Method Details

writeBoolean

public void writeBoolean(boolean v)
                  throws IOException

Throws:

IOException

See Also:

• CompressedReader.readBoolean()

writeByte

public void writeByte(int v)
               throws IOException

Throws:

IOException

See Also:

• CompressedReader.readByte()

writeLong

public void writeLong(long v)
               throws IOException

Throws:

IOException

See Also:

• CompressedReader.readLong()

writeInt

public void writeInt(int v)
              throws IOException

Throws:

IOException

See Also:

• CompressedReader.readInt()

writeChars

public void writeChars(char[] name)
                throws IOException

Write the given name UTF8 encoded.

Parameters:

name - chars to write

Throws:

IOException

See Also:

• CompressedReader.readChars()

writeIntWithHint

public void writeIntWithHint(int v,
 int[] typical)
                      throws IOException

Writes v using a list of likely values "typical". If v is element of "typical" then encode v as an index. Otherwise encoded as typical.length and plain encoded v;

Parameters:

v - the number to write

typical - a list of most used values

Throws:

IOException

See Also:

• CompressedReader.readIntWithHint(int[])

writeIntInRange

public void writeIntInRange(int v,
 int range)
                     throws IOException

Write a number v which must be 0 <= v < range. Otherwise IllegalArgumentException is thrown. Encodes only as many bytes as needed. I.e. skipping the high bytes.

Parameters:

v - the number to write.

range - the maximal possible value of v + 1

Throws:

IOException

See Also:

• CompressedReader.readIntInRange(int)

writeStringUsingDictionary

public void writeStringUsingDictionary(String v)
                                throws IOException

Writes the given String. If the String was already written before its index in the dictionary is encoded as index+1. Otherwise a 0 index is encoded and then the String is encoded as UTF8 and stored into dictionary.

Parameters:

v - the String to write

Throws:

IOException

See Also:

• CompressedReader.readStringUsingDictionary()

writeStringUsingLast

public void writeStringUsingLast(String name)
                          throws IOException

Writes the given String. Encoded like a char array using last string.

Parameters:

name - the String to write.

Throws:

IOException

See Also:

• CompressedReader.readStringUsingLast()

writeCharsUsingLast

public void writeCharsUsingLast(char[] name)
                         throws IOException

Writes the given char array and remember it. Encoded by writing the length of common leading chars with the last given array followed by the remaining chars using a dictionary. Works best if the names are written in binary sorted order.

Parameters:

name - the char array to write

Throws:

IOException

• CompressedReader.readCharsUsingLast()
