API reference - Class DCellInstArray

!=

Signature: [const] bool != (const DCellInstArray other)

Description: Compares two arrays for inequality

<

Signature: [const] bool < (const DCellInstArray other)

Description: Compares two arrays for 'less'

The comparison provides an arbitrary sorting criterion and not specific sorting order. It is guaranteed that if an array a is less than b, b is not less than a. In addition, it a is not less than b and b is not less than a, then a is equal to b.

==

Signature: [const] bool == (const DCellInstArray other)

Description: Compares two arrays for equality

_const_cast

Signature: [const] DCellInstArray ptr _const_cast

Description: Returns a non-const reference to self.

Basically, this method allows turning a const object reference to a non-const one. This method is provided as last resort to remove the constness from an object. Usually there is a good reason for a const object reference, so using this method may have undesired side effects.

This method has been introduced in version 0.29.6.

_create

Signature: void _create

Description: Ensures the C++ object is created

Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created.

_destroy

Signature: void _destroy

Description: Explicitly destroys the object

Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing.

_destroyed?

Signature: [const] bool _destroyed?

Description: Returns a value indicating whether the object was already destroyed

This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself.

_is_const_object?

Signature: [const] bool _is_const_object?

Description: Returns a value indicating whether the reference is a const reference

This method returns true, if self is a const reference. In that case, only const methods may be called on self.

_manage

Signature: void _manage

Description: Marks the object as managed by the script side.

After calling this method on an object, the script side will be responsible for the management of the object. This method may be called if an object is returned from a C++ function and the object is known not to be owned by any C++ instance. If necessary, the script side may delete the object if the script's reference is no longer required.

Usually it's not required to call this method. It has been introduced in version 0.24.

_unmanage

Signature: void _unmanage

Description: Marks the object as no longer owned by the script side.

Calling this method will make this object no longer owned by the script's memory management. Instead, the object must be managed in some other way. Usually this method may be called if it is known that some C++ object holds and manages this object. Technically speaking, this method will turn the script's reference into a weak reference. After the script engine decides to delete the reference, the object itself will still exist. If the object is not managed otherwise, memory leaks will occur.

Usually it's not required to call this method. It has been introduced in version 0.24.

assign

Signature: void assign (const DCellInstArray other)

Description: Assigns another object to self

b

Signature: [const] DVector b

bbox

(1) Signature: [const] DBox bbox (const Layout layout, unsigned int layer_index)

Description: Gets the bounding box of the array with respect to one layer

'bbox' is the preferred synonym since version 0.28.

(2) Signature: [const] DBox bbox (const Layout layout)

Description: Gets the bounding box of the array

The bounding box incorporates all instances that the array represents. It needs the layout object to access the actual cell from the cell index.

bbox_per_layer

Signature: [const] DBox bbox_per_layer (const Layout layout, unsigned int layer_index)

Description: Gets the bounding box of the array with respect to one layer

Use of this method is deprecated. Use bbox instead

The bounding box incorporates all instances that the array represents. It needs the layout object to access the actual cell from the cell index.

'bbox' is the preferred synonym since version 0.28.

cell=

Signature: void cell= (Cell ptr cell)

Description: Sets the cell this instance refers to

This is a convenience method and equivalent to 'cell_index = cell.cell_index()'. There is no getter for the cell pointer because the CellInstArray object only knows about cell indexes.

This convenience method has been introduced in version 0.28.

Python specific notes:
The object exposes a writable attribute 'cell'. This is the setter.

cell_index

Signature: [const] unsigned int cell_index

cplx_trans

Signature: [const] DCplxTrans cplx_trans

Description: Gets the complex transformation of the first instance in the array

This method is always applicable, compared to trans, since simple transformations can be expressed as complex transformations as well.

Python specific notes:
The object exposes a readable attribute 'cplx_trans'. This is the getter.

cplx_trans=

Signature: void cplx_trans= (const DCplxTrans trans)

Description: Sets the complex transformation of the instance or the first instance in the array

Python specific notes:
The object exposes a writable attribute 'cplx_trans'. This is the setter.

destroy

Signature: void destroy

Description: Explicitly destroys the object

Use of this method is deprecated. Use _destroy instead

Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing.

destroyed?

Signature: [const] bool destroyed?

Description: Returns a value indicating whether the object was already destroyed

Use of this method is deprecated. Use _destroyed? instead

each_cplx_trans

Signature: [const,iter] DCplxTrans each_cplx_trans

Description: Gets the complex transformations represented by this instance

For a single instance, this iterator will deliver the single, complex transformation. For array instances, the iterator will deliver each complex transformation of the expanded array. This iterator is a generalization of each_trans for general complex transformations.

each_trans

Signature: [const,iter] DTrans each_trans

Description: Gets the simple transformations represented by this instance

For a single instance, this iterator will deliver the single, simple transformation. For array instances, the iterator will deliver each simple transformation of the expanded array.
