Constructor Detail

AggregateReal

public AggregateReal(int init_size)

Create an aggregate of EXPRESS REAL with the given capacity.

Parameters:

init_size - initial size of the buffer to use

AggregateReal

public AggregateReal()

Create an aggregate of EXPRESS REAL numbers

Method Detail

getBuffer

protected Object getBuffer()

Description copied from class: AggregatePrimitive

Get the buffer object.

Specified by:

getBuffer in class AggregatePrimitive<Double>

createBuffer

protected Object createBuffer(int sz)

Description copied from class: AggregatePrimitive

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

Specified by:

createBuffer in class AggregatePrimitive<Double>

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 int getCapacity()

Description copied from class: AggregatePrimitive

Get the length of the buffer.

Specified by:

getCapacity in class AggregatePrimitive<Double>

getValue

public double getValue(int idx)

Parameters:

idx - the element to get.

Returns:

the value at the specified index.

get

public Double get(int idx)

Get the element at a particular element

Specified by:

get in interface List<Double>

The old value at the specified index.

set

public Double set(int index,
         Double value)

Set a value at a specified index

Specified by:

set in interface List<Double>

Overrides:

set in class AbstractList<Double>

Parameters:

index - of the element to set

value - the value to to be stored at the specified location.

Returns:

The old value at the specified index.

setObject

public void setObject(int index,
             Object element)

Set the value at a specified index

Parameters:
