public class TempFileGenerator

extends java.lang.Object

Create unique filenames and/or files. User can supply a name base and/or a prefix, and also a directory. The generated filename will be dir[\]base_[randomNumbers]suffix If dir is not specified, it will be c:\temp if that is a valid directory, otherwise it'll be an empty string, causing java to use the current directory. So a possible filename, given dir="c:\temp", base="blah", and suffix=".xxx" would be something like "c:\temp\blah_345953829.xxx". If the given dir name doesn't end with the local platform's file separator character, then the separator char will be appended. Thus after a call fileGen.setDirectory("c:"), fileGen.getDirectory() will return "c:\".

Constructor Detail

TempFileGenerator

public TempFileGenerator(java.lang.String nameBase,
                         java.lang.String nameSuffix)

Create a new TempFileGenerator having base nameBase and suffix nameSuffix.

TempFileGenerator

public TempFileGenerator(java.lang.String dir,
                         java.lang.String nameBase,
                         java.lang.String nameSuffix)

Create a new TempFileGenerator having base nameBase, suffix nameSuffix, and directory dir.

Method Detail

generateFile

public java.io.File generateFile()

Create a unique filename, create a file, and return the File object.

generateFile

public java.io.File generateFile(java.lang.String midName)

Create a filename, create a file, and return the File object. Note that explicitly passing midName bypasses the random-name-generation mechanism, so the returned filename is fuly predicatable (dir+base+mid+suffix).

generateFileName

public java.lang.String generateFileName()

Return a filename that's guaranteed not to exist.

generateFileName

public java.lang.String generateFileName(java.lang.String midName)

Generate a non-random filename (dir+base+mid+suffix)

getDirectory

public java.lang.String getDirectory()

getNameBase

public java.lang.String getNameBase()

getNameSuffix

public java.lang.String getNameSuffix()

main

public static void main(java.lang.String[] args)

Main method to test the class somewhat.

setDirectory

public void setDirectory(java.lang.String dir)

setNameBase

public void setNameBase(java.lang.String nameBase)

setNameSuffix

public void setNameSuffix(java.lang.String nameSuff)
