BaseType - Boxed type of the array element; e.g., Double.

All Implemented Interfaces:

Iterable<BaseType>, Collection<BaseType>, List<BaseType>, PrimitiveArray<ArrayType,BaseType>, Sizable

public abstract class AbstractPrimitiveArray<ArrayType,BaseType>
extends AbstractList<BaseType>
implements PrimitiveArray<ArrayType,BaseType>

Abstract base class for primitive-type extensible arrays.

This class makes it easy to implement extensible arrays backed by fixed-size primitive type arrays, re-allocating and copying data as needed. To avoid frequent re-allocation, by default, the fixed-size array will be expanded by 50% when running out of space.

Constructor Detail

AbstractPrimitiveArray

public AbstractPrimitiveArray(Class<BaseType> type)

Constructs an extensible array of primitive type elements, backed by a fixed-size array.

Parameters:

type - the class of the primitive type

AbstractPrimitiveArray

public AbstractPrimitiveArray(Class<BaseType> type,
                              int size)

Constructs an extensible array of primitive type elements, backed by a fixed-size array.

Parameters:

type - the class of the primitive type

size - the initial size

AbstractPrimitiveArray

public AbstractPrimitiveArray(Class<BaseType> type,
                              ArrayType array)

Constructs an extensible array of primitive type elements, backed by the given fixed-size array.

Parameters:

array - the array to wrap

type - the class of the primitive type

Method Detail

getMaximumGrowth

public int getMaximumGrowth()

Description copied from interface: PrimitiveArray

Gets the maximal step size by which to grow the fixed-size array when running out of space.

Specified by:

getMaximumGrowth in interface PrimitiveArray<ArrayType,BaseType>

setMaximumGrowth

public void setMaximumGrowth(int growth)

Description copied from interface: PrimitiveArray

Sets the maximal step size by which to grow the fixed-size array when running out of space.

Specified by:

setMaximumGrowth in interface PrimitiveArray<ArrayType,BaseType>

copyArray

public ArrayType copyArray()

Description copied from interface: PrimitiveArray

Returns a copy of the primitive-array array.

The returned array is guaranteed to have List.size() elements.

Specified by:

copyArray in interface PrimitiveArray<ArrayType,BaseType>

Returns:

the fixed-size array

capacity

public int capacity()

Gets the current capacity of the backing array.

Specified by:

capacity in interface PrimitiveArray<ArrayType,BaseType>

ensureCapacity

public void ensureCapacity(int minCapacity)

Description copied from interface: PrimitiveArray

Makes sure the backing array at least a specified capacity.

After calling this method, the internal array will have at least minCapacity elements.

Specified by:

ensureCapacity in interface PrimitiveArray<ArrayType,BaseType>

Parameters:

minCapacity - the minimum capacity

insert

public void insert(int index,
                   int count)

Shifts the array to insert space at a specified index.

Specified by:

insert in interface PrimitiveArray<ArrayType,BaseType>

Parameters:

index - the index where the space should be inserted

count - the number of values to insert

delete

public void delete(int index,
                   int count)

Shifts the array to delete space starting at a specified index.

Specified by:

delete in interface PrimitiveArray<ArrayType,BaseType>

Parameters:

index - the index where the space should be deleted

count - the number of values to delete

set

public abstract BaseType set(int index,
                             BaseType element)

Specified by:

set in interface List<BaseType>

Overrides:

size

public int size()

Specified by:

size in interface Collection<BaseType>

Specified by:

size in interface List<BaseType>

Specified by:

size in interface Sizable
