Method Detail

ensureCapacity

public static java.nio.ByteBuffer ensureCapacity(java.nio.ByteBuffer buffer,
                                                 int capacity)

Ensure the byte buffer's capacity. If a new buffer is allocated, its content is empty (the old buffer's contents is not copied).

Parameters:

capacity - The required capacity of the buffer.

buffer - The buffer to check or null if a new buffer should be allocated.

Returns:

Returns the same buffer or a new buffer with the given capacity.

ensureCapacity

public static java.nio.CharBuffer ensureCapacity(java.nio.CharBuffer buffer,
                                                 int capacity)

Ensure the char buffer's capacity. If a new buffer is allocated, its content is empty (the old buffer's contents is not copied).

Parameters:

capacity - The required capacity of the buffer.

buffer - The buffer to check or null if a new buffer should be allocated.

Returns:

Returns the same buffer or a new buffer with the given capacity.

toString

public static java.lang.String toString(java.nio.ByteBuffer buffer,
                                        java.nio.charset.Charset charset)

Parameters:

buffer - The buffer to convert to a string.

charset - The charset to use when converting bytes to characters.

Returns:

A string representation of buffer's content.

toArray

public static byte[] toArray(java.nio.ByteBuffer buffer)

Parameters:

buffer - The buffer to read from.

Returns:

Returns the remaining bytes from the buffer copied to an array.

sharedPrefixLength

static int sharedPrefixLength(java.nio.ByteBuffer a,
                              int aStart,
                              java.nio.ByteBuffer b,
                              int bStart)

Compute the length of the shared prefix between two byte sequences.

sharedPrefixLength

static int sharedPrefixLength(java.nio.ByteBuffer a,
                              java.nio.ByteBuffer b)

Compute the length of the shared prefix between two byte sequences.
