de.dante.extex.interpreter.type.AbstractCode
de.dante.extex.interpreter.primitives.conditional.AbstractIf
de.dante.extex.interpreter.primitives.conditional.Iftrue
- All Implemented Interfaces:
- Code, ExpandableCode, Localizable, java.io.Serializable
- 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
The formal description of this primitive is the following:
〈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,
TokenSource source,
Typesetter typesetter)
- 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 contextsource
- the source for new tokenstypesetter
- the typesetter
- Returns:
- the boolean value
