Method Summary

Methods

Modifier and Type	Method and Description
int	getColumnOfOffset(int offset) Gets the 0-based column number of the given source offset.
int	getLineOffset(int lineNumber) Returns the offset of the given line number relative to the file start.
int	getLineOfOffset(int offset) Gets the 1-based line number of the given source offset.
String	getName() The name of the file.
boolean	isExtern() Returns whether this is an externs file.

Method Detail

getName

String getName()

The name of the file. Must be unique across all files in the compilation.

isExtern

boolean isExtern()

Returns whether this is an externs file.

getLineOffset

int getLineOffset(int lineNumber)

Returns the offset of the given line number relative to the file start. Line number should be 1-based. If the source file doesn't have line information, it should return Integer.MIN_VALUE. The negative offsets will make it more obvious what happened.

Parameters:

lineNumber - the line of the input to get the absolute offset of.

Returns:

the absolute offset of the start of the provided line.

Throws:

IllegalArgumentException - if lineno is less than 1 or greater than the number of lines in the source.

getLineOfOffset

int getLineOfOffset(int offset)

Gets the 1-based line number of the given source offset.

Parameters:

offset - An absolute file offset.

Returns:

The 1-based line number of that offset. The behavior is undefined if this offset does not exist in the source file.

getColumnOfOffset

int getColumnOfOffset(int offset)

Gets the 0-based column number of the given source offset.

Parameters:

offset - An absolute file offset.

Returns:

The 0-based column number of that offset. The behavior is undefined if this offset does not exist in the source file.
