Class CompactChar

java.lang.Object

com.devexperts.qd.util.CompactChar

Deprecated.

Use IOUtil class instead.

public class CompactChar
extends Object

The CompactChar utility class provides algorithms for compact serialization of characters and strings. It uses CESU-8 format (the format close to UTF-8 but with special handling of surrogate characters). This is generally the same format as used by standard Java I/O streams, though Java uses modified CESU-8 (Java represents character with code 0 using 2-byte encoding, not 1-byte as required). When encoding character sequences, the CompactChar uses CompactInt to encode character sequence length first, then serializes characters themselves. The value -1 for length is used as a marker to distinguish 'null' sequence from empty sequence. See CESU-8 for format basics.

Note: this class is deprecated and is replaced by IOUtil class. See IOUtil class, section UTF APU, and individual methods for documentation.

Method Detail

writeString

public static void writeString(DataOutput out,
                               String str)
                        throws IOException

Deprecated. Use IOUtil.writeCharArray(DataOutput, String) method instead.

Writes specified string to the specified data output in a compact form as a sequence of characters. Accepts null string as a valid value.

Throws:

IOException

readString

public static String readString(DataInput in)
                         throws IOException

Deprecated. Use IOUtil.readCharArrayString(java.io.DataInput) method instead.

Reads string from specified data input in a compact form as a sequence of characters. Returns null if such value was written to the stream.

Throws:

IOException
