Method Detail

getInput

public InputStream getInput()
                     throws IOException

Create a new FileInputStream for the input file given in the configuration. The InputStream must be closed by the caller.

Specified by:

getInput in interface CodeData

Returns:

a new FileInputStream for reading the input data.

Throws:

IOException - if the creation of the FileInputStream fails.

getOutput

public OutputStream getOutput()
                       throws IOException

Create a new FileOutputStream for writing the csv output file. If the folder for the output file does not exists then it will be created.

Specified by:

getOutput in interface CodeData

Returns:

a new FileOutputStream for writing the csv data.

Throws:

IOException - if the creation of the FileOutputStream or the folder fails.

getOutputForIdent

public OutputStream getOutputForIdent(CodeType type,
                                      EncodingConfig format,
                                      String ident,
                                      String suffix)

This method may be called from different threads as long as the parameters are different.

Specified by:

getOutputForIdent in interface CodeData

Parameters:

type - the type to write.

format - the encoding format to write.

ident - the ident of the data.

suffix - the suffix of the file to write.
