| <h2><a name="Conditions">Conditions</a></h2> |
| |
| <p>These are the nested elements that can be used as conditions in the |
| <a href="condition.html"><code><condition></code></a> and |
| <a href="waitfor.html"><code><waitfor></code></a> tasks.</p> |
| |
| <h4>not</h4> |
| <p>The <code><not></code> element expects exactly one other |
| condition to be nested into this element, negating the result of the |
| condition. It doesn't have any attributes and accepts all nested |
| elements of the condition task as nested elements as well.</p> |
| |
| <h4>and</h4> <p> |
| The <code><and></code> element doesn't have any attributes and |
| accepts an arbitrary number of conditions as nested elements - all |
| nested elements of the condition task are supported. This condition |
| is true if all of its contained conditions are, conditions will be |
| evaluated in the order they have been specified in the build file.</p> |
| <p>The <code><and></code> condition has the same shortcut |
| semantics as the Java && operator, as soon as one of the |
| nested conditions is false, no other condition will be evaluated.</p> |
| |
| <h4>or</h4> <p> |
| The <code><or></code> element doesn't have any attributes and |
| accepts an arbitrary number of conditions as nested elements - all |
| nested elements of the condition task are supported. This condition |
| is true if at least one of its contained conditions is, conditions |
| will be evaluated in the order they have been specified in the build |
| file.</p> <p>The <code><or></code> condition has the same |
| shortcut semantics as the Java || operator, as soon as one of the |
| nested conditions is true, no other condition will be evaluated.</p> |
| |
| <h4>available</h4> |
| <p>This condition is identical to the <a |
| href="available.html">Available</a> task, all attributes and nested |
| elements of that task are supported, the property and value attributes |
| are redundant and will be ignored.</p> |
| |
| <h4>uptodate</h4> |
| <p>This condition is identical to the <a |
| href="uptodate.html">Uptodate</a> task, all attributes and nested |
| elements of that task are supported, the property and value attributes |
| are redundant and will be ignored.</p> |
| |
| <h4>os</h4> |
| <p>Test whether the current operating system is of a given type. Each |
| defined attribute is tested and the result is true only if <i>all</i> |
| the tests succeed. |

| <h4>filesmatch</h4> |
| <p>Test two files for matching. Nonexistence of either file results in "false". |
| This test does a byte for byte comparision, so test time scales with |
| byte size. NB: if the files are different sizes , one of them is missing |
| or the filenames match the answer is so obvious the detailed test is omitted. |
