Method Details
-
grow
int grow(int currentBufferLength, int elementsCount, int expectedAdditions) throws BufferAllocationException - Parameters:
currentBufferLength
- Current size of the array (buffer). This number should comply with the strategy's policies (it is a result of initial rounding or further growCalls). It can also be zero, indicating the growth from an empty buffer.elementsCount
- Number of elements stored in the buffer.expectedAdditions
- Expected number of additions (resize hint).- Returns:
- Must return a new size at least as big as to hold
elementsCount + expectedAdditions
. - Throws:
BufferAllocationException
- If the sizing strategy cannot grow the buffer (for example due to constraints or memory limits).
