Method Detail

serializeHexLong

public static void serializeHexLong(long i,
                    Text t,
                    char toAppend)

Appends hex representation of the given number to the given string. If append is set to true, a comma is also appended to the text.

Parameters:

i -

t -

appendComma -

deserializeHexLong

public static long deserializeHexLong(byte[] buf,
                      int offset,
                      int len)

Parses only long from the given byte array (string). The long starts at offset and is len characters long.

Parameters:

buf -

offset -

len -

Returns:

consumeHexLong

public static long consumeHexLong(Text text,
                  char separator)

Deserializes and consumes a long from the given text. Consuming means all characters read for deserialization are removed from the given text. If separator is non-zero, a long is read and consumed up to the first occurrence of this separator. The separator is also consumed.

Parameters:

text -

separator -

Returns:

consumeDouble

public static double consumeDouble(Text text,
                   char separator)

Deserializes and consumes a double from the given text. Consuming means all characters read for deserialization are removed from the given text. If separator is non-zero, a double is read and consumed up to the first occurrence of this separator. The separator is also consumed.

Parameters:

text -

separator -

Returns:

serializeDouble

public static void serializeDouble(double d,
                   Text t,
                   char toAppend)

Appends hex representation of the given number to the given string. If append is set to true, a comma is also appended to the text.

Parameters:

i -

t -

appendComma -
