/** |

|
|
|
* Class Substitute |
|
20
|
|
|
* The optional cs:substitute element, which must be included as the last child element of cs:names, adds substitution |
|
21
|
|
|
* in case the name variables specified in the parent cs:names element are empty. The substitutions are specified as |
|
22
|
|
|
* child elements of cs:substitute, and must consist of one or more rendering elements (with the exception of cs:layout). |
|
23
|
|
|
* |
|
24
|
|
|
* A shorthand version of cs:names without child elements, which inherits the attributes values set on the cs:name and |
|
25
|
|
|
* cs:et-al child elements of the original cs:names element, may also be used. |
|
26
|
|
|
* |
|
27
|
|
|
* If cs:substitute contains multiple child elements, the first element to return a non-empty result is used for |
|
28
|
|
|
* substitution. Substituted variables are suppressed in the rest of the output to prevent duplication. An example, |
|
29
|
|
|
* where an empty “author” name variable is substituted by the “editor” name variable, or, when no editors exist, by |
|
30
|
|
|
* the “title” macro: |
|
31
|
|
|
* <pre> |
|
32
|
|
|
* <macro name="author"> |
|
33
|
|
|
* <names variable="author"> |
|
34
|
|
|
* <substitute> |
|
35
|
|
|
* <names variable="editor"/> |
|
36
|
|
|
* <text macro="title"/> |
|
37
|
|
|
* </substitute> |
|
38
|
|
|
* </names> |

This check looks for calls to methods that do not seem to exist on a given type. It looks for the method on the type itself as well as in inherited classes or implemented interfaces.
This is most likely a typographical error or the method has been renamed.
