public Class CMapStrings

extends Object
Class Inheritance
Imports
java.nio.charset.StandardCharsets, java.util.ArrayList, .List
Many CMaps are using the same values for the mapped strings. This class provides all common one- and two-byte mappings to avoid duplicate strings.

public static byte[] getByteValue(byte[] bytes)

Get a singleton instance of the given combination of bytes to avoid multiple instances for same value. The values are limited to one and two-byte sequences. Any longer byte sequence produces null as return value.

Parameters
bytes:byte[]

the given combination of bytes

Returns:byte[]

a singleton instance for the given combination of bytes

getIndexValueback to summary
public static Integer getIndexValue(byte[] bytes)

Get an Integer instance of the given combination of bytes. Each value is a singleton to avoid multiple instances for same value. The values are limited to one and two-byte sequences. Any longer byte sequence produces null as return value.

Parameters
bytes:byte[]

the given combination of bytes

Returns:Integer

the Integer representation for the given combination of bytes

getMappingback to summary
public static String getMapping(byte[] bytes)

Get the mapped string value for the given combination of bytes. The mapping is limited to one and two-byte mappings. Any longer byte sequence produces null as return value.

Parameters
bytes:byte[]

the given combination of bytes

Returns:String

the string representation for the given combination of bytes
