Method Detail

convertCount

public long convertCount(Context context,
                         TokenSource source,
                         Typesetter typesetter)
                  throws InterpreterException
Description copied from interface: CountConvertible
This method converts a register into a count. It might be necessary to read further tokens to determine which value to use. For instance an additional register number might be required. In this case the additional arguments Context and TokenSource can be used.

Specified by:
convertCount in interface CountConvertible
Parameters:
context - the interpreter context
source - the source for new tokens
typesetter - the typesetter to use for conversion
Returns:
the converted value
Throws:
InterpreterException - in case of an error
See Also:
CountConvertible.convertCount( de.dante.extex.interpreter.context.Context, de.dante.extex.interpreter.TokenSource, de.dante.extex.typesetter.Typesetter)

execute

public void execute(Flags prefix,
                    Context context,
                    TokenSource source,
                    Typesetter typesetter)
             throws InterpreterException
Description copied from interface: Code
This method takes the first token and executes it. The result is placed on the stack. This operation might have side effects. To execute a token it might be necessary to consume further tokens.

Specified by:
execute in interface Code
Overrides:
execute in class AbstractCode
Throws:
InterpreterException
See Also:
Code.execute( de.dante.extex.interpreter.Flags, de.dante.extex.interpreter.context.Context, de.dante.extex.interpreter.TokenSource, de.dante.extex.typesetter.Typesetter)

the

public Tokens the(Context context,
                  TokenSource source,
                  Typesetter typesetter)
           throws InterpreterException
Description copied from interface: Theable
This method is the getter for the description of the primitive.

Specified by:
the in interface Theable
Parameters:
context - the interpreter context
source - the source for further tokens to qualify the request
typesetter - the typesetter to use
Returns:
the description of the primitive as list of Tokens
Throws:
InterpreterException - in case of an error
