API review: Conversion methods in Binding API

[Michael Heinrichs]

Hi,

there are sometimes situations, when a developer has a general typed value, but needs a specific type, e.g. a user may have an ObjectProperty<Integer> but needs an ObservableIntegerValue. I want to add some conversion methods for these kind of cases. http://javafx-jira.kenai.com/browse/RT-19020

class BooleanExpression:
public static BooleanExpression booleanExpression(ObservableValue<Boolean>)
The current booleanExpression() method will be marked as deprecated and should be removed when we do an incompatible update of the JavaFX API. Same for the methods in DoubleExpression etc.

class DoubleExpression:
public static <T extends Number> DoubleExpression doubleExpression(ObservableValue<T>)

class FloatExpression:
public static <T extends Number> FloatExpression floatExpression(ObservableValue<T>)

class IntegerExpression:
public static <T extends Number> IntegerExpression integerExpression(ObservableValue<T>)

class LongExpression:
public static <T extends Number> LongExpression longExpression(ObservableValue<T>)

class ObjectExpression:
public BooleanBinding asBoolean()
public DoubleBinding asDouble()
public FloatBinding asFloat()
public IntegerBinding asInteger()
public LongBinding asLong()
The bindings returned by these methods will return the default value, if the type of the wrapped Object does not match the expected.

class Bindings:
public static BooleanExpression convertToBoolean(ObservableValue<Boolean>)
public static <T extends Number> DoubleExpression convertToDouble(ObservableValue<T>)
public static <T extends Number> FloatExpression convertToFloat(ObservableValue<T>)
public static <T extends Number> IntegerExpression convertToInteger(ObservableValue<T>)
public static <T extends Number> LongExpression convertToLong(ObservableValue<T>)

Thanks,
Michael
