com.carrotsearch.hppc.BoundedProportionalArraySizingStrategy
Resizing (growth) strategy for array-backed buffers.

Method Summary

Modifier and TypeMethod and Description
public int

Returns:

Must return a new size at least as big as to hold elementsCount + expectedAdditions.
grow(int
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.
currentBufferLength, int
Number of elements stored in the buffer.
elementsCount, int
Expected number of additions (resize hint).

public int grow(int currentBufferLength, int elementsCount, int expectedAdditions) throws BufferAllocationException
Parameters
currentBufferLength:int

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:int

Number of elements stored in the buffer.

expectedAdditions:int

Expected number of additions (resize hint).

Returns:int

Must return a new size at least as big as to hold elementsCount + expectedAdditions.

Exceptions
BufferAllocationException:
If the sizing strategy cannot grow the buffer (for example due to constraints or memory limits).
