API reference - Class LayerInfo

Notation used in Ruby API documentation

Description: A structure encapsulating the layer properties

• Public constructors
• Public methods
• Detailed description

The layer properties describe how a layer is stored in a GDSII or OASIS file for example.

Public constructors

Public methods

Detailed description

[const] bool !=(const LayerInfo b)

Description: Compare two layer info objects

This method was added in version 0.18.

[const] bool ==(const LayerInfo b)

Description: Compare two layer info objects

This method was added in version 0.18.

[const] void assign(const LayerInfo other)

Description: Assign the contents of another object to self

This method assigns the contents of another object to self. This is a deep copy that does not only copy the reference but the actual content.

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.

[const] int datatype

Description: Gets the datatype

void datatype=(int datatype)

Description: Set the datatype

void destroy

Description: Explicitly destroy the object

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

[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.

[const] LayerInfo dup

Description: Creates a copy of self

[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.

[const] bool is_equivalent?(const LayerInfo b)

Description: Equivalence of two layer info objects

First, layer and datatype are compared. The name is of second order and used only if no layer or datatype is given. This is basically a weak comparison that reflects the search preferences.

This method was added in version 0.18.

[const] bool is_named?

Description: Returns true, if the layer is purely specified by name.

This method was added in version 0.18.

[const] int layer

Description: Gets the layer number

void layer=(int layer)

Description: Sets the layer number

[const] string name

Description: Gets the layer name

void name=(string name)

Description: Set the layer name

The name is set on OASIS input for example, if the layer has a name.

[static] new LayerInfo new

Description: The default constructor.

Creates a default LayerInfo object.

This method was added in version 0.18.

[static] new LayerInfo new(int layer,int datatype)

Description: The constructor for a layer/datatype pair.

Creates a LayerInfo object representing a layer and datatype.

This method was added in version 0.18.

[static] new LayerInfo new(string name)

Description: The constructor for a named layer.

Creates a LayerInfo object representing a named layer.

This method was added in version 0.18.

[static] new LayerInfo new(int layer,int datatype,string name)

Description: The constructor for a named layer with layer and datatype.

Creates a LayerInfo object representing a named layer with layer and datatype.

This method was added in version 0.18.

[const] string to_s

Description: Convert the layer info object to a string

This method was added in version 0.18.
