Examples with FileWriter java.io.FileWriter used on opensource projects

Example 1 with FileWriter

use of java.io.FileWriter in project camel by apache.

the class FileConsumerBeginRenameStrategyTest method testRenameFileExists.

public void testRenameFileExists() throws Exception {
    // create a file in inprogress to let there be a duplicate file
    File file = new File("target/inprogress");
    file.mkdirs();
    FileWriter fw = new FileWriter("target/inprogress/london.txt");
    try {
        fw.write("I was there once in London");
        fw.flush();
    } finally {
        fw.close();
    }
    MockEndpoint mock = getMockEndpoint("mock:report");
    mock.expectedBodiesReceived("Hello London");
    template.sendBodyAndHeader("file:target/reports", "Hello London", Exchange.FILE_NAME, "london.txt");
    mock.assertIsSatisfied();
}

Example 2 with FileWriter

use of java.io.FileWriter in project camel by apache.

the class FileConsumerCommitRenameStrategyTest method testRenameFileExists.

public void testRenameFileExists() throws Exception {
    // create a file in done to let there be a duplicate file
    File file = new File("target/done");
    file.mkdirs();
    FileWriter fw = new FileWriter("target/done/london.txt");
    try {
        fw.write("I was there once in London");
        fw.flush();
    } finally {
        fw.close();
    }
    MockEndpoint mock = getMockEndpoint("mock:report");
    mock.expectedBodiesReceived("Hello London");
    template.sendBodyAndHeader("file:target/reports", "Hello London", Exchange.FILE_NAME, "london.txt");
    mock.assertIsSatisfied();
    oneExchangeDone.matchesMockWaitTime();
    // content of file should be Hello London
    String content = IOConverter.toString(new File("target/done/london.txt"), null);
    assertEquals("The file should have been renamed replacing any existing files", "Hello London", content);
}

Example 3 with FileWriter

use of java.io.FileWriter in project camel by apache.

the class S3ComponentFileTest method setup.

@Before
public void setup() throws Exception {
    super.setUp();
    testFile = FileUtil.createTempFile("test", "file");
    FileWriter writer = new FileWriter(testFile);
    writer.write("This is my bucket content.");
    writer.close();
}

Example 4 with FileWriter

use of java.io.FileWriter in project groovy by apache.

the class DomToGroovy method main.

public static void main(String[] args) {
    if (args.length < 1) {
        System.out.println("Usage: DomToGroovy infilename [outfilename]");
        System.exit(1);
    }
    Document document = null;
    try {
        document = parse(args[0]);
    } catch (Exception e) {
        System.out.println("Unable to parse input file '" + args[0] + "': " + e.getMessage());
        System.exit(1);
    }
    PrintWriter writer = null;
    if (args.length < 2) {
        writer = new PrintWriter(System.out);
    } else {
        try {
            writer = new PrintWriter(new FileWriter(new File(args[1])));
        } catch (IOException e) {
            System.out.println("Unable to create output file '" + args[1] + "': " + e.getMessage());
            System.exit(1);
        }
    }
    DomToGroovy converter = new DomToGroovy(writer);
    converter.out.incrementIndent();
    writer.println("#!/bin/groovy");
    writer.println();
    writer.println("// generated from " + args[0]);
    writer.println("System.out << new groovy.xml.StreamingMarkupBuilder().bind {");
    converter.print(document);
    writer.println("}");
    writer.close();
}

Example 5 with FileWriter

use of java.io.FileWriter in project groovy by apache.

the class CompilerPerformanceTest method main.

public static void main(String[] args) throws Exception {
    List<File> sources = new ArrayList<>();
    List<URL> classpath = new ArrayList<>();
    boolean isCp = false;
    for (String arg : args) {
        if ("-cp".equals(arg)) {
            isCp = true;
        } else if (isCp) {
            classpath.add(new File(arg).toURI().toURL());
        } else {
            sources.add(new File(arg));
        }
    }
    ScriptCompilationExecuter executer = new ScriptCompilationExecuter(sources.toArray(new File[sources.size()]), classpath);
    System.out.println("Using Groovy " + GROOVY_VERSION);
    DescriptiveStatistics stats = new DescriptiveStatistics();
    for (int i = 0; i < WARMUP + REPEAT; i++) {
        if (i < WARMUP) {
            System.out.println("Warmup #" + (i + 1));
        } else {
            System.out.println("Round #" + (i - WARMUP));
        }
        long dur = executer.execute();
        System.gc();
        System.out.printf("Compile time = %dms%n", dur);
        if (i >= WARMUP) {
            stats.addValue((double) dur);
