[Expand] Inherited Methods

From class java.lang.Object Object clone() Creates and returns a copy of this Object. boolean equals( Object o) Compares this instance with the specified object and indicates if they are equal. void finalize() Invoked when the garbage collector has detected that this instance is no longer reachable. final Class<?> getClass() Returns the unique instance of Class that represents this object's class. int hashCode() Returns an integer hash code for this object. final void notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up. final void notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up. String toString() Returns a string containing a concise, human-readable description of this object. final void wait() Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object. final void wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires. final void wait(long millis) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.

Public Methods

public static byte[] getAsciiBytes (String data)

Since: API Level 1

Converts the specified string to byte array of ASCII characters.

Parameters

data	the string to be encoded

Returns

• The string as a byte array.

public static String getAsciiString (byte[] data)

Since: API Level 1

Converts the byte array of ASCII characters to a string. This method is to be used when decoding content of HTTP elements (such as response headers)

Parameters

data	the byte array to be encoded

Returns

• The string representation of the byte array

public static String getAsciiString (byte[] data, int offset, int length)

Since: API Level 1

Converts the byte array of ASCII characters to a string. This method is to be used when decoding content of HTTP elements (such as response headers)

Parameters

data	the byte array to be encoded
offset	the index of the first byte to encode
length	the number of bytes to encode

Returns

• The string representation of the byte array

public static byte[] getBytes (String data, String charset)

Since: API Level 1

Converts the specified string to a byte array. If the charset is not supported the default system charset is used.

Parameters

data	the string to be encoded
charset	the desired character encoding

Returns

• The resulting byte array.

public static String getString (byte[] data, String charset)

Since: API Level 1

Converts the byte array of HTTP content characters to a string. If the specified charset is not supported, default system encoding is used.

Parameters

data	the byte array to be encoded
charset	the desired character encoding

Returns

• The result of the conversion.

public static String getString (byte[] data, int offset, int length, String charset)

Since: API Level 1

Converts the byte array of HTTP content characters to a string. If the specified charset is not supported, default system encoding is used.

Parameters

data	the byte array to be encoded
offset	the index of the first byte to encode
length	the number of bytes to encode
charset	the desired character encoding

Returns

• The result of the conversion.
