de.dante.extex.interpreter.primitives.typesetter.spacing
Class Vfi

java.lang.Object
  de.dante.extex.interpreter.type.AbstractCode
      de.dante.extex.interpreter.primitives.typesetter.AbstractVerticalCode
          de.dante.extex.interpreter.primitives.typesetter.spacing.Vfi

All Implemented Interfaces:: Code, Localizable, java.io.Serializable, VerticalSkip

public class Vfi
extends AbstractVerticalCode
implements VerticalSkip

This class provides an implementation for the primitive \vfi.

The Primitive `\vfil`

The primitive \vfill inserts vertical glue into the current list. It switches to vertical mode if necessary. The amount of glue inserted has the natural height of 0pt and a stretchability of 1fi.

Syntax

The formal description of this primitive is the following:

    ⟨vfi⟩
        → \vfi

Examples

    \vfi

public Vfi(java.lang.String name)

Creates a new object.
Parameters:: name - the name for debugging

Method Detail

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)

getGlue

public FixedGlue getGlue(Context context,
                         TokenSource source,
                         Typesetter typesetter)

Description copied from interface: VerticalSkip

This method acquires a vertical glue.

Specified by:: getGlue in interface VerticalSkip

Parameters:: context - the interpreter context; source - the source for new tokens; typesetter - the typesetter
Returns:: the amount of vertical skip
See Also:: VerticalSkip.getGlue( de.dante.extex.interpreter.context.Context, de.dante.extex.interpreter.TokenSource, de.dante.extex.typesetter.Typesetter)
