All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`org.plasma.sdo.PlasmaType`	`getBaseType()` Returns the base type of the collection.
`long`	`getCount()` Returns the (cached) count of members of the collection.
`String`	`getPath()` 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.
`List<DefaultEdgeOperation.KeyBytes>`	`getRowKeys()` Returns the row keys for entities of the collection.
`Set<Long>`	`getSequences()` Returns the sequence identifiers for entities of the collection.
`org.plasma.sdo.PlasmaType`	`getSubType()` Returns the subtype or null if none exists
`String`	`getTable()` Returns the name of the table where the collection is instantiated.
`boolean`	`hasSequence(Long seq)`
`boolean`	`isExternal()` Returns true if the collection is external, that is if the type for the collection is 'bound' to a physical table.

- Method Detail
  - getBaseType
```
org.plasma.sdo.PlasmaType getBaseType()
```
    Returns the base type of the collection. Individual collection members by contain instances of subclasses of the base type.
    
    Returns:
    
    the base type of the collection.
  - getPath
```
String getPath()
```
    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.
    
    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
```
Set<Long> getSequences()
```
    Returns the sequence identifiers for entities of the collection. Only used for local (non external) collections.
    
    Returns:
    
    the sequence identifiers for entities of the collection.
  - hasSequence
```
boolean hasSequence(Long seq)
```
  - getSubType
```
org.plasma.sdo.PlasmaType getSubType()
```
    Returns the subtype or null if none exists
    
    Parameters:
    
    sequence - the sequence
    
    Returns:
    
    the subtype or null if none exists
  - getTable
```
String getTable()
```
    Returns the name of the table where the collection is instantiated. Only used for external (non local) collections.
    
    Returns:
    
    the name of the table where the collection is instantiated.
  - getRowKeys
```
List<DefaultEdgeOperation.KeyBytes> getRowKeys()
```
    Returns the row keys for entities of the collection. Only used for external (non local) collections.
    
    Returns:
    
    the row keys for entities of the collection.
  - isExternal
```
boolean isExternal()
```
    Returns true if the collection is external, that is if the type for the collection is 'bound' to a physical table.
    
    Returns:
    
    true if the collection is external.
  - getCount
```
long getCount()
```
    Returns the (cached) count of members of the collection. Useful where only a count is needed.
    
    Returns:
    
    the cached count of members of the collection.
