Direct Known Subclasses:

NumberedTransform

public class NamedTransform

extends AbstractAssignment

implements Theable

This class provides an implementation for the tranform valued primitives. It sets the named pair register to the value given, and as a side effect all prefixes are zeroed.

Example

 \trafo=1.1 2.2 3.3 4.4 5.5 6.6

NamedTransform

public NamedTransform(java.lang.String name)

Creates a new object.

Parameters:

name - the name for debugging

assign

public void assign(Flags prefix,
                   Context context,
                   TokenSource source,
                   Typesetter typesetter)
            throws InterpreterException

Description copied from class: AbstractAssignment

The method assign is the core of the functionality of execute(). This method is preferable to execute() since the execute() method provided in this class takes care of \afterassignment and \globaldefs as well.

Specified by:

assign in class AbstractAssignment

Parameters:

prefix - the prefix controlling the execution

context - the interpreter context

source - the token source

typesetter - the typesetter

Throws:

InterpreterException - in case of an error

AbstractAssignment.assign( de.dante.extex.interpreter.Flags, de.dante.extex.interpreter.context.Context, de.dante.extex.interpreter.TokenSource, de.dante.extex.typesetter.Typesetter)

set

public void set(Context context,
                Transform value)
         throws InterpreterException

set the value

Parameters:

context - the interpreter context

value - the new value

Throws:

InterpreterException - if a error occured.

set

public void set(Context context,
                java.lang.String value)
         throws InterpreterException

Set the value

Parameters:

context - the interpreter context

value - the new value as String

Throws:

InterpreterException - if an error occured.

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

Theable.the( de.dante.extex.interpreter.context.Context, de.dante.extex.interpreter.TokenSource, Typesetter)

getKey

protected java.lang.String getKey(Context context,
                                  TokenSource source)
                           throws InterpreterException

Return the key (the name of the primitive) for the register.

Parameters:

context - the context

source - the source

Returns:

the key

Throws:

InterpreterException - if an error occured.
