getProperty

public Property getProperty(java.lang.String pathName)

Description copied from interface: HasProperties

Returns a property associated with a specified path name. All properties exported by this object must have a name which is a valid Java identifier. Specifying one of these names causes the corresponding Property to be returned. Handles to subproperties can also be obtained by delimiting the sub-property name(s) by '.' characters. A sub-property exists if the value of a property is itself an object which exports properties. It is only possible to obtain a sub-property handle if each of its ancestor properties exports their values by reference.

Specified by:

getProperty in interface HasProperties

Parameters:

pathName - name of the desired property or sub-property

Returns:

handle to the property

getAllPropertyInfo

public PropertyList getAllPropertyInfo()

Description copied from interface: HasProperties

Returns a list giving static information about all properties exported by this object.

Specified by:

getAllPropertyInfo in interface HasProperties

Returns:

static information for all exported properties

getPropertyInfo

public PropertyInfo getPropertyInfo()

Description copied from interface: CompositeProperty

If this object is a property, returns the corresponding information

Specified by:

getPropertyInfo in interface CompositeProperty

Returns:

property information for this object

setPropertyInfo

public void setPropertyInfo(PropertyInfo info)

Description copied from interface: CompositeProperty

Sets the property information for this property.

Specified by:

setPropertyInfo in interface CompositeProperty

Parameters:

info - property information

getPropertyHost

public HasProperties getPropertyHost()

Description copied from interface: CompositeProperty

Returns the host for this property

Specified by:

getPropertyHost in interface CompositeProperty

Returns:

host for this property

setPropertyHost

public void setPropertyHost(HasProperties newParent)

Description copied from interface: CompositeProperty

Sets the host for this property.

Specified by:

setPropertyHost in interface CompositeProperty

Parameters:

newParent - host for this property

getColor3Value

public static int getColor3Value(java.awt.Color c)

getColor4Value

public static int getColor4Value(java.awt.Color c)

getRGB

public void getRGB(double a,
                   byte[] rgb)

Description copied from interface: ColorMap

Fills an array with the interpolated color values in RGB format

Specified by:

getRGB in interface ColorMap

Parameters:

a - input, usually in the range [0,1]

rgb - output color

getHSV

public void getHSV(double a,
                   byte[] hsv)

Description copied from interface: ColorMap

Fills an array with the interpolated color values in HSV format

Specified by:

getHSV in interface ColorMap

Parameters:

a - input, usually in the range [0,1]

hsv - output color

copy

public abstract ColorMapBase copy()

clone

public ColorMapBase clone()
                   throws java.lang.CloneNotSupportedException

Description copied from interface: CompositeProperty

Returns a clone of this composite property.

Specified by:

clone in interface CompositeProperty

Specified by:

clone in interface Clonable

Overrides:

clone in class java.lang.Object

Returns:

clone of this property

Throws:

java.lang.CloneNotSupportedException

write

public void write(java.io.PrintWriter pw,
                  NumberFormat fmt,
                  java.lang.Object ref)
           throws java.io.IOException

Writes a text description of this element to a PrintWriter. The text description should be compatable with scan and complete enough to allow full reconstruction of the element.

Specified by:

write in interface Scannable

Parameters:

pw - stream for writing the element

fmt - numeric formating information

ref - optional reference object which can be used for producing references to other objects

Throws:

java.io.IOException - if an I/O error occured

isWritable

public boolean isWritable()

Returns true if this component should in fact be written to secondary storage. This gives subclasses control over whether or not they are actually written out.

Specified by:

isWritable in interface Scannable

Returns:

true if this component should be written to secondary storage.

scan

public void scan(ReaderTokenizer rtok,
                 java.lang.Object ref)
          throws java.io.IOException

Scans this element from a ReaderTokenizer. The expected text format is assumed to be compatible with that produced by write.

Specified by:

scan in interface Scannable

Parameters:

rtok - Tokenizer from which to scan the element

ref - optional reference object which can be used for resolving references to other objects

Throws:

java.io.IOException - if an I/O or formatting error occured
