Constructor Detail

HexTableModel

public HexTableModel(HexEditorComponent editor)

Creates the model.

Parameters:

editor - The parent hex editor.

Method Detail

getByte

public byte getByte(int offset)

Gets the byte at the specified offset in the document.

Parameters:

offset - The offset.

Returns:

The byte.

getByteCount

public int getByteCount()

Returns the number of bytes in the document.

Returns:

The size of the document, in bytes.

getBytes

public byte[] getBytes()

getBytesPerRow

public int getBytesPerRow()

Returns the number of bytes to display in a row.

Returns:

The number of bytes to display in a row.

getColumnCount

public int getColumnCount()

Returns the number of columns to display in the hex editor.

Returns:

The number of columns to display.

getColumnName

public java.lang.String getColumnName(int col)

Specified by:

getColumnName in interface javax.swing.table.TableModel

Overrides:

getColumnName in class javax.swing.table.AbstractTableModel

getRowCount

public int getRowCount()

Gets the number of rows to display in the hex editor.

Returns:

The number of rows to display.

getValueAt

public java.lang.Object getValueAt(int row,
                                   int col)

Returns the value to display at the specified cell in the table, as a String.

Parameters:

row - The row of the cell.

col - The column of the cell.

Returns:

The value to display.

redo

public boolean redo()

Redoes the last undoable edit undone.

Returns:

Whether there is another operation that can be redone after this one.

See Also:

undo()

removeBytes

public void removeBytes(int offset,
                        int len)

Removes bytes from the document.

Parameters:

offset - The offset at which to remove.

len - The number of bytes to remove. If this value is <= 0, nothing happens.

See Also:

replaceBytes(int, int, byte[])

replaceBytes

public void replaceBytes(int offset,
                         int len,
                         byte[] bytes)

Replaces bytes in the document.

Parameters:

offset - The offset of the range of bytes to replace.

len - The number of bytes to replace.

bytes - The bytes to replace with. If this is null or an empty array, then this method call will be equivalent to removeBytes(offset, len).

See Also:

removeBytes(int, int)

setBytes

public void setBytes(java.lang.String fileName)
              throws java.io.IOException

Sets the bytes displayed to those in the given file.

Parameters:

fileName - The name of a file.

Throws:

java.io.IOException - If an IO error occurs reading the file.

See Also:

setBytes(InputStream)

setBytes

public void setBytes(java.io.InputStream in)
              throws java.io.IOException

                       int col)

Sets the value of a cell in the table.

Specified by:

setValueAt in interface javax.swing.table.TableModel

Overrides:

setValueAt in class javax.swing.table.AbstractTableModel
