MaxSizedIntArrayList

public MaxSizedIntArrayList(int maxSize,
 int expectedElements)

New instance with sane defaults.

Parameters:

maxSize - The maximum size this list can grow to

expectedElements - The expected number of elements guaranteed not to cause buffer expansion (inclusive).

MaxSizedIntArrayList

public MaxSizedIntArrayList(MaxSizedIntArrayList list)

Creates a new list from the elements of another list in its iteration order.

Method Details

ensureBufferSpace

protected void ensureBufferSpace(int expectedAdditions)

Description copied from class: IntArrayList

Ensures the internal buffer has enough free slots to store expectedAdditions. Increases internal buffer size if needed.

Overrides:

hashCode

public int hashCode()

Overrides:

hashCode in class IntArrayList

equals

public boolean equals(Object obj)

Returns true only if the other object is an instance of the same class and with the same elements and maxSize.

Overrides:

equals in class IntArrayList

ramBytesUsed

public long ramBytesUsed()

Description copied from interface: Accountable

Return the memory usage of this object in bytes. Negative values are illegal.

Specified by:

ramBytesUsed in interface Accountable

Overrides:
