public abstract class AbstractDoubleProperty

extends AbstractNumericProperty

Abstract implementation of a Double property.

Data is stored in the associated PropertyData object as a Double object. This is immutable so can be directly returned.

Method Detail

toDouble

public java.lang.Double toDouble()

Description copied from interface: NumericProperty

Get the property's value as a Double.

Specified by:

toDouble in interface NumericProperty

Overrides:

toDouble in class AbstractNumericProperty

See Also:

NumericProperty#toDouble()

toBigDecimal

public java.math.BigDecimal toBigDecimal()

Description copied from interface: NumericProperty

Get the property's value as a BigDecimal.

Returns:

the property value as a BigDecimal

See Also:

NumericProperty#toBigDecimal()

compareTo

public int compareTo(java.lang.Object object)

See Also:

Comparable.compareTo(Object)

convertObjectToDouble

protected java.lang.Double convertObjectToDouble(java.lang.Object object)

Convert an Object to a typecast Double, throwing an exception if unable to convert.

Parameters:

object -

Returns:

Double derived from the object

set

public void set(java.lang.Object propertyValue)

Description copied from interface: Property

Set the property's value as an object. The object type should be appropriate for the type of property. If necessary, the object will be cloned before it is stored internally. Implementations will recognise as many types of object passed in as possible. Null should always be accepted, primitive types will be reset back to zero/false.

If a String is passed in, it can be parsed in various ways. If the results of toDataString() are passed in, it must reconstitute the original value.

Specified by:

set in interface Property

Specified by:

set in class AbstractProperty

Parameters:

propertyValue - an Object to set the property's value to

See Also:

Property#set(Object)

set

public void set(long propertyValue)

Description copied from interface: NumericProperty

Set the property's value.

Parameters:

propertyValue - a value to set the property's value to

See Also:
