 javax.media.jai.FactoryCache
| FactoryCache | | class FactoryCache (Code) | | A class to manage the various instances of a descriptor factory.
This also manages preferences between factory instances for
a specified descriptor/product.
since:
JAI 1.1 |
| Method Summary | |
| void | addFactory(String descriptorName, String productName, Object factoryInstance)
Add a factory instance to this factory. | | void | clearPreferences(String descriptorName, String productName)
Removes all preferences set between factory
instances for a given descriptor and product. | | List | getFactoryList(String descriptorName, String productName)
Get a list of factory objects registered under the descriptor
and the product (in no particular order). | | String | getLocalName(Object factoryInstance)
| | Object[][] | getPreferences(String descriptorName, String productName)
Gets an iterator over all preferences set between factory
instances for a given descriptor and product. | | Object | invoke(Object factoryInstance, Object[] parameterValues)
Invoke the create method of the given factory instance
Parameters:
factoryInstance - an instance of this factory
Parameters:
parameterValues - the parameterValues to be passed in to thethe create method. | | void | removeFactory(String descriptorName, String productName, Object factoryInstance)
| | void | setPreference(String descriptorName, String productName, Object preferredOp, Object otherOp)
Sets a preference between two factory instances for the given
operation and product. | | void | unsetPreference(String descriptorName, String productName, Object preferredOp, Object otherOp)
Unets a preference between two factory instances for the given
operation and product. |
| arePreferencesSupported | | final boolean arePreferencesSupported(Code) | | does the factory support preferences both among products
and among multiple instances of the factory within the
same product ?
|
| factoryClass | | final Class factoryClass(Code) | | The Class corresponding to the factory.
|
| factoryMethod | | final Method factoryMethod(Code) | | The name of the method in this factory used to
do a "create"
|
| mode | | final RegistryMode mode(Code) | | Cache the RegistryMode since it is bound to get used
many, many times.
|
| FactoryCache | | FactoryCache(String modeName)(Code) | | Constructor. Create a FactoryCache to hold factory objects
for a specific mode.
Parameters:
modeName - the registry mode name. |
| addFactory | | void addFactory(String descriptorName, String productName, Object factoryInstance)(Code) | | Add a factory instance to this factory. If the factory has
NO preferences add it to a table hashed by just the operation name.
Otherwise add it to two tables, one hashed by a unique filename
(modeName + count) and the other hashed by the factory interface
name.
Parameters:
descriptorName - operation that this factory instance implements
Parameters:
productName - product to which this factory instance belongs
Parameters:
factoryInstance - the factory instance |
| clearPreferences | | void clearPreferences(String descriptorName, String productName)(Code) | | Removes all preferences set between factory
instances for a given descriptor and product.
Parameters:
descriptorName - operation that this factory instance implements
Parameters:
productName - product to which this factory instance belongs |
| getFactoryList | | List getFactoryList(String descriptorName, String productName)(Code) | | Get a list of factory objects registered under the descriptor
and the product (in no particular order).
|
| getLocalName | | String getLocalName(Object factoryInstance)(Code) | | Get the local name of a factoryInstance
|
| getPreferences | | Object[][] getPreferences(String descriptorName, String productName)(Code) | | Gets an iterator over all preferences set between factory
instances for a given descriptor and product.
Parameters:
descriptorName - operation that this factory instance implements
Parameters:
productName - product to which this factory instance belongs |
| removeFactory | | void removeFactory(String descriptorName, String productName, Object factoryInstance)(Code) | | Remove a facory instance associated with the specified operation
Parameters:
descriptorName - operation that this factory instance implements
Parameters:
productName - product to which this factory instance belongs
Parameters:
factoryInstance - the factory instance |
| setPreference | | void setPreference(String descriptorName, String productName, Object preferredOp, Object otherOp)(Code) | | Sets a preference between two factory instances for the given
operation and product.
Parameters:
descriptorName - operation that this factory instance implements
Parameters:
productName - product to which this factory instance belongs
Parameters:
preferredOp - the preferred factory instance
Parameters:
otherOp - the not-so preferred/other factory instance |
| unsetPreference | | void unsetPreference(String descriptorName, String productName, Object preferredOp, Object otherOp)(Code) | | Unets a preference between two factory instances for the given
operation and product.
Parameters:
descriptorName - operation that this factory instance implements
Parameters:
productName - product to which this factory instance belongs
Parameters:
preferredOp - the preferred factory instance
Parameters:
otherOp - the not-so preferred/other factory instance |
