fmt - the codename of the format

Method Detail

tryToRecognize

public void tryToRecognize(java.lang.String line,
                           int linenum,
                           RecognizerList reclist)

tryToRecognize in class Recognizer

Parameters:

line - the line

linenum - the line number

reclist - the list of recognizers

needsMore

public boolean needsMore()

Should we read more lines?

Specified by:

needsMore in class Recognizer

Returns:

true if more lines are needed, false otherwise

canBeSMILES

public static boolean canBeSMILES(java.lang.String s)

Tests whether a string can be SMILES.

Parameters:

s - the input string

Returns:

true if it can be, false if it cannot be SMILES

canBeSMARTS

public static boolean canBeSMARTS(java.lang.String s)

Tests whether a string can be SMARTS.

Parameters:

s - the input string

Returns:

true if it can be, false if it cannot be SMARTS.

isComment

public static boolean isComment(java.lang.String s)
