Method Summary

java.io.File	autocorrectFile(java.io.File file) Attempts to find a file based on the provided file if the implementation does not accept the file as it's passed in.
javax.swing.filechooser.FileFilter	getFileFilter()
boolean	isLoadCapable()
boolean	load(javax.swing.JTable table, java.io.File file) Loads a document into the model behind the table.
boolean	save(javax.swing.JTable table, java.io.File file) Persists the document from the model behind the table.

Method Detail

isLoadCapable

boolean isLoadCapable()

Returns:

true if the implementation can load a document as well as persist it

getFileFilter

javax.swing.filechooser.FileFilter getFileFilter()

Returns:

an object that knows how to accept and reject files in accordance with the implementation

load

boolean load(javax.swing.JTable table,
             java.io.File file)
             throws java.io.IOException,
                    java.lang.UnsupportedOperationException

Loads a document into the model behind the table.

Returns:

true if the document was loaded successfully

Throws:

java.lang.UnsupportedOperationException - if the implementation is not capable of loading documents as per isLoadCapable() method

java.io.IOException - if an IO problem occurred during loading the document

isLoadCapable()

save

boolean save(javax.swing.JTable table,
             java.io.File file)
             throws java.io.IOException

Persists the document from the model behind the table.

Returns:

true if the document was persisted successfully

Throws:

java.io.IOException - if an IO problem occurred during persisting the document

autocorrectFile

java.io.File autocorrectFile(java.io.File file)

Attempts to find a file based on the provided file if the implementation does not accept the file as it's passed in. A typical implementation of this would autocomplete a file extension. Acceptance of a file is tested by getFileFilter().accept(file).
