Method Detail

getName

java.lang.String getName()

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

getKind

StaticSourceFile.SourceKind getKind()

The source kind.

isStrong

default boolean isStrong()

Whether the source kind is STRONG.

isWeak

default boolean isWeak()

Whether the source kind is WEAK.

isExtern

default boolean isExtern()

Whether the source kind is EXTERN.

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:

java.lang.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.
