Detailed Description

This class implements Iterator objects that traverse entries in OdDbBlockTableRecord objects in an OdDbDatabase instance.

Remarks

Instances are returned by OdDbBlockTableRecord::newIterator().

Member Function Documentation

id()

virtual OdDbObjectId OdDbBlockIterator::id ( ) const

pure virtual

Returns the Object ID of the record currently referenced by this Iterator object.

newBlockIterator()

static OdDbBlockIteratorPtr OdDbBlockIterator::newBlockIterator ( const OdDbBlockTableRecord *  pBtr )

static

Returns an Iterator object that can be used to traverse the specified Block Table Record.

Parameters

pBtr	[in] Pointer the Block Table Record to traverse.

newCompositeIterator()

static OdDbBlockIteratorPtr OdDbBlockIterator::newCompositeIterator ( const OdDbBlockTableRecord *  pBtr, const OdArray< OdSmartPtr< OdDbFilter > > &  filters  )

static

Returns an Iterator object that can be used to traverse queries defined by an array of OdDbFilter objects applied to the specified Block Table Record.

Parameters

pBtr	[in] Pointer the Block Table Record to traverse.
filters	[in] Array of pointers to filter objects.

newFilteredIterator()

static OdDbBlockIteratorPtr OdDbBlockIterator::newFilteredIterator ( const OdDbBlockTableRecord *  pBtr, const OdDbFilter *  pFilter  )

static

Returns an Iterator object that can be used to traverse queries defined by OdDbFilter objects applied to the specified Block Table Record.

Parameters

pBtr	[in] Pointer the Block Table Record to traverse.
pFilter	[in] Pointer to the filter.

next()

virtual OdDbObjectId OdDbBlockIterator::next ( )

pure virtual

Returns the Object ID of the next object, and increments this Iterator object.

ODRX_DECLARE_MEMBERS()

OdDbBlockIterator::ODRX_DECLARE_MEMBERS

(

OdDbBlockIterator

)

seek()

virtual bool OdDbBlockIterator::seek ( OdDbObjectId  objectId )

pure virtual

Positions this Iterator object at the specified record.

Parameters

objectId

[in] Object ID of the record.

Returns

Returns true if and only if successful.

start()

virtual void OdDbBlockIterator::start ( )

pure virtual

Sets this Iterator object to reference the OdDbBlock that it would normally return first.

Remarks

Allows multiple traversals of the Iterator list.
