After implementing a much more extensive Java native module than what currently exists in the tests, I found shortcomings. 1. You need to be able to pass multiple Java files. 2. Meson needs more information to better track the generated native headers. 3. Meson wasn't tracking the header files generated from inner classes. This new function should fix all the issues the old function had with room to grow should more functionality need to be added. What I implemented here in this new function is essentially what I have done in the Heterogeneous-Memory Storage Engine's Java bindings.

# Java Module
|
|
|
|
*(added in 0.60.0)*
|
|
|
|
## Functions
|
|
|
|
### `generate_native_header()`
|
|
|
|
*(deprecated in 0.62.0, use `generate_native_headers()`)*
|
|
|
|
This function will generate a header file for use in Java native module
|
|
development by reading the supplied Java file for `native` method declarations.
|
|
|
|
Keyword arguments:
|
|
|
|
- `package`: The [package](https://en.wikipedia.org/wiki/Java_package) of the
|
|
file. If left empty, Meson will assume that there is no package.
|
|
|
|
### `generate_native_headers()`
|
|
|
|
*(added in 0.62.0)*
|
|
|
|
This function will generate native header files for use in Java native module
|
|
development by reading the supplied Java files for `native` method declarations.
|
|
|
|
Keyword arguments:
|
|
|
|
- `classes`: The list of class names relative to the `package`, if it exists,
|
|
which contain `native` method declarations. Use `.` separated class names.
|
|
|
|
- `package`: The [package](https://en.wikipedia.org/wiki/Java_package) of the
|
|
file. If left empty, Meson will assume that there is no package.
|
|
|
|
Example:
|
|
|
|
```java
|
|
// Outer.java
|
|
|
|
package com.mesonbuild;
|
|
|
|
public class Outer {
|
|
private static native void outer();
|
|
|
|
public static class Inner {
|
|
private static native void inner();
|
|
}
|
|
}
|
|
```
|
|
|
|
With the above file, an invocation would look like the following:
|
|
|
|
```meson
|
|
java = import('java')
|
|
|
|
native_headers = java.generate_native_headers(
|
|
'Outer.java',
|
|
package: 'com.mesonbuild',
|
|
classes: ['Outer', 'Outer.Inner']
|
|
)
|
|
```
