Method Details

readFNum

public void readFNum()

read the next funky floating point number from the input stream. value gets put into the fnum field.

getIndexSize

public int getIndexSize(int loc)

get the size of the dictionary located within the stream at some offset.

Parameters:

loc - the index of the start of the dictionary
