The dimeBlock class handles a BLOCK entity.
It cannot strictly be called an entity, as you will only find BLOCKs in the BLOCKS section, not in the ENTITIES section. But BLOCKs share a lot of attributes and functionality with "real" entities, so in DXFLIB, a BLOCK is called an entity.
dimeBlock::dimeBlock | ( | dimeMemHandler *const | memhandler | ) |
Constructor.
|
virtual |
Destructor.
|
inline |
Returns the base point of this block.
|
inline |
Sets the base point of this entity.
|
inline |
Returns the number of entities in this block.
|
inline |
Returns the entity at index idx.
void dimeBlock::insertEntity | ( | dimeEntity *const | entity, |
const int | idx = -1 |
||
) |
Inserts an entity in this block at position idx.
void dimeBlock::removeEntity | ( | const int | idx, |
const bool | deleteIt = true |
||
) |
Removes the entity at position idx. If deleteIt is true, and no memory handler is used, the entity will be deleted before returing from this method.
void dimeBlock::fitEntities | ( | ) |
Since a growable array is used to hold the entities, it might sometimes use more memory than absolutely needed. Call this method after you have finished modifying a block if you want to free that overhead memory.
|
inline |
Returns the name of this block (used by INSERT to reference the block).
|
inline |
Sets the name of this block. name Must be a static char pointer, or some pointer that will not be deleted before the block, as the text string will not be copied. It is best to avoid using this method. Use dimeModel::addBlock() instead.
|
virtual |
Must be implemented by subclasses to return a copy of the entity. model is the model the new entity should belong to.
Implements dimeEntity.
|
virtual |
Will return the value of the record with group code groupcode. false is returned if the record could not be found. Subclasses should overload this method if one or several records are stored in the class. If the groupcode queried is not stored internally, the subclass should call its parent's method.
Reimplemented from dimeEntity.
|
virtual |
Must be implemented by subclasses to return the entity name; e.g. POLYLINE, 3DFACE, etc.
Implements dimeEntity.
|
virtual |
This method reads a BLOCK entity from file.
Reimplemented from dimeEntity.
|
virtual |
This methods writes a BLOCK entity to file.
Reimplemented from dimeEntity.
|
virtual |
Must be implemented by all subclasses, and should return an unique id for that class.
Implements dimeBase.
|
virtual |
Returns the number of records in the record holder. Should be overloaded by subclasses which should count their records, and then call the parent's method. This method is used to precalculate the number of records to be written. Very useful when progress information is needed during write().
Reimplemented from dimeEntity.
|
protectedvirtual |
Must be overloaded by entities that directly supports a record type. During dimeRecordHolder::read(), dimeRecordHolder::setRecord and dimeRecordHolder::setRecords, this function is called for every record found, and it is up to the subclass if the record should be stored internally, or if a generic record should be created and stored in this superclass. A subclass should return true when it will handle the record, false otherwise. Default function does nothing, and returns false.
For entities, records with group codes 8 (layer name) and 62 (color number) are automatically handled by the dimeEntity class.
Reimplemented from dimeEntity.
|
protectedvirtual |
Used to find all forward references.
Reimplemented from dimeEntity.
|
protectedvirtual |
The traversal function used when dimeModel::traverseEntities() is called. Most entities use this default method, but some entities (INSERT, BUILD) will need to overload it.
Reimplemented from dimeEntity.
