#include <DDF_Transaction.hxx>
Public Member Functions | |
| DDF_Transaction () | |
| Creates an empty transaction context, unable to be opened. | |
| DDF_Transaction (const occ::handle< TDF_Data > &aDF) | |
| Creates a transaction context on <aDF>, ready to be opened. | |
| int | Open () |
| If not yet done, opens a new transaction on <myDF>. Returns the index of the just opened transaction. | |
| occ::handle< TDF_Delta > | Commit (const bool withDelta=false) |
| Commits the transactions until AND including the current opened one. | |
| void | Abort () |
| Aborts the transactions until AND including the current opened one. | |
| ~DDF_Transaction () override | |
| occ::handle< TDF_Data > | Data () const |
| Returns the Data from TDF. | |
| int | Transaction () const |
| Returns the number of the transaction opened by <me>. | |
| bool | IsOpen () const |
| Returns true if the transaction is open. | |
 Public Member Functions inherited from Standard_Transient | |
| Standard_Transient () | |
| Empty constructor. | |
| Standard_Transient (const Standard_Transient &) | |
| Copy constructor – does nothing. | |
| Standard_Transient & | operator= (const Standard_Transient &) |
| Assignment operator, needed to avoid copying reference counter. | |
| virtual | ~Standard_Transient ()=default |
| Destructor must be virtual. | |
| virtual const opencascade::handle< Standard_Type > & | DynamicType () const |
| Returns a type descriptor about this object. | |
| bool | IsInstance (const opencascade::handle< Standard_Type > &theType) const |
| Returns a true value if this is an instance of Type. | |
| bool | IsInstance (const char *const theTypeName) const |
| Returns a true value if this is an instance of TypeName. | |
| bool | IsKind (const opencascade::handle< Standard_Type > &theType) const |
| Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism. | |
| bool | IsKind (const char *const theTypeName) const |
| Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism. | |
| Standard_Transient * | This () const |
| Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero. | |
| int | GetRefCount () const noexcept |
| Get the reference counter of this object. | |
| void | IncrementRefCounter () noexcept |
| Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations. | |
| int | DecrementRefCounter () noexcept |
| Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement. | |
| virtual void | Delete () const |
| Memory deallocator for transient classes. | |
Additional Inherited Members | |
| Public Types inherited from Standard_Transient | |
| typedef void | base_type |
| Returns a type descriptor about this object. | |
| Static Public Member Functions inherited from Standard_Transient | |
| static constexpr const char * | get_type_name () |
| Returns a type descriptor about this object. | |
| static const opencascade::handle< Standard_Type > & | get_type_descriptor () |
| Returns type descriptor of Standard_Transient class. | |
This class encapsulates TDF_Transaction.
| DDF_Transaction::DDF_Transaction | ( | ) |
Creates an empty transaction context, unable to be opened.
| DDF_Transaction::DDF_Transaction | ( | const occ::handle< TDF_Data > & | aDF | ) |
Creates a transaction context on <aDF>, ready to be opened.
|
inlineoverride |
| void DDF_Transaction::Abort | ( | ) |
Aborts the transactions until AND including the current opened one.
| occ::handle< TDF_Delta > DDF_Transaction::Commit | ( | const bool | withDelta = false | ) |
Commits the transactions until AND including the current opened one.
| occ::handle< TDF_Data > DDF_Transaction::Data | ( | ) | const |
Returns the Data from TDF.
| bool DDF_Transaction::IsOpen | ( | ) | const |
Returns true if the transaction is open.
| int DDF_Transaction::Open | ( | ) |
If not yet done, opens a new transaction on <myDF>. Returns the index of the just opened transaction.
It raises DomainError if the transaction is already open, and NullObject if there is no current Data framework.
| int DDF_Transaction::Transaction | ( | ) | const |
Returns the number of the transaction opened by <me>.
