Class CodeGenerator

java.lang.Object

org.sw4j.tool.barcode.random.generator.CodeGenerator

public class CodeGenerator
extends Object

This class takes the configuration (from the package org.sw4j.tool.barcode.random.config) and uses this configuration to generate encoded random numbers and barcodes.

This class is not thread safe.

Constructor Detail

CodeGenerator

public CodeGenerator(GenerationConfig config,
                     CodeData codeData)

The constructor for a new CodeGenerator. The code generator is initialized with the random configuration and a factory for the input and output streams.

The code generator is initialized with a SecureRandom random number generator.

Parameters:

config - the random number configuration.

codeData - the factories for the input and output streams.

CodeGenerator

public CodeGenerator(GenerationConfig config,
                     CodeData codeData,
                     Random random)

The constructor for a new CodeGenerator. The code generator is initialized with the random configuration and a factory for the input and output streams.

The code generator uses the random number generator supplied during construction.

Attention: if you do not know the security issues involved with using your own random number generator please use the constructor #CodeGenerator(RandomConfig,CodeData) which creates a secure random number generator for you.

Parameters:

config - the random number configuration.

codeData - the factories for the input and output streams.

random - the random number generator to use.

Method Detail

createCodes

public void createCodes()
                 throws IOException

Create the random numbers (and encoded representations) for the idents and writes the codes to the output csv file.

Throws:

IOException - if the reading or writing of the data fails.

IllegalArgumentException - if a duplicate ident is found in the input.

convertCodes

public Set<IdentValue> convertCodes(Map<String,String> inputValues,
                                    EncodingConfig encoding,
                                    Set<EncodingConfig> encodings)

Create the encoded representation for all inputValues.

This method is thread safe.

Parameters:

inputValues - the inputValues (idents) for which the random numbers should be created.

encoding - the encoding of the source value.

encodings - the encodings that should be created for the random numbers.

Returns:

a set of RandomIdent instances with the random numbers and the encoded random numbers.

createCodes

public Set<IdentValue> createCodes(Collection<String> inputValues,
                                   Set<EncodingConfig> encodings)

Create random values for all inputValues. Additionally the encoded representation for the random values are created.

This method is thread safe.

Parameters:

inputValues - the inputValues (idents) for which the random numbers should be created.

encodings - the encodings that should be created for the random numbers.

Returns:

a set of RandomIdent instances with the random numbers and the encoded random numbers.
