Interface Gene

All Superinterfaces

Serializable

public interface Gene
extends Serializable

Gene represents a named parameter intended to affect some aspect of Look and Feel rendering. Genes are used in Look and Feel resources via runtime evaluation of tokens specified in skin or skeleton render dependencies. For example:

 <style type="text/css">
  .bea-portal-body { background-color: ${BodyBackgroundColor}; }
 </style>
 

Where ${BodyBackgroundColor} is a token which will be replaced with the value of the "BodyBackgroundColor" gene at runtime. Gene values may also contain tokens, and all such tokens will be fully expanded when the gene value is evaluated.

Implementations of this interface by other parties must not be expected to compile without change in future versions of Oracle Weblogic Portal.

Method Summary

String	evaluateValue(javax.servlet.http.HttpServletRequest request) Returns the evaluated gene value.
Chromosome	getChromosome() Returns the related chromosome.
String	getName() Returns the gene name.
String	getValue() Returns the raw gene value.

Method Detail

getName

String getName()

Returns the gene name.

getValue

String getValue()

Returns the raw gene value. This value will be the exact value specified in the gene configuration; that is, any tokens in the gene value will not be evaluated.

Returns

The raw gene value

See Also

evaluateValue(HttpServletRequest)

getChromosome

Chromosome getChromosome()

Returns the related chromosome.

evaluateValue

String evaluateValue(javax.servlet.http.HttpServletRequest request)
                     throws MutationException

Returns the evaluated gene value. Any tokens in the raw gene value will be fully expanded; that is, token substitution will continue until all tokens have been resolved.

Parameters

request - The current request

Returns

The evaluated gene value

Throws

MutationException - The first exception thrown by a mutator in the mutator chain associated with this gene, if any
