API reference - Class NetlistSpiceWriterDelegate

Notation used in Ruby API documentation

Module: db

Description: Provides a delegate for the SPICE writer for doing special formatting for devices

Supply a customized class to provide a specialized writing scheme for devices. You need a customized class if you want to implement special devices or you want to use subcircuits rather than the built-in devices.

See NetlistSpiceWriter for more details.

This class has been introduced in version 0.26.

Public constructors

new NetlistSpiceWriterDelegate ptrnewCreates a new object of this class

Detailed description

_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 NetlistSpiceWriterDelegate other)

Description: Assigns another object to self

create

Signature: void create

Description: Ensures the C++ object is created

Use of this method is deprecated. Use _create instead

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

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

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.

dup

Signature: [const] new NetlistSpiceWriterDelegate ptr dup

Description: Creates a copy of self

Python specific notes:
This method also implements '__copy__' and '__deepcopy__'.

emit_comment

Signature: [const] void emit_comment (string comment)

Description: Writes the given comment into the file

emit_line

Signature: [const] void emit_line (string line)

Description: Writes the given line into the file

format_name

Signature: [const] string format_name (string name)

Description: Formats the given name in a SPICE-compatible way

is_const_object?

Signature: [const] bool is_const_object?

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

Use of this method is deprecated. Use _is_const_object? instead

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

net_to_string

Signature: [const] string net_to_string (const Net ptr net)

Description: Gets the node ID for the given net

The node ID is a numeric string instead of the full name of the net. Numeric IDs are used within SPICE netlist because they are usually shorter.

new

Signature: [static] new NetlistSpiceWriterDelegate ptr new

Description: Creates a new object of this class

Python specific notes:
This method is the default initializer of the object.

write_device

Signature: [virtual,const] void write_device (Device device)

Description: Inserts a text for the given device

Reimplement this method to write the given device in the desired way. The default implementation will utilize the device class information to write native SPICE elements for the devices.

write_device_intro

Signature: [virtual,const] void write_device_intro (DeviceClass device_class)

Description: Inserts a text for the given device class

Reimplement this method to insert your own text at the beginning of the file for the given device class

write_header

Signature: [virtual,const] void write_header

Description: Writes the text at the beginning of the SPICE netlist

Reimplement this method to insert your own text at the beginning of the file
