Class DataFlavor<T>

java.lang.Object
oracle.adf.view.rich.datatransfer.DataFlavor<T>

All Implemented Interfaces:

java.io.Serializable

public final class DataFlavor<T>

extends java.lang.Object

implements java.io.Serializable

Object identifying a kind of Data that can be retrieved from a Transferable. The type allows more flexibility than simply using a Java Class, and supports represetnation in other type systems. The DataFlavor instances are parameterized by the Java Class returned when the data for the DataFlavor is requested from the Transferable.

Method Detail

getDataFlavor

public static <S> DataFlavor<S> getDataFlavor(java.lang.Class<S> representationClass)

Returns a DataFlavor representing data of the specified Java Class and no discriminant.

Parameters:

representationClass - Java Class of data that this DataFlavor will retrieve

Returns:

The DataFlavor for the representation class

getDataFlavor

public static <S> DataFlavor<S> getDataFlavor(java.lang.Class<S> representationClass,
                                              java.lang.String discriminant)

Returns a DataFlavor representing data of the specified Java Class and optional discriminant. The discriminant is used to handles cases where the Java Class alone is insufficient to discriminate between allowed and unallowed data.

Parameters:

representationClass -

discriminant -

Returns:

a DataFlavor representing data of the specified Java Class

getDataFlavor

public static <S> DataFlavor<S> getDataFlavor(DataFlavor<S> baseFlavor,
                                              java.lang.String discriminant)

Returns a DataFlavor based on another flavor with a discriminant. The returned DataFlavor will use the representation class of the baseFlavor with the passed in discriminant.

Parameters:

baseFlavor -

discriminant -

Returns:

a DataFlavor

getErasedDataFlavor

public static DataFlavor<?> getErasedDataFlavor(java.lang.Class<?> representationClass,
                                                java.lang.String discriminant)

isCompatibleWith

public boolean isCompatibleWith(java.lang.Object o)

Returns true if the DataFlavor is compatible with the specified instance.

Parameters:

o -

Returns:

true if compatible

getFlavorClass

public java.lang.Class<T> getFlavorClass()

Returns the Java Class this DataFlavor represents.

Returns:

The Java Class represented by this Flavor.

See Also:

getDiscriminant()

getDiscriminant

public java.lang.String getDiscriminant()

Returns the optional discriminant used when comparing DataFlavors with the same FlavorClass.

Returns:

the discriminant, if any
