Detailed Description

read-only access to the children of an Object, as returned by Object.constChildren()

Object stores its children as std::shared_ptr<Object>, and a const Object cannot hand them out directly without either dropping constness or copying the whole vector. This class solves that: it is a lightweight non-owning view on the object's children, which produces std::shared_ptr<const Object> on the fly. Typical use:

for ( const auto & child : obj.constChildren() )
    processRecursively( *child );

It is also indexable, so a plain loop works too:

for ( size_t i = 0; i < obj.constChildren().size(); ++i )
    process( *obj.constChildren()[i] );

The view refers to the object's own storage, so use it as a temporary and do not store it: it is invalidated by anything that adds, removes or reorders the object's children, exactly like an iterator of the underlying vector. Generated from class MR::ConstChildren.

Instances created here own their C++ objects, see CppObject.

Constructor & Destructor Documentation

ConstChildren() [1/3]

meshlib.ConstChildren.ConstChildren	(	java.lang.foreign.MemorySegment	ptr,
		boolean	owned,
		java.lang.Object	owner )

Wraps a pointer from the C bindings. If owned, the object is destroyed when the wrapper dies. owner is kept alive as long as this wrapper is. Not for normal use.

ConstChildren() [2/3]

meshlib.ConstChildren.ConstChildren

(

meshlib.ConstChildren

_other

)

Generated from constructor MR::ConstChildren::ConstChildren. The reference to things referred to by the parameter _other (if any) might be preserved in the constructed object.

Calls MR_ConstChildren_ConstructFromAnother().

ConstChildren() [3/3]

meshlib.ConstChildren.ConstChildren

(

meshlib.std_vector_std_shared_ptr_MR_Object

children

)

Generated from constructor MR::ConstChildren::ConstChildren. The reference to the parameter children might be preserved in the constructed object.

Calls MR_ConstChildren_Construct().

meshlib.ConstChildren_Iterator meshlib.ConstChildren.begin

(

)

Generated from method MR::ConstChildren::begin. The reference to this object might be preserved in the return value.

empty()

boolean meshlib.ConstChildren.empty

(

)

Generated from method MR::ConstChildren::empty.

Calls MR_ConstChildren_empty().

end()

meshlib.ConstChildren_Iterator meshlib.ConstChildren.end

(

)

Generated from method MR::ConstChildren::end. The reference to this object might be preserved in the return value.

Calls MR_ConstChildren_end().
