public class Iftrue

extends AbstractIf

This class provides an implementation for the primitive \iftrue.

The Primitive \iftrue

The primitive does not take any further arguments. The conditional is always true. Thus only the then branch is expanded.

Syntax

    ⟨iftrue⟩
      → \iftrue ⟨true text⟩ \fi
      | \ifture ⟨true text⟩ \else ⟨false text⟩ \fi 

Examples

    \iftrue abc \fi

Iftrue

public Iftrue(java.lang.String name)

Creates a new object.

Parameters:

name - the name for debugging

conditional

protected boolean conditional(Context context,

Description copied from class: AbstractIf

This method computes the boolean value of the conditional. If the result is true then the then branch is expanded and the else branch is skipped. Otherwise the then branch is skipped and the else branch is expanded.

Specified by:

conditional in class AbstractIf

Parameters:

context - the interpreter context

source - the source for new tokens

typesetter - the typesetter

Returns:

the boolean value
