capacity - is the length of the internal buffer.public ByteArrayImpl(byte[] buffer)
buffer - is the internal buffer.public ByteArrayImpl(byte[] buffer,
int startIndex,
int maximumIndex)
buffer - is the internal buffer.startIndex - is the current index as well as the minimum
index.maximumIndex - is the maximum index.public byte[] getBytes()

ByteArraybyte array.public int getMinimumIndex()
ByteArraybyte array. It will be in the
range from 0 to maximumIndex + 1current 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.public int getMaximumIndex()
ByteArraybuffer. It will be in the range from -1 to
ByteArray.getBytes().length - 1-1) indicates that the buffer does NOT contain data (payload).protected void setMaximumIndex(int maximumIndex)
maximumIndex. This may be useful if the buffer should be reused.
maximumIndex - is the maximumIndex to set. It has to be in the range from 0
( currentIndex - 1getBytes().lengthpublic ByteArrayImpl createSubArray(int minimum, int maximum)
ByteArrayByteArray with the same bytes but the given indices. minimum and maximum index are both equal to the
current indices of this ByteArray this method may return the instance itself ( this) rather than
creating a new one.createSubArray in interface ByteArraycreateSubArray in class AbstractByteArrayminimum - is the minimumIndex and the currentIndex for
the new ByteArray. It has to be greater or equal to the minimumIndex of
this ByteArray.maximum - is the maximumIndex for the new ByteArray.ByteArray with the given indices.Copyright © 2001–2016 mmm-Team. All rights reserved.
