Method Detail
-
getBasis
public Size getBasis()
Returns the base size, which is not-null
.- Returns:
- the base size
- Since:
- 1.1
-
getLowerBound
public Size getLowerBound()
Returns the optional lower bound.- Returns:
- the optional lower bound
- Since:
- 1.1
-
getUpperBound
public Size getUpperBound()
Returns the optional upper bound.- Returns:
- the optional upper bound
- Since:
- 1.1
-
maximumSize
public int maximumSize(java.awt.Container container, java.util.List components, FormLayout.Measure minMeasure, FormLayout.Measure prefMeasure, FormLayout.Measure defaultMeasure)
Returns this size as pixel size. Neither requires the component list nor the specified measures. Honors the lower and upper bound.Invoked by
FormSpec
to determine the size of a column or row.- Specified by:
maximumSize
in interfaceSize
- Parameters:
container
- the layout containercomponents
- the list of components to measureminMeasure
- the measure used to determine the minimum sizeprefMeasure
- the measure used to determine the preferred sizedefaultMeasure
- the measure used to determine the default size- Returns:
- the maximum size in pixels
- See Also:
FormSpec.maximumSize(Container, List, FormLayout.Measure, FormLayout.Measure, FormLayout.Measure)
-
compressible
public boolean compressible()
Describes if this Size can be compressed, if container space gets scarce. Used by the FormLayout size computations in#compressedSizes
to check whether a column or row can be compressed or not.BoundedSizes are compressible if the base Size is compressible.
- Specified by:
compressible
in interfaceSize
- Returns:
true
if and only if the basis is compressible- Since:
- 1.1
-
equals
public boolean equals(java.lang.Object object)
Indicates whether some other BoundedSize is "equal to" this one.- Overrides:
equals
in classjava.lang.Object
- Parameters:
object
- the object with which to compare- Returns:
true
if this object is the same as the object argument,false
otherwise.- See Also:
Object.hashCode()
,Hashtable
-
hashCode
public int hashCode()
Returns a hash code value for the object. This method is supported for the benefit of hashtables such as those provided byjava.util.Hashtable
.- Overrides:
hashCode
in classjava.lang.Object
- Returns:
- a hash code value for this object.
- See Also:
Object.equals(Object)
,Hashtable
-
toString
public java.lang.String toString()
Returns a string representation of this size object.Note: This string representation may change at any time. It is intended for debugging purposes. For parsing, use
encode()
instead.- Overrides:
toString
in classjava.lang.Object
- Returns:
- a string representation of this bounded size
