MediaExtensionParser
public MediaExtensionParser()
getFeature
public Feature getFeature(Show show,
java.lang.String typeName,
java.lang.String name,
Lexer lexer)
throws java.io.IOException
- Get a feature of the given type.
The syntax of an extension feature is fixed at
"feature" "modifier" namespace:type_name name feature_name arguments ";"
This method gets a Lexer instance that is pointed to the beginning of
the arguments.
The implementation of this method is expected to return an instance of a feature
which loads on a standard JDK. It can be different from the feature class
that is going to be used with the xlet in the BD-J environment.
- Specified by:
getFeature
in interface ExtensionParser
- Parameters:
show
- The show being parsedtypeName
- The name of the feature's type. This will always
contain a ":".name
- The name of this instance of feature
a list of commands if needed.lexer
- The lexer to parse arguments for this feature.
The implementation of this method should parse up to ";"
which indicates the end of the feature declaration.
- Returns:
- A feature if one of the given type is known, null otherwise
- Throws:
java.io.IOException
- if there's an error.
getModifier
public Modifier getModifier(Show show,
java.lang.String typeName,
java.lang.String name,
Lexer lexer)
throws java.io.IOException
- Get a modifier feature of the given type. The type name will have a
colon in it. The sub-feature will automatically be set up for
you.
The syntax of an extension feature is fixed at
"feature" "modifier" namespace:type_name name feature_name arguments ";"
where feature_name is given iff the feature is a Modifier.
This method gets a Lexer instance that is pointed to the beginning of
the arguments.
The implementation of this method is expected to return an instance of a modifier
which loads on a standard JDK. It can be different from the modifier class
that is going to be used with the xlet in the BD-J environment.
- Specified by:
getModifier
in interface ExtensionParser
- Parameters:
show
- The show being parsedtypeName
- The name of the feature's type. This will always
contain a ":".name
- The name of this instance of feature
a list of commands if needed.lexer
- The lexer to parse arguments for this feature.
The implementation of this method should parse up to ";"
which indicates the end of the feature declaration.
- Returns:
- A feature if one of the given type is known, null otherwise
- Throws:
java.io.IOException
- if there's an error.
getCommand
public Command getCommand(Show show,
java.lang.String typeName,
Lexer lexer)
throws java.io.IOException
- Get a modifier command of the given type.
The implementation of this method is expected to return an instance of a command
which loads on a standard JDK. It can be different from the command class
that is going to be used with the xlet in the BD-J environment.
- Specified by:
getCommand
in interface ExtensionParser
- Parameters:
show
- The show being parsedtypeName
- The name of the commands's type. This will always
contain a ":".lexer
- The lexer to parse arguments for this feature.
The implementation of this method should parse up to ";"
which indicates the end of the feature declaration.
- Returns:
- A command if one of the given type is known, null otherwise
- Throws:
java.io.IOException
- if there's an error.
