Transfer

<code>Transfer</code> provides a mechanism for converting between a java representation of data and a platform specific representation of data and vice versa. It is used in data transfer operations such as drag and drop and clipboard copy/paste.

<p>You should only need to become familiar with this class if you are implementing a Transfer subclass and you are unable to subclass the ByteArrayTransfer class.</p>

Functions

getSupportedTypes TransferData[] getSupportedTypes(): Returns a list of the platform specific data types that can be converted using this transfer agent.
getTypeIds int[] getTypeIds(): Returns the platform specific ids of the data types that can be converted using this transfer agent.
getTypeNames String[] getTypeNames(): Returns the platform specific names of the data types that can be converted using this transfer agent.
isSupportedType bool isSupportedType(TransferData transferData): Returns true if the <code>TransferData</code> data type can be converted using this transfer agent, or false otherwise (including if transferData is <code>null</code>).
javaToNative void javaToNative(Object object, TransferData transferData): Converts a java representation of data to a platform specific representation of the data.
nativeToJava Object nativeToJava(TransferData transferData): Converts a platform specific representation of data to a java representation.
validate bool validate(Object object): Test that the object is of the correct format for this Transfer class.

Static functions

registerType int registerType(String formatName): Registers a name for a data type and returns the associated unique identifier.
