Method Detail

getMinSize

public StrictDimension getMinSize(java.lang.Object e)

Parameters:

e - the layout cache key.

Returns:

The minimum size.

getPrefSize

public StrictDimension getPrefSize(java.lang.Object e)

Returns the preferred size of ???.

Parameters:

e - the layout cache key.

Returns:

The preferred size.

setMinSize

public void setMinSize(Element element,
                       StrictDimension d)

Sets the minimum size of the element as computed by the layout manager.

Parameters:

element - the element.

d - the minimum size.

setPrefSize

public void setPrefSize(Element element,
                        StrictDimension d)

Sets the preferred size of the element as computed by the layout manager.

Parameters:

element - the element.

d - the minimum size.

isCachable

public boolean isCachable(Element e)

Returns true if the specified element is cachable, and false otherwise. If the element itself is dynamic, the element is considered cachable. If the element is a band and contains a dynamic element as its child, it is considered uncachable.

Parameters:

e - the element.

Returns:

A boolean.
