Method Detail

getTypes

public java.lang.String[] getTypes()

Description copied from class: ContentViewer

Returns a list of content types that this component can handle. This will usually be a list of MIME Types, but may also include other notions of type known to be understood by the users of ContentHandlerFactory.

Specified by:

getTypes in class ContentViewer

init

public void init(java.lang.String type,
                 java.io.InputStream data,
                 boolean viewOnly)
          throws java.io.IOException

Description copied from class: ContentViewer

Initializes the handler. This should only be called once per instance, and is guaranteed to have been called when this component is provided by the ContentHandlerFactory. The viewOnly parameter signals to ContentEditor implementations that editing capabilities are not desired by the caller.

Specified by:

init in class ContentViewer

Throws:

java.io.IOException

setXML

public void setXML(boolean isXML)

setContent

public void setContent(java.io.InputStream data)
                throws java.io.IOException

Description copied from class: ContentViewer

Re-initializes the handler given new input data. The old data can be discarded.

Specified by:

setContent in class ContentViewer

Throws:

java.io.IOException

getComponent

public javax.swing.JComponent getComponent()

Description copied from class: ContentViewer

Get the JComponent.

Specified by:
