Introduction

In this page you can find the example usage for java.io ObjectOutput writeUTF.

Prototype

void writeUTF(String s) throws IOException;

Source Link

Document

Writes two bytes of length information to the output stream, followed by the modified UTF-8 representation of every character in the string s.

Usage

From source file:org.apache.tapestry.engine.BaseEngine.java

/**
 *  Writes the engine's persistent state; this is simply the list of active page
 *  names.  For efficiency, this is written as a count followed by each name
 *  as a UTF String.// ww w .  ja v  a  2  s  .co m
 * 
 **/

public void writeExternal(ObjectOutput out) throws IOException {
    super.writeExternal(out);

    if (Tapestry.isEmpty(_activePageNames)) {
        out.writeInt(0);
        return;
    }

    int count = _activePageNames.size();

    out.writeInt(count);

    Iterator i = _activePageNames.iterator();

    while (i.hasNext()) {
        String name = (String) i.next();

        out.writeUTF(name);
    }
