Constructor Detail

MolInputStream

public MolInputStream(InputStream is)
               throws IOException

Create a molecule input stream from an ordinary one, and determine the format.

Parameters:

is - the original input stream

Throws:

IOException - error occurred while trying to guess the file format

MolInputStream

public MolInputStream(InputStream is,
                      String fmt)
               throws IOException

Create a molecule input stream from an ordinary one, If null is specified as the fmt argument, then the file format is determined automatically. If "mol" or "csmol" is specified, then the file format is determined from the first line as "mol", "csmol", "rxn", "csrxn", "rgf" or "csrgf".

Parameters:

is - the original input stream

fmt - the input file format or null

Throws:

IOException - error occurred while trying to guess the file format

MolInputStream

public MolInputStream(InputStream is,
                      String fmt,
                      String enc)
               throws IOException

Create a molecule input stream from an ordinary one, If null is specified as the fmt argument, then the file format is determined automatically. If "mol" or "csmol" is specified, then the file format is determined from the first line as "mol", "csmol", "rxn", "csrxn", "rgf" or "csrgf".

Parameters:

is - the original input stream

fmt - the input file format or null

enc - the input encoding or null

Throws:

IOException - error occurred while trying to guess the file format

MolInputStream

public MolInputStream(InputStream is,
                      String fmt,
                      String enc,
                      String path)
               throws IOException

Create a molecule input stream from an ordinary one, If null is specified as the fmt argument, then the file format is determined automatically. If "mol" or "csmol" is specified, then the file format is determined from the first line as "mol", "csmol", "rxn", "csrxn", "rgf" or "csrgf". If the file format cannot be determined from the contents and the file name is not null, then the file extension is used to guess the format.

Parameters:

is - the original input stream

fmt - the input file format or null

enc - the input encoding or null

path - the file path (it can also be an URL) or null

Throws:

IOException - error occurred while trying to guess the file format
