code: public void setPomModel( PomModel pomModel ) {
          this.pomModel = pomModel;
          if ( srcMfs.isAvailable( "pom.xml" ) ) {
              this.pomXml = srcMfs.getBytes( "pom.xml" );
          }
      }
docs: This can be used for performance reason to avoid the recomputation of the pomModel when it is already available
