public abstract class AggregatePrimitive<T>
extends AbstractList<T>
implements Aggregate<T>

Aggregate is Java primitive types. This class provides the base infrastructure for aggregates of primitives, but the actual buffer creation is handled in a subtype.

Field Detail

size

protected int size

Constructor Detail

AggregatePrimitive

public AggregatePrimitive(int init_size)

Create an aggregate of EXPRESS REAL with the given capacity.

Parameters:

init_size - initial size of the buffer to use

AggregatePrimitive

public AggregatePrimitive()

Method Detail

getBuffer

protected abstract Object getBuffer()

Get the buffer object.

createBuffer

protected abstract Object createBuffer(int sz)

Create a Java array of the type of the aggregate with the spefified size. This method must be overridded by the subtype.

Parameters:

sz - The requested size of the buffer.

Returns:

A Java array of the aggregate type of the requested size (e.g. int[]).

getCapacity

protected abstract int getCapacity()

Get the length of the buffer.

trimToSize

public void trimToSize()

Update the size of the buffer to the minimum size required by the data. This will optimize the storage requirements.

Specified by:

trimToSize in interface Aggregate<T>

clone

public Object clone()
             throws CloneNotSupportedException

Description copied from interface: Instance

Generate a shallow copy of this object

Specified by:

clone in interface Instance

Overrides:

clone in class Object

Returns:

A copy of this object

Throws:

CloneNotSupportedException - If this object cannot be cloned. This is not thrown be any ST-Developer class, but was provided in the java.lang.Object prototype for clone().

size

public int size()

Get the size of the aggregate

Specified by:

size in interface Collection<T>

Specified by:

size in interface List<T>

Specified by:

size in class AbstractCollection<T>

checkIndex

protected void checkIndex(int idx)

updateCapacity

protected void updateCapacity(int req_sz)
