| 57 | /** |
| 58 | * The FilerImplementation class must maintain a number of |
| 59 | * constraints. First, multiple attempts to open the same path within |
| 60 | * the same invocation of the tool results in an IOException being |
| 61 | * thrown. For example, trying to open the same source file twice: |
| 62 | * |
| 63 | * <pre> |
| 64 | * createSourceFile("foo.Bar") |
| 65 | * ... |
| 66 | * createSourceFile("foo.Bar") |
| 67 | * </pre> |
| 68 | * |
| 69 | * is disallowed as is opening a text file that happens to have |
| 70 | * the same name as a source file: |
| 71 | * |
| 72 | * <pre> |
| 73 | * createSourceFile("foo.Bar") |
| 74 | * ... |
| 75 | * createTextFile(SOURCE_TREE, "foo", new File("Bar"), null) |
| 76 | * </pre> |
| 77 | * |
| 78 | * <p>Additionally, creating a source file that corresponds to an |
| 79 | * already created class file (or vice versa) also results in an |
| 80 | * IOException since each type can only be created once. However, if |
| 81 | * the Filer is used to create a text file named *.java that happens |
| 82 | * to correspond to an existing class file, a warning is *not* |
| 83 | * generated. Similarly, a warning is not generated for a binary file |
| 84 | * named *.class and an existing source file. |
| 85 | * |
| 86 | * <p>The reason for this difference is that source files and class |
| 87 | * files are registered with the tool and can get passed on as |
| 88 | * declarations to the next round of processing. Files that are just |
| 89 | * named *.java and *.class are not processed in that manner; although |
| 90 | * having extra source files and class files on the source path and |
| 91 | * class path can alter the behavior of the tool and any final |
| 92 | * compile. |
| 93 | * |
| 94 | * <p><b>This is NOT part of any API supported by Sun Microsystems. |
| 95 | * If you write code that depends on this, you do so at your own risk. |
