Class TransferData
TransferData
class is a platform specific data structure for
describing the type and the contents of data being converted by a transfer agent.
As an application writer, you do not need to know the specifics of TransferData. TransferData instances are passed to a subclass of Transfer and the Transfer object manages the platform specific issues. You can ask a Transfer subclass if it can handle this data by calling Transfer.isSupportedType(transferData).
You should only need to become familiar with the fields in this class if you are implementing a Transfer subclass and you are unable to subclass the ByteArrayTransfer class.

format
public int formatSpecifies the size in bits of a single unit in pValue. (Warning: This field is platform dependent)IMPORTANT: This field is not part of the SWT public API. It is marked public only so that it can be shared within the packages provided by SWT. It is not available on all platforms and should never be accessed from application code.
This is most commonly 8 bits. -
pValue
public long pValuePointer to the data being transferred. (Warning: This field is platform dependent)IMPORTANT: This field is not part of the SWT public API. It is marked public only so that it can be shared within the packages provided by SWT. It is not available on all platforms and should never be accessed from application code.

result
public int resultThe result field contains the result of converting a java data type into a platform specific value. (Warning: This field is platform dependent)IMPORTANT: This field is not part of the SWT public API. It is marked public only so that it can be shared within the packages provided by SWT.
