Method Detail

clearAndEnsureCapacity

public static java.nio.ByteBuffer clearAndEnsureCapacity(java.nio.ByteBuffer buffer,
                                                         int elements)

Ensure the buffer's capacity is large enough to hold a given number of elements. If the input buffer is not large enough, a new buffer is allocated and returned.

Parameters:

elements - The required number of elements to be appended to 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.

clearAndEnsureCapacity

public static java.nio.CharBuffer clearAndEnsureCapacity(java.nio.CharBuffer buffer,
                                                         int elements)

Ensure the buffer's capacity is large enough to hold a given number of elements. If the input buffer is not large enough, a new buffer is allocated and returned.

Parameters:

elements - The required number of elements to be appended to 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.

toString

public static java.lang.String toString(java.nio.CharBuffer buffer)

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.

bytesToChars

public static java.nio.CharBuffer bytesToChars(java.nio.charset.CharsetDecoder decoder,
                                               java.nio.ByteBuffer bytes,
                                               java.nio.CharBuffer chars)

Convert byte buffer's content into characters. The input buffer's bytes are not consumed (mark is set and reset).

charsToBytes

public static java.nio.ByteBuffer charsToBytes(java.nio.charset.CharsetEncoder encoder,
                                               java.nio.CharBuffer chars,
                                               java.nio.ByteBuffer bytes)
                                        throws UnmappableInputException

Convert chars into bytes.

Throws:

UnmappableInputException
