CodeThing

Method Summary
`void`	`addStanza(Interp interp, Thing[] argv, int lineno)` The `addStanza` method adds a new command and its arguments.
`RealThing`	`deepcopy()` CodeThing's `deepcopy` method makes a copy of all the stanzas, which in turn copy all their objects.
`protected static Thing`	`doCodeSubst(Interp interp, Thing thing)` `doCodeSubst` takes a code Thing and runs it, returning the result.
`protected static Thing`	`doGroupSubst(Interp interp, Thing thing)` `doGroupSubst` runs substitutions on 'groups' of things, such as "foo $foo [foo]".
`protected static Thing`	`doSubstSubst(Interp interp, Thing thing)` `doSubstSubst` runs substitutions on things of the SubstThing type, which means $foo or &foo in Hecl.
`static CodeThing`	`get(Interp interp, Thing thing)` `get` returns a CodeThing object from any kind of Thing - or returns an error.
`java.lang.String`	`getStringRep()` The `getStringRep` method returns a String representation of the commands it represents.
`Thing`	`run(Interp interp)` The `run` method runs the CodeThing.
`java.lang.String`	`thingclass()`

Method Detail

thingclass

public java.lang.String thingclass()

Specified by:: thingclass in interface RealThing

get

public static CodeThing get(Interp interp,
                            Thing thing)
                     throws HeclException

get returns a CodeThing object from any kind of Thing - or returns an error.

Parameters:: interp - an Interp value; thing - a Thing value
Returns:: a CodeThing value
Throws:: HeclException - if an error occurs

deepcopy

public RealThing deepcopy()
                   throws HeclException

CodeThing's deepcopy method makes a copy of all the stanzas, which in turn copy all their objects.

Specified by:: deepcopy in interface RealThing

Returns:: a RealThing value
Throws:: HeclException - if an error occurs

doCodeSubst

protected static Thing doCodeSubst(Interp interp,
                                   Thing thing)
                            throws HeclException

doCodeSubst takes a code Thing and runs it, returning the result. This is used for substitution in situations like this: "foo [bar] baz", where the substitution needs to be run every time, but the block can't be broken up. doCodeSubst operates on the [bar] word in the above case.

Parameters:: interp - an Interp value; thing - a Thing value
Returns:: a Thing value
Throws:: HeclException - if an error occurs

doSubstSubst

protected static Thing doSubstSubst(Interp interp,
                                    Thing thing)
                             throws HeclException

doSubstSubst runs substitutions on things of the SubstThing type, which means $foo or &foo in Hecl.

Parameters:: interp - an Interp value; thing - a Thing value
Returns:: a Thing value
Throws:: HeclException - if an error occurs

doGroupSubst

protected static Thing doGroupSubst(Interp interp,
                                    Thing thing)
                             throws HeclException

doGroupSubst runs substitutions on 'groups' of things, such as "foo $foo [foo]". The group can't be broken up, so it needs to be substituted together by subst'ing the individual components.

Parameters:: interp - an Interp value; thing - a Thing value
Returns:: a Thing value
Throws:: HeclException - if an error occurs

addStanza

public void addStanza(Interp interp,
                      Thing[] argv,
                      int lineno)

The addStanza method adds a new command and its arguments.

Parameters:: interp - Interp value; argv - Thing[] value

run

public Thing run(Interp interp)
          throws HeclException

The run method runs the CodeThing.

Parameters:: interp - Interp value
Throws:: HeclException - if an error occurs

getStringRep

public java.lang.String getStringRep()

The getStringRep method returns a String representation of the commands it represents.

Specified by:: getStringRep in interface RealThing

Returns:: a String value.
