Constructor Detail

DataFormat

public DataFormat(java.lang.String... ids)

Create a new DataFormat, specifying the set of ids that are associated with this data format. Typically the ids are one or more mime types. For each id, any data associated with this DataFormat will be registered on the clipboard. For example, suppose I had the following:

     DataFormat fmt = new DataFormat("text/foo", "text/bar");
     Clipboard clipboard = Clipboard.getSystemClipboard();
     ClipboardContent content = new ClipboardContent();
     content.pu(fmt, "Hello");
     clipboard.setContent(content);
 

With the above code, if I were to look on the clipboard, I'd find the String "Hello" listed both for "text/foo" and "text/bar" on the clipboard.

Parameters:

ids - The set of ids used to represent this DataFormat on the clipboard.

Throws:

java.lang.IllegalArgumentException - if one of the given mime types is already assigned to another DataFormat.

Method Detail

getIdentifiers

public final java.util.Set<java.lang.String> getIdentifiers()

Gets the unmodifiable set of identifiers for this DataFormat.

Returns:

an unmodifiable set that is never null.

toString

public java.lang.String toString()

Returns a string representation of this DataFormat object.

Overrides:

hashCode

public int hashCode()

Returns a hash code for this DataFormat object.

Overrides:

hashCode in class java.lang.Object

Returns:

a hash code for this DataFormat object.

equals

public boolean equals(java.lang.Object obj)

Indicates whether some other object is "equal to" this one.

Overrides:

equals in class java.lang.Object

Parameters:

obj - the reference object with which to compare.

Returns:

true if this object is equal to the obj argument; false otherwise.

lookupMimeType

public static DataFormat lookupMimeType(java.lang.String mimeType)

Looks for the DataFormat which has been previously created with the given mime type as one of its ids.

Parameters:

mimeType - If null or the empty string, then null is returned.

Returns:

The matching DataFormat
