  DocumentFilter

Constructor Summary
`DocumentFilter.FilterBypass()`

Method Summary
`abstract Document` | `getDocument()` Returns the Document the mutation is occuring on.
`abstract void` | `insertString(int offset, String string, AttributeSet attr)` Inserts the specified text, bypassing the DocumentFilter.
`abstract void` | `remove(int offset, int length)` Removes the specified region of text, bypassing the DocumentFilter.
`abstract void` | `replace(int offset, int length, String string, AttributeSet attrs)` Deletes the region of text from `offset` to `offset + length`, and replaces it with `text`.
