public LargeStringBuffer(int minAllocation, int maxAllocation)
minAllocation
- initial allocation size for each segment (including the first). If minAllocation
exceeds maxAllocation, it is rounded down to the value of maxAllocationmaxAllocation
- maximum allocation size for each segment. When a segment reaches this
size, a new segment is created rather than appending more characters to the existing segment.
However, a segment may have size greater than maxAllocation if the data is appended in a single chunk
of size maxAllocation.public void append(java.lang.CharSequence data)
