EOLANG Wrapper for java objects.

How-to

Create a java object inside EO program

+alias org.eolang.jvm-bridge.native-object

# Without constructor parameters
native-object "java.lang.StringBuilder"

# With constructor parameters
native-object
  "java.math.BigInteger"
  "8"

Call java object methods

+alias org.eolang.jvm-bridge.native-object

native-object > builder 
  "java.lang.StringBuilder"

builder.append "text"
builder.to-string

All methods of an object are translated to kebab-case (for example, toString turns into to-string)

Nullability

A native-object can be null (nowhere to go, it's java), in this case it will have is-null attribute, being TRUE. If the object is not null, is-null is FALSE.

If an object is null, dataization will throw NullPointerException, in other cases it will call toString of the java object.
