| public void | parseContents(com.sun.org.apache.xalan.internal.xsltc.compiler.Parser parser)
_test = parser.parseExpression(this, "test", null);
// Ignore xsl:if when test is false (function-available() and
// element-available())

| public void | translate(com.sun.org.apache.xalan.internal.xsltc.compiler.util.ClassGenerator classGen, com.sun.org.apache.xalan.internal.xsltc.compiler.util.MethodGenerator methodGen)This method should never be called. An Otherwise object will explicitly
translate the "test" expression and and contents of this element.
final ErrorMsg msg = new ErrorMsg(ErrorMsg.STRAY_WHEN_ERR, this);
getParser().reportError(Constants.ERROR, msg);
|
| public com.sun.org.apache.xalan.internal.xsltc.compiler.util.Type | typeCheck(com.sun.org.apache.xalan.internal.xsltc.compiler.SymbolTable stable)Type-check this when element. The test should always be type checked,
while we do not bother with the contents if we know the test fails.
This is important in cases where the "test" expression tests for
the support of a non-available element, and the body contains
this non-available element.
// Type-check the test expression
if (_test.typeCheck(stable) instanceof BooleanType == false) {
_test = new CastExpr(_test, Type.Boolean);
}
// Type-check the contents (if necessary)
if (!_ignore) {
typeCheckContents(stable);
}
return Type.Void;
