SimpleSourceFile

public SimpleSourceFile(java.lang.String name,
                        boolean extern)

Method Detail

getName

public java.lang.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 java.lang.String toString()

Overrides:

toString in class java.lang.Object
