ohrstrom@1504 | 48 | * pubapis of the packages. |
ohrstrom@1504 | 49 | * |
ohrstrom@1504 | 50 | * The transform implementation must: |
ohrstrom@1504 | 51 | * store the names of the generated artifacts for each package into package_artifacts |
ohrstrom@1504 | 52 | * store found dependencies to other packages into the supplied set package_dependencies |
ohrstrom@1504 | 53 | * store the public api for a package into the supplied set package_pubapis |
ohrstrom@1504 | 54 | * |
ohrstrom@1504 | 55 | * Any benign messages as a result of running the transform |
ohrstrom@1504 | 56 | * are written into stdout, and errors are written to stderr. |

ohrstrom@1504 | 58 | * The debug_level can be 0=silent (only warnings and errors) 1=normal 2=verbose 3 or greater=debug |

ohrstrom@1504 | 63 | * |
ohrstrom@1504 | 64 | * The transformer will only be called if some source in the package (or dependency) has |
ohrstrom@1504 | 65 | * a modified timestamp. Thus the transformer might get called with many sources, of which |
ohrstrom@1504 | 66 | * only one has changed. The transformer is allowed to regenerate all artifacts but |
ohrstrom@1504 | 67 | * a better transformer will only write those artifacts that need updating. |
ohrstrom@1504 | 68 | * |
ohrstrom@1504 | 69 | * However the transformer must verify that the existing artifacts really are there! |
ohrstrom@1504 | 70 | * and it must always update package_artifacts, package_dependencies, and package_pubapis correctly. |
ohrstrom@1504 | 71 | * This means that at least for Java source, it will always have to recompile the sources. |
ohrstrom@1504 | 72 | * |
ohrstrom@1504 | 73 | * The transformer is allowed to put files anywhere in the dest_root. |
ohrstrom@1504 | 74 | * An example of this is, can be the META-INF transformer that copy files |
ohrstrom@1504 | 75 | * below META-INF directories to the single META-INF directory below dest_root. |
ohrstrom@1504 | 76 | * |
ohrstrom@1504 | 77 | * False is returned if there was an error that prevented the transform. |
ohrstrom@1504 | 78 | * I.e. something was printed on stderr. |
ohrstrom@1504 | 79 | * |
ohrstrom@1504 | 80 | * If num_cores is set to a non-zero value. The transform should attempt to use no more than these |
ohrstrom@1504 | 81 | * number of threads for heavy work. |
