AsciiSequenceView

public AsciiSequenceView(DirectBuffer buffer,
                         int offset,
                         int length)

Construct a view over a DirectBuffer from an offset for a given length..

Parameters:

buffer - containing the ASCII sequence.

offset - at which the ASCII sequence begins.

length - of the ASCII sequence in bytes.

Method Detail

length

public int length()

Specified by:

length in interface CharSequence

buffer

public DirectBuffer buffer()

Gets the underlying buffer which this is a view over.

Returns:

the underlying buffer which this is a view over.

offset

public int offset()

Gets the offset into the underlying buffer.

Returns:

the offset into the underlying buffer.

charAt

public char charAt(int index)

Specified by:

charAt in interface CharSequence

subSequence

public AsciiSequenceView subSequence(int start,
                                     int end)

Specified by:

subSequence in interface CharSequence

wrap

public AsciiSequenceView wrap(DirectBuffer buffer,
                              int offset,
                              int length)

Wrap a range of an existing buffer containing an ASCII sequence.

Parameters:

buffer - containing the ASCII sequence.

offset - at which the ASCII sequence begins.

length - of the ASCII sequence in bytes.

Returns:

this for a fluent API.

reset

public void reset()

Reset the view to null.

getBytes

public int getBytes(MutableDirectBuffer dstBuffer,
                    int dstOffset)

Copy the bytes from a view into a provided buffer.

Parameters:

dstBuffer - into which the bytes will be copied.

dstOffset - offset in the destination buffer to begin the copy.

Returns:

the number of bytes copied.

toString

public String toString()

Specified by:

toString in interface CharSequence

Overrides:

toString in class Object
