Method Detail

getBytes

public byte[] getBytes()

Description copied from interface: ByteArray

This method gets the underlying byte-array of this buffer. You are only permitted to read the content from minimumIndex (typically currentIndex to maximumIndex. Only the creator of this object may modify this array.

Returns:

the buffer

See Also:

ByteArray.getCurrentIndex(), ByteArray.getMaximumIndex()

getBytesAvailable

public int getBytesAvailable()

Description copied from interface: ByteArray

This method gets the number of bytes available in this array. In other words this method returns ByteArray.getMaximumIndex() - ByteArray.getCurrentIndex() + 1.

Specified by:

getBytesAvailable in interface ByteArray

Specified by:

getBytesAvailable in interface ByteProvider

Overrides:

getBytesAvailable in class AbstractByteArray

Returns:

the bytes left in this array.

getMinimumIndex

public int getMinimumIndex()

Description copied from interface: ByteArray

This method gets the minimum index where to start reading in the byte array. It will be in the range from 0 to maximumIndex + 1. This is typically the same as the current index. However a mutable variant of a ByteArray may allow to modify (increase) the current-index. The value returned by this method can NOT be modified.

Returns:

the minimum index.

getCurrentIndex

public int getCurrentIndex()

Description copied from interface: ByteArray

This method gets the offset in the byte array. It will be in the range from 0 to maximumIndex + 1.

Returns:

the offset in the byte array.

getMaximumIndex

public int getMaximumIndex()

Description copied from interface: ByteArray

This method gets the maximum index in the buffer. It will be in the range from -1 to ByteArray.getBytes().length - 1.
A negative value (-1) indicates that the buffer does NOT contain data (payload).

Returns:

the maximumIndex
