A regular compilation unit, containing toplevel type, value, or function definitions.

This is the most commonly used type of compilation unit, and the basic “container” for your declarations.

Examples:

void run() {
    print("Hello, World!");
}

// end of example, start of next example

import ceylon.collection {
    SetMutator
}

MyPlugin myPlugin = MyPlugin(); // only instance

register
shared void registerMyPlugin(SetMutator<Plugin> registry)
    => registry.put(myPlugin);

Initializer
CompilationUnit(Declaration[] declarations, Import[] imports = [])
Parameters:
  • declarations

    The declarations in this compilation unit.

    (This attribute is empty for non-regular compilation units.)

  • imports = []

    The imports of this compilation unit.

Attributes
childrenSource Codeshared actual <Import|Declaration>[] children

The child nodes of this node.

Refines AnyCompilationUnit.children ultimately refines Node.children
declarationsSource Codeshared actual Declaration[] declarations

The declarations in this compilation unit.

(This attribute is empty for non-regular compilation units.)

hashSource Codeshared actual Integer hash

The hash value of the value, which allows the value to be an element of a hash-based set or key of a hash-based map. Implementations must respect the constraint that:

  • if x==y then x.hash==y.hash.

Therefore, a class which refines equals must also refine hash.

Refines Object.hash
importsSource Codeshared actual Import[] imports

The imports of this compilation unit.

moduleDescriptorSource Codeshared actual Null moduleDescriptor

Regular compilation units contain no module descriptor.

packageDescriptorSource Codeshared actual Null packageDescriptor

Regular compilation units contain no package descriptor.

Methods
copySource Codeshared CompilationUnit copy(Declaration[] declarations = ..., Import[] imports = ...)
Parameters:
  • declarations = this.declarations
  • imports = this.imports
equalsSource Codeshared actual Boolean equals(Object that)

Determine if two values are equal. Implementations should respect the constraints that:

  • if x===y then x==y (reflexivity),
  • if x==y then y==x (symmetry),
  • if x==y and y==z then x==z (transitivity).

Furthermore it is recommended that implementations ensure that if x==y then x and y have the same concrete class.

A class which explicitly refines equals() is said to support value equality, and the equality operator == is considered much more meaningful for such classes than for a class which simply inherits the default implementation of identity equality from Identifiable.

transformSource Codeshared actual Result transform<out Result>(Transformer<Result> transformer)

Transform this node with the given transformer by calling the appropriate transformX method on the transformer.

If you have a Node node that’s actually an LIdentifier instance, then the runtime will call LIdentifier.transform; therefore, this method is by nature narrowing. This means that if transformer is a NarrowingTransformer, calling node.transform(transformer) is equivalent to calling transformer.transformNode(node). On the other hand, if transformer is a WideningTransformer, then the two operations are very different.
