Object

gudusoft.gsqlparser.dlineage.dynamicsql.SqlFragment.SourcePiece

Enclosing class:

SqlFragment

public static final class SqlFragment.SourcePiece
extends Object

length characters of a LITERAL's text, from textStart, read from one string literal token of the analyzed source (Mantis 4851): where each sits there, so that what GSP analyzes inside the string reports positions in the source. '' is one character of the text and two of the source; the token keeps its quotes, a one-letter prefix such as N, and its line breaks.

static SqlFragment.SourcePiece	of(TSourceToken token, String decoded) The piece of string literal token token whose content decodes to decoded: null unless the token is a single-quoted literal (with at most a one-letter prefix) whose content, '' read as one quote, is exactly decoded.
