SimpleSourceFile

public SimpleSourceFile(String name,
                        boolean extern)
Method Detail

getName

public String getName()
Description copied from interface: StaticSourceFile
The name of the file. Must be unique across all files in the compilation.

Specified by:
getName in interface StaticSourceFile

isExtern

public boolean isExtern()
Description copied from interface: StaticSourceFile
Returns whether this is an externs file.

Specified by:
isExtern in interface StaticSourceFile

getColumnOfOffset

public int getColumnOfOffset(int offset)
Description copied from interface: StaticSourceFile
Gets the 0-based column number of the given source offset.

Specified by:
getColumnOfOffset in interface StaticSourceFile
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.

getLineOfOffset

public int getLineOfOffset(int offset)
Description copied from interface: StaticSourceFile
Gets the 1-based line number of the given source offset.

Specified by:
getLineOfOffset in interface StaticSourceFile
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.

getLineOffset

public int getLineOffset(int line)
Description copied from interface: StaticSourceFile
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.

Specified by:
getLineOffset in interface StaticSourceFile
Parameters:
line - the line of the input to get the absolute offset of.
Returns:
the absolute offset of the start of the provided line.

toString

public String toString()
Overrides:
toString in class Object
