 10 + column_number
, where the source file is viewed as an array of (possibly multi-byte) characters.- Returns:
- the encoded start of the character range region (inclusive)
-
characterRangeEnd
int characterRangeEnd()Returns the encoded end of the character range region (exclusive).. The value is constructed from the line_number/column_number pair as given byline_number << 10 + column_number
, where the source file is viewed as an array of (possibly multi-byte) characters.- Returns:
- the encoded end of the character range region (exclusive)
