Method Detail

getTokenType

public TokenType getTokenType()

getTokenStart

public int getTokenStart()

getTokenEnd

public int getTokenEnd()

preserveMaskedOutSpace

protected void preserveMaskedOutSpace(StringBuilder result,
                                      CharSequence source)

See preserveMaskedOutSpace(StringBuilder, CharSequence, int, int)

preserveMaskedOutSpace

protected void preserveMaskedOutSpace(StringBuilder result,
                                      CharSequence source,
                                      int tokenStart,
                                      int tokenEnd)

Replaces preprocessor directives and masked out source with whitespace. Retains newline characters.

Note, a more efficient approach would involve only preserving newline chars for debug purposes and omitting masked out source. However, since javac determines compile error line numbers from the error offset into the original file, we must preserve the full length and structure of the original source.

Parameters:

result - The resulting preprocessed source.

source - The original source.
