Pos

public Pos(String file,
 int startLine,
 int startColumn,
 int endLine,
 int endColumn)

Creates a Pos.

Method Details

of

public static Pos of(String ml,
 String file,
 int startOffset,
 int endOffset)

Creates a Pos from two offsets.

split

public static Pair<@NonNull String,@NonNull Pos> split(String s,
 char delimiter,
 String file)

Creates a Pos from a filename and a string with a delimiter character. The delimiter must occur exactly twice in the string.

describeTo

public StringBuilder describeTo(StringBuilder buf)

sum

public static Pos sum(Iterable<Pos> poses)

Combines an iterable of parser positions to create a position which spans from the beginning of the first to the end of the last.

sum

public static <E> Pos sum(Iterable<E> elements,
 Function<E,Pos> fn)

sum

public static Pos sum(List<? extends AstNode> nodes)

sum_

private static Pos sum_(List<Pos> positions)

Combines a list of parser positions to create a position which spans from the beginning of the first to the end of the last.

sum

private static Pos sum(Iterable<Pos> poses,
 int line,
 int column,
 int endLine,
 int endColumn)

Computes the parser position which is the sum of an array of parser positions and of a parser position represented by (line, column, endLine, endColumn).

Parameters:

poses - Array of parser positions

line - Start line

column - Start column

endLine - End line

endColumn - End column

Returns:

Sum of parser positions

plus

public Pos plus(Pos pos)

plusAll

public Pos plusAll(Iterable<Pos> poses)

plusAll

public Pos plusAll(@Nonnull
 List<? extends AstNode> nodes)

lineCol

private static org.apache.calcite.util.mapping.IntPair lineCol(String s,
 int offset)

Returns the 1-based line.
