org.devtools.util
Class MultiProperties  

java.lang.Object
  java.util.Dictionary
      java.util.Hashtable
          java.util.Properties
              org.devtools.util.MultiProperties

All Implemented Interfaces:

java.lang.Cloneable, java.util.Map, java.io.Serializable

---

public class MultiProperties

extends java.util.Properties

Behaves like an ordinary java.util.Properties, except that when it encounters multiple properties of the same name, it concatenates them with the separator string. Properties are written out again similarly.

For example, when MultiProperties loads a properties file containing:

myProp = foo
myProp = bar

The MultiProperties will subsequently contain one property whose name is myProp and whose value is foo:bar. (Assuming that the separator string is ":", which is the default.)

Constructor Detail

MultiProperties

public MultiProperties()

Constructs a new empty MultiProperties with no defaults that will replace existing properties with loaded ones instead of appending them by default.

---

MultiProperties

public MultiProperties(java.util.Properties defaults)

Constructs a new empty MultiProperties with the given defaults.

Method Detail

appendValue

public void appendValue(java.lang.String key,
                        java.lang.String val)

Appends the given value to the existing value for the given key, separating the two with SEP.

---

mergeFrom

public void mergeFrom(java.util.Properties p)

Merges all of the keys from the given Properties into this one, appending the values of any duplicate keys to the existing values.

---

replaceFrom

public void replaceFrom(java.util.Properties p)

Merges all of the keys from the given Properties into this one, replacing the values of any duplicate keys with the new values.

---

getValues

public java.util.Enumeration getValues(java.lang.String key)

Returns an enumeration of all of the values for a given key.

---

load

public void load(java.io.InputStream in)
          throws java.io.IOException

Merges some properties from the given input stream into this MultiProperties. If the InputStream duplicates some existing properties, the existing values will be replaced.

---

load

public void load(java.io.InputStream in,
                 boolean appendOnLoad)
          throws java.io.IOException

Merges some properties from the given input stream into this MultiProperties. If the InputStream duplicates some existing properties and appendOnLoad is true, they will all be appended to the current values of the duplicate properties. If the InputStream duplicates some existing properties and appendOnLoad is false, the existing values will be replaced.

---

writeContents

public void writeContents(java.io.PrintStream out)

Writes a human-readable representation of this MultiProperties to the given print stream.

---

equals

public boolean equals(java.lang.Object o)

---

main

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

---

test

protected static boolean test(java.lang.String[] args)

A testing function
