Method Detail

setBufferAndAppended

public void setBufferAndAppended(byte[] dest,
                                 int app)

Needed in Java for when we write to the buffer directly. In C++, the SortKeyByteSink is a subclass of ByteSink and lower-level code can write to that. TODO: Can we make Java SortKeyByteSink have-a ByteArrayWrapper and write through to it? Or maybe create interface ByteSink, have SortKeyByteSink implement it, and have BOCSU write to that??

Append

public void Append(byte[] bytes,
                   int n)

Parameters:

bytes - the array of byte

n - the length of bytes to be appended

Append

public void Append(int b)

NumberOfBytesAppended

public int NumberOfBytesAppended()

GetRemainingCapacity

public int GetRemainingCapacity()

Overflowed

public boolean Overflowed()

AppendBeyondCapacity

protected abstract void AppendBeyondCapacity(byte[] bytes,
                                             int start,
                                             int n,
                                             int length)

Parameters:

bytes - the array of byte

start - the start index within the array to be appended

n - the length of bytes to be appended

length - the length of buffer required to store the entire data (i.e. already appended bytes + bytes to be appended by this method)

Resize

protected abstract boolean Resize(int appendCapacity,
                                  int length)
