public static final DataFlavor imageFlavor
Suppressed: The DataFlavor representing a Java Image class, where: 
     representationClass = java.awt.Image
     mimeType            = "image/x-java-image"

plainTextFlavor

public static final DataFlavor plainTextFlavor
Deprecated. as of 1.3. Use DataFlavor.getReaderForText( Transferable) instead of Transferable. getTransferData(DataFlavor.plainTextFlavor).

selectBestTextFlavor(java.awt.datatransfer.DataFlavor[])

paramString

private String paramString()

getTextPlainUnicodeFlavor

public static final DataFlavor getTextPlainUnicodeFlavor()
Enabled: Returns a DataFlavor representing plain text with Unicode encoding, where: 
     representationClass = java.io.InputStream
     mimeType            = "text/plain;
                            charset=<platform default Unicode encoding>"
Sun's implementation for Microsoft Windows use the encoding utf-16le. Sun's implementation for Solaris and Linux use the encoding iso-10646-ucs-2.

Returns:
a DataFlavor representing plain text with Unicode encoding

selectBestTextFlavor

public static final DataFlavor selectBestTextFlavor(DataFlavor[] availableFlavors)
Enabled: Selects the best text DataFlavor from an array of DataFlavors. Only DataFlavor.stringFlavor, and equivalent flavors, and flavors that have a primary MIME type of "text", are considered for selection.

Flavors are first sorted by their MIME types in the following order:

For example, "text/sgml" will be selected over "text/html", and DataFlavor.stringFlavor will be chosen over DataFlavor.plainTextFlavor.

If two or more flavors share the best MIME type in the array, then that MIME type will be checked to see if it supports the charset parameter.

The following MIME types support, or are treated as though they support, the charset parameter:

The following MIME types do not support, or are treated as though they do not support, the charset parameter: For "text/<other>" MIME types, the first time the JRE needs to determine whether the MIME type supports the charset parameter, it will check whether the parameter is explicitly listed in an arbitrarily chosen DataFlavor which uses that MIME type. If so, the JRE will assume from that point on that the MIME type supports the charset parameter and will not check again. If the parameter is not explicitly listed, the JRE will assume from that point on that the MIME type does not support the charset parameter and will not check again. Because this check is performed on an arbitrarily chosen DataFlavor, developers must ensure that all DataFlavors with a "text/<other>" MIME type specify the charset parameter if it is supported by that MIME type. Developers should never rely on the JRE to substitute the platform's default charset for a "text/<other>" DataFlavor. Failure to adhere to this restriction will lead to undefined behavior.

If the best MIME type in the array does not support the charset parameter, the flavors which share that MIME type will then be sorted by their representation classes in the following order: java.io.InputStream, java.nio.ByteBuffer, [B, <all others>.

If two or more flavors share the best representation class, or if no flavor has one of the three specified representations, then one of those flavors will be chosen non-deterministically.

If the best MIME type in the array does support the charset parameter, the flavors which share that MIME type will then be sorted by their representation classes in the following order: java.io.Reader, java.lang.String, java.nio.CharBuffer, [C, <all others>.

If two or more flavors share the best representation class, and that representation is one of the four explicitly listed, then one of those flavors will be chosen non-deterministically. If, however, no flavor has one of the four specified representations, the flavors will then be sorted by their charsets. Unicode charsets, such as "UTF-16", "UTF-8", "UTF-16BE", "UTF-16LE", and their aliases, are considered best. After them, the platform default charset and its aliases are selected. "US-ASCII" and its aliases are worst. All other charsets are chosen in alphabetical order, but only charsets supported by this implementation of the Java platform will be considered.

If two or more flavors share the best charset, the flavors will then again be sorted by their representation classes in the following order: java.io.InputStream, java.nio.ByteBuffer, [B, <all others>.

If two or more flavors share the best representation class, or if no flavor has one of the three specified representations, then one of those flavors will be chosen non-deterministically.

Parameters:
availableFlavors - an array of available DataFlavors
Returns:
the best (highest fidelity) flavor according to the rules specified above, or null, if availableFlavors is null, has zero length, or contains no text flavors
Since:
1.3

getReaderForText

public Reader getReaderForText(Transferable transferable)
                        throws UnsupportedFlavorException,
                               IOException
Enabled: Gets a Reader for a text flavor, decoded, if necessary, for the expected charset (encoding). The supported representation classes are java.io.Reader, java.lang.String, java.nio.CharBuffer, [C, java.io.InputStream, java.nio.ByteBuffer, and [B.

Because text flavors which do not support the charset parameter are encoded in a non-standard format, this method should not be called for such flavors. However, in order to maintain backward-compatibility, if this method is called for such a flavor, this method will treat the flavor as though it supports the charset parameter and attempt to decode it accordingly. See selectBestTextFlavor for a list of text flavors which do not support the charset parameter.

Parameters:
transferable - the Transferable whose data will be requested in this flavor
Returns:
a Reader to read the Transferable's data

If this flavor supports the charset parameter, it must be equivalent to DataFlavor.stringFlavor, or its representation must be java.io.Reader, java.lang.String, java.nio.CharBuffer, [C, java.io.InputStream, java.nio.ByteBuffer, or [B. If the representation is java.io.InputStream, java.nio.ByteBuffer, or [B, then this flavor's charset parameter must be supported by this implementation of the Java platform. If a charset is not specified, then the platform default charset, which is always supported, is assumed.

If this flavor does not support the charset parameter, its representation must be java.io.InputStream, java.nio.ByteBuffer, or [B.

See selectBestTextFlavor for a list of text flavors which support the charset parameter.

Returns:
true if this DataFlavor is a valid text flavor as described above; false otherwise
Since:
1.4

writeExternal

public void writeExternal(ObjectOutput os)
                   throws IOException
Suppressed: Serializes this DataFlavor.

Specified by:
writeExternal in interface Externalizable
Parameters:
os - the stream to write the object to
IOException

readExternal

public void readExternal(ObjectInput is)
                  throws IOException,
                         ClassNotFoundException
Suppressed: Restores this DataFlavor from a Serialized state.

Specified by:
readExternal in interface Externalizable
Parameters:
is - the stream to read data from in order to restore the object
IOException
ClassNotFoundException

clone

public Object clone()
             throws CloneNotSupportedException
Suppressed: Returns a clone of this DataFlavor.

Overrides:
clone in class Object
Returns:
a clone of this DataFlavor
CloneNotSupportedException

normalizeMimeTypeParameter

protected String normalizeMimeTypeParameter(String parameterName,
                                            String parameterValue)
Deprecated.  

Called on DataFlavor for every MIME Type parameter to allow DataFlavor subclasses to handle special parameters like the text/plain charset parameters, whose values are case insensitive. (MIME type parameter values are supposed to be case sensitive.

This method is called for each parameter name/value pair and should return the normalized representation of the parameterValue. This method is never invoked by this implementation from 1.1 onwards.

normalizeMimeType

protected String normalizeMimeType(String mimeType)
Deprecated.  

Called for each MIME type string to give DataFlavor subtypes the opportunity to change how the normalization of MIME types is accomplished. One possible use would be to add default parameter/value pairs in cases where none are present in the MIME type string passed in. This method is never invoked by this implementation from 1.1 onwards.
