Method Detail
- getTargetType
```
public org.plasma.sdo.PlasmaType getTargetType()
```
- getSourceProp
```
public org.plasma.sdo.PlasmaProperty getSourceProp()
```
- getBaseType
```
public org.plasma.sdo.PlasmaType getBaseType()
```
  Calculates and returns whether the edges are local. If the opposite type is not bound (to a table), the type is stored in the local row and we write its sequences for this edge. Or if this type is not bound to a table, we also know its opposite edges must be local as well.
  
  Specified by:
  
  getBaseType in interface EdgeOperation
  
  Returns:
  
  whether the edges are local
- getSubType
```
public org.plasma.sdo.PlasmaType getSubType()
```
  Description copied from interface: EdgeOperation
  
  Returns the subtype or null if none exists
  
  Specified by:
  
  getSubType in interface EdgeOperation
  
  Returns:
  
  the subtype or null if none exists
- getPath
```
public String getPath()
```
  Description copied from interface: EdgeOperation
  
  Returns the traversal path (in XPath syntax) for the location of the collection relative to the root of the graph where the collection is instantiated.
  
  Specified by:
  
  getPath in interface EdgeOperation
  
  Returns:
  
  the traversal path (in XPath syntax) for the location of the collection relative to the root of the graph where the collection is instantiated.
- getSequences
```
public Set<Long> getSequences()
```
  Description copied from interface: EdgeOperation
  
  Returns the sequence identifiers for entities of the collection. Only used for local (non external) collections.
  
  Specified by:
  
  getSequences in interface EdgeOperation
  
  Returns:
  
  the sequence identifiers for entities of the collection.
- hasSequence
```
public boolean hasSequence(Long seq)
```
  Specified by:
  
  hasSequence in interface EdgeOperation
- getTable
```
public String getTable()
```
  Description copied from interface: EdgeOperation
  
  Returns the name of the table where the collection is instantiated. Only used for external (non local) collections.
  
  Specified by:
  
  getTable in interface EdgeOperation
  
  Returns:
  
  the name of the table where the collection is instantiated.
- getRowKeys
```
public List<DefaultEdgeOperation.KeyBytes> getRowKeys()
```
  Description copied from interface: EdgeOperation
  
  Returns the row keys for entities of the collection. Only used for external (non local) collections.
  
  Specified by:
  
  getRowKeys in interface EdgeOperation
  
  Returns:
  
  the row keys for entities of the collection.
- isExternal
```
public boolean isExternal()
```
  Description copied from interface: EdgeOperation
  
  Returns true if the collection is external, that is if the type for the collection is 'bound' to a physical table.
  
  Specified by:
  
  isExternal in interface EdgeOperation
  
  Returns:
  
  true if the collection is external.
- getCount
```
public long getCount()
```
  Description copied from interface: EdgeOperation
  
  Returns the (cached) count of members of the collection. Useful where only a count is needed.
  
  Specified by:
  
  getCount in interface EdgeOperation
  
  Returns:
  
  the cached count of members of the collection.
