Method Detail

readBitSet

public static java.util.BitSet readBitSet(java.io.DataInputStream in,
                                          int byteCount)
                                   throws java.io.IOException

Read bit set of byteCount bytes from a DataInputStream (in).

Stream representation:

byte[byteCount] bytes

Where bit i is represented as
bytes[i>>3] & (1 << (i & 7)).

Parameters:

in - stream to read from

byteCount - number of bytes to read

Returns:

a BitSet

Throws:

java.io.IOException

toEnumSet

public static <E extends java.lang.Enum<E>> java.util.EnumSet<E> toEnumSet(java.lang.Class<E> enumType,
                                                                           java.util.BitSet bits)

Convert a BitSet into an EnumSet. Note that conversion of EnumSets into BitSets and vice versa is generally not a good serialization mechanism for EnumSets as it relies on the enum ordinals and bypasses the binary compatibility serialization of Enum and EnumSet. However, for efficient communication with non-Java code, it can be useful. It is recommended that the ordinals of Enums used with this method are explicitly specified and verified at construction time.

Type Parameters:

E -

Parameters:

enumType -

bits -

Returns:

an EnumSet

readEnumSet

public static <E extends java.lang.Enum<E>> java.util.EnumSet<E> readEnumSet(java.lang.Class<E> enumType,
                                                                             java.io.DataInputStream in,
                                                                             int byteCount)
                                                                  throws java.io.IOException
