Constructor Details

Context

public Context()

Construct a new empty instance.

Context

public Context(Formattable... args)

Construct a new instance with the arguments as the bindings for the first positions of Format.BoundVariables.

Context

public Context(String name,
 Formattable value)

Construct a new instance with one binding of a named Format.BoundVariable.

Method Details

put

public void put(String name,
 Formattable value)

Add or overwrite a binding for a Format.FreeVariable.

eval

public Format.Context eval(Format.Context outer,
 boolean partial)

Evaluates all values bound in this Context (ONLY TO FreeVariable ??) against the outer context given as parameter. If partial==false, they must completely be resolvable or else an Exception is thrown. Only if partial==true, the bindings of the outer context are copied to the result. The positional bindings of the outer context are appened to this context. FIXME???????
