BOOL AttrTypeSet::AddToSet (  List &  Attributes  )  [virtual]

Adds the Types of all attributes in the Attributes list. Author: Simon_Maneggio (Xara Group Ltd) <camelotdev@xara.com> Date: 12/5/95 Parameters: A  list of attributes (each item must be a NodeAttributePtrItem) [INPUTS] Returns: FALSE if we run out of memory. See also: AttrTypeSet::InSet AttrTypeSet::CopySet Definition at line 6427 of file node.cpp. { NodeAttributePtrItem* pAttrItem = (NodeAttributePtrItem*)(Attributes.GetHead()); NodeAttribute* pAttr; while (pAttrItem) { pAttr = pAttrItem->NodeAttribPtr; ERROR3IF(!pAttr, "Should be an attribute"); if (!AddToSet(pAttr->GetAttributeType())) { return FALSE; } pAttrItem = (NodeAttributePtrItem*)(Attributes.GetNext(pAttrItem)); } return TRUE; }

BOOL AttrTypeSet::AddToSet (  CCRuntimeClass *  AttrType  )  [virtual]

Adds AttrType to the set. Author: Simon_Maneggio (Xara Group Ltd) <camelotdev@xara.com> Date: 12/5/95 Returns: FALSE if we run out of memory See also: AttrTypeSet::InSet AttrTypeSet::CopySet Definition at line 6386 of file node.cpp. { ERROR3IF(AttrType == NULL, "AddToSet: AttrType is NULL"); // Determine if the AttrType is already in the set AttrTypeItem* pAttrType = (AttrTypeItem*) GetHead(); while (pAttrType != NULL) { if (pAttrType->AttributeType == AttrType) { return TRUE; // Already in set so return } pAttrType = (AttrTypeItem*) GetNext(pAttrType); } // The attribute type is not in the set so let's add it pAttrType = new AttrTypeItem; if (!pAttrType) return FALSE; // out of memory (error has been set) pAttrType->AttributeType = AttrType; AddHead(pAttrType); // Add attribute to the head of the list return TRUE; }

AttrTypeSet * AttrTypeSet::CopySet (   )

Makes a copy of the attribute type set. Author: Simon_Maneggio (Xara Group Ltd) <camelotdev@xara.com> Date: 15/5/95 Parameters: -  [INPUTS] -  [OUTPUTS] Returns: A copy of the set, or NULL if we run out of memory Errors: - See also: AttrTypeSet::AddToSet AttrTypeSet::InSet Definition at line 6460 of file node.cpp. { AttrTypeSet* pSetCopy; pSetCopy = new AttrTypeSet; if (!pSetCopy) return NULL; // Out of memory // Copy each item in turn AttrTypeItem* pItemCopy; AttrTypeItem* pCurrent = (AttrTypeItem*)GetHead(); while (pCurrent) { pItemCopy = new AttrTypeItem; if (!pItemCopy) { // Tidyup pSetCopy->DeleteAll(); delete pSetCopy; return NULL; } pItemCopy->AttributeType = pCurrent->AttributeType; pSetCopy->AddTail(pItemCopy); pCurrent = (AttrTypeItem*)GetNext(pCurrent); } return pSetCopy; }

BOOL AttrTypeSet::InSet (  CCRuntimeClass *  AttrType  )

To determine if AttrType is in the set. Author: Simon_Maneggio (Xara Group Ltd) <camelotdev@xara.com> Date: 15/5/95 Parameters: AttrType,:  The type of an attribute [INPUTS] -  [OUTPUTS] Returns: TRUE if AttrType is in the set Errors: - See also: AttrTypeSet::CopySet AttrTypeSet::AddToSet Definition at line 6502 of file node.cpp. { AttrTypeItem* pCurrent = (AttrTypeItem*)GetHead(); while (pCurrent) { if (pCurrent->AttributeType == AttrType) return TRUE; pCurrent = (AttrTypeItem*)GetNext(pCurrent); } return FALSE; }
