Notation used in Ruby API documentation

Module: db

Description: Texts (a collection of texts)

Class hierarchy: Texts » ShapeCollection

Text objects are useful as labels for net names, to identify certain regions and to specify specific locations in general. Text collections provide a way to store - also in a hierarchical fashion - and manipulate a collection of text objects.

Text objects can be turned into polygons by creating small boxes around the texts (polygons). Texts can also be turned into dot-like edges (edges). Texts can be filtered by string, either by matching against a fixed string (with_text) or a glob-style pattern (with_match).

Text collections can be filtered geometrically against a polygon Region using interacting or non-interacting. Vice versa, texts can be used to select polygons from a Region using pull_interacting.

Beside that, text collections can be transformed, flattened and combined, similar to EdgePairs.

This class has been introduced in version 0.27.

Detailed description

&

Signature: [const] Texts & (const Region other)

Description: Returns the texts from this text collection which are inside or on the edge of polygons from the given region

Returns:A new text collection containing the texts inside or on the edge of polygons from the region

+

Signature: [const] Texts + (const Texts other)

Description: Returns the combined text collection of self and the other one

Returns:The resulting text collection

This operator adds the texts of the other collection to self and returns a new combined set.

The 'join' alias has been introduced in version 0.28.12.

+=

Signature: Texts += (const Texts other)

Description: Adds the texts of the other text collection to self

Returns:The text collection after modification (self)

This operator adds the texts of the other collection to self.

Note that in Ruby, the '+=' operator actually does not exist, but is emulated by '+' followed by an assignment. This is less efficient than the in-place operation, so it is recommended to use 'join_with' instead.

The 'join_with' alias has been introduced in version 0.28.12.

-

Signature: [const] Texts - (const Region other)

Description: Returns the texts from this text collection which are not inside or on the edge of polygons from the given region

Returns:A new text collection containing the texts not inside or on the edge of polygons from the region

[]

Signature: [const] const Text ptr [] (unsigned long n)

Description: Returns the nth text

This method returns nil if the index is out of range. It is available for flat texts only - i.e. those for which has_valid_texts? is true. Use flatten to explicitly flatten an text collection.

The each iterator is the more general approach to access the texts.

_const_cast

Signature: [const] Texts 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 Texts other)

Description: Assigns another object to self

bbox

Signature: [const] Box bbox

Description: Return the bounding box of the text collection

The bounding box is the box enclosing all origins of all texts.

clear

Signature: void clear

Description: Clears the text collection

count

Signature: [const] unsigned long count

Description: Returns the (flat) number of texts in the text collection

The count is computed 'as if flat', i.e. texts inside a cell are multiplied by the number of times a cell is instantiated.

Starting with version 0.27, the method is called 'count' for consistency with Region. 'size' is still provided as an alias.

Python specific notes:
This method is also available as 'len(object)'.

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.

data_id

Signature: [const] unsigned long data_id

Description: Returns the data ID (a unique identifier for the underlying data storage)

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.

disable_progress

Signature: void disable_progress

Description: Disable progress reporting

Calling this method will disable progress reporting. See enable_progress.

Description: Returns each text of the text collection

Python specific notes:
This method enables iteration of the object.

edges

Signature: [const] Edges edges

Description: Returns dot-like edges for the texts

Returns:An edge collection containing the individual, dot-like edges

enable_progress

Signature: void enable_progress (string label)

Description: Enable progress reporting

After calling this method, the text collection will report the progress through a progress bar while expensive operations are running. The label is a text which is put in front of the progress bar. Using a progress bar will imply a performance penalty of a few percent typically.

enable_properties

Signature: void enable_properties

Description: Enables properties for the given container.

This method has an effect mainly on original layers and will import properties from such layers. By default, properties are not enabled on original layers. Alternatively you can apply filter_properties or map_properties to enable properties with a specific name key.

This method has been introduced in version 0.28.4.

extents

(1) Signature: [const] Region extents (int d = 1)

Description: Returns a region with the enlarged bounding boxes of the texts

Text bounding boxes are point-like boxes which vanish unless an enlargement of >0 is specified. The bounding box is centered at the text's location. The boxes will not be merged, so it is possible to determine overlaps of these boxes for example.

(2) Signature: [const] Region extents (int dx, int dy)

Description: Returns a region with the enlarged bounding boxes of the texts

This method acts like the other version of extents, but allows giving different enlargements for x and y direction.

Signature: [const] Region pull_interacting (const Region other)

Description: Returns all polygons of "other" which are including texts of this text set

Returns:The region after the polygons have been selected (from other)

The "pull_..." method is similar to "select_..." but works the opposite way: it selects shapes from the argument region rather than self. In a deep (hierarchical) context the output region will be hierarchically aligned with self, so the "pull_..." method provide a way for re-hierarchization.

Merged semantics applies for the polygon region.

Python specific notes:
This method is also available as 'len(object)'.

swap

Signature: void swap (Texts other)
