API reference - Class LogEntryData

Notation used in Ruby API documentation

Module: db

Description: A generic log entry

This class is used for example by the device extractor (see NetlistDeviceExtractor) to keep errors or warnings that occurred during extraction of the devices.

Other classes also make use of this object to store errors, warnings or information. The log entry object features a severity (warning, error, info), a message, an optional category name and description (good for filtering if needed) and an optional DPolygon object for indicating some location or error marker. The original class used to be "NetlistDeviceExtractorError" which had been introduced in version 0.26. It was generalized and renamed in version 0.28.13 as it was basically not useful as a separate class.

Detailed description

Error

Signature: [static,const] Severity Error

Description: Specifies error severity (preferred action is stop)

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

Info

Signature: [static,const] Severity Info

Description: Specifies info severity (print if requested, otherwise silent)

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

NoSeverity

Signature: [static,const] Severity NoSeverity

Description: Specifies no particular severity (default)

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

Warning

Signature: [static,const] Severity Warning

Description: Specifies warning severity (log with high priority, but do not stop)

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

_const_cast

Signature: [const] LogEntryData 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 LogEntryData other)

Description: Assigns another object to self

category_description

Signature: [const] string category_description

Description: Gets the category description.

See category_name= for details about categories.

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

category_description=

Signature: void category_description= (string description)

Description: Sets the category description.

See category_name= for details about categories.

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

category_name

Signature: [const] string category_name

Description: Gets the category name.

See category_name= for more details.

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

category_name=

Signature: void category_name= (string name)

Description: Sets the category name.

The category name is optional. If given, it specifies a formal category name. Errors with the same category name are shown in that category. If in addition a category description is specified (see category_description), this description will be displayed as the title.

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

cell_name

Signature: [const] string cell_name

Description: Gets the cell name.

See cell_name= for details about this attribute.

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

cell_name=

Signature: void cell_name= (string cell_name)

Description: Sets the cell name.

The cell (or circuit) name specifies the cell or circuit the log entry is related to. If the log entry is an error or warning generated during device extraction, the cell name is the circuit the device should have appeared in.

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

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.

is_const_object?

Signature: [const] bool is_const_object?

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