Class SchemaManager

java.lang.Object
  com.jcorporate.expresso.services.test.SchemaManager

public class SchemaManager

extends Object

This class reference counts references to various Schema objects. When a reference count drops to zero, the schema is deleted. [If it's not marked read only] If it is marked readonly, then the schema is created, but not deleted. [Makes for much faster checking when running unit tests on, say, a single controller]

public SchemaManager()

Method Detail

addReference

public static void addReference(Schema s)

Add a reference to a schema. Create the schema if no previous reference

Parameters:

s - The Schema to reference

addReference

public static void addReference(Schema s,
                                boolean forceNoCreate)

Add a reference to a schema. Create the schema if no previous reference

Parameters:

s - The Schema to reference

forceNoCreate - Set to true if you just want a reference added, but no schema created. This is used if DBToolTests are being run in the test suite.

addReadOnlyReference

public static void addReadOnlyReference(Schema s)

Adds a schema reference that is not removed when the count goes to zero because it is a read only schema. You can undo this 'read-onliness' by calling forceSchemaDelete() which will remove the read only flags for this schema. Note that if any other reference is added for this schema, then if it's a non-readonly reference, than the schema will be deleted as usual.

Parameters:

s - the Schema to add

removeReference

public static void removeReference(Schema s)

Reduces the reference count to Schema s. Deletes the schema if the reference count is reduced to zero.

Parameters:

s - the Schema to remove a reference.

forceSchemaDelete

public static void forceSchemaDelete(Schema s)

Forces the schema deletion even if the schema is marked "read only"

Parameters:

s - the schema to force a delete

forceAllSchemaDelete

public static void forceAllSchemaDelete()
