Method Detail

createTree

public ITree createTree()

Creates a new tree that is not associated with a store.

createTree

public ITree createTree(String options)

Creates a new tree that is not associated with a store.

createTree

public ITree createTree(String storeName,
                        String storeType)
                 throws IllegalArgumentException,
                        RuntimeException

Creates a new tree and associates it with a store.

The definition of the various modes than can be specified are:

• AUTO default case: create of store does not exist
• CREATE: Create a new file (throws an exception if already exists)
• RECREATE: overwrite file if existing
• READONLY: open in read only mode
• UPDATE: read/write mode, overwriting modified objects.

Parameters:

storeName - The name of the store, if empty (""), the tree is created in memory and therefore will not be associated with a file.

storeType - Implementation specific string, may control store type

Throws:

RuntimeException - if the store already exists

IllegalArgumentException
