public interface Block
extends org.jfree.ui.Drawable
```
A block is an arbitrary item that can be drawn (in Java2D space) within a rectangular area, has a preferred size, and can be arranged by an Arrangement manager.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`org.jfree.ui.Size2D`	`arrange(Graphics2D g2)` Arranges the contents of the block, with no constraints, and returns the block size.
`org.jfree.ui.Size2D`	`arrange(Graphics2D g2, RectangleConstraint constraint)` Arranges the contents of the block, within the given constraints, and returns the block size.
`Object`	`draw(Graphics2D g2, Rectangle2D area, Object params)` Draws the block within the specified area.
`Rectangle2D`	`getBounds()` Returns the current bounds of the block.
`String`	`getID()` Returns an ID for the block.
`void`	`setBounds(Rectangle2D bounds)` Sets the bounds of the block.
`void`	`setID(String id)` Sets the ID for the block.

```
String getID()
```
    Returns an ID for the block.
    
    Returns:
    
    An ID.
  - setID
```
void setID(String id)
```
    Sets the ID for the block.

    id - the ID.
  - arrange
```
org.jfree.ui.Size2D arrange(Graphics2D g2)
```
    Arranges the contents of the block, with no constraints, and returns the block size.
    
    Parameters:
    
    g2 - the graphics device.
    
    Returns:
    
    The size of the block.
  - arrange
```
org.jfree.ui.Size2D arrange(Graphics2D g2,
                            RectangleConstraint constraint)
```
    Arranges the contents of the block, within the given constraints, and returns the block size.
    
    Parameters:
    
    g2 - the graphics device.
    
    constraint - the constraint (null not permitted).
    
    Returns:
    
    The block size (in Java2D units, never null).
  - getBounds
```
Rectangle2D getBounds()
```
    Returns the current bounds of the block.
    
    Returns:
    
    The bounds.
  - setBounds
```
void setBounds(Rectangle2D bounds)
```
    Sets the bounds of the block.
    
    Parameters:
    
    bounds - the bounds.
  - draw
```
Object draw(Graphics2D g2,
            Rectangle2D area,
            Object params)
```
    Draws the block within the specified area. Refer to the documentation for the implementing class for information about the params and return value supported.
    
    Parameters:
    
    g2 - the graphics device.
    
    area - the area.
    
    params - optional parameters (null permitted).
    
    Returns:
    
    An optional return value (possibly null).
