              org.millscript.millscript.expr.BindingMapExpr

public final class BindingMapExpr
extends BindingExpr<BindingMapAction>

This class represents a for loop map binding expression. A map binding expression binds successive key-value pairs from a map to given names.

Constructor Summary

BindingMapExpr(NameExpr k, NameExpr v, Expr<?> i)
Constructs a new map binding expression, with the supplied key and value name expressions and map expression.

Method Summary

BindingMapAction	compileIt() Compiles this expression into an action.
void	resolve(CompilerState state) Resolves any NameExpr in the tree so that they refer to the correct ident.

Constructor Detail

BindingMapExpr

public BindingMapExpr(NameExpr k,
                      NameExpr v,
                      Expr<?> i)

Constructs a new map binding expression, with the supplied key and value name expressions and map expression.

Parameters:

k - the name expression for the key to bind to

v - the name expression for the value to bind to

i - the expression to generate the map to bind from

Method Detail

compileIt

public BindingMapAction compileIt()

Description copied from class: Expr

Compiles this expression into an action.

Specified by:

compileIt in class Expr<BindingMapAction>

Returns:

the Action for this expression

See Also:

Expr.compileIt()

resolve

public void resolve(CompilerState state)

Description copied from class: Expr

Resolves any NameExpr in the tree so that they refer to the correct ident. e.g. This method is responsible for ensuring that references to a function argument in the body of a function actually refer to the correct value.

Specified by:

resolve in class Expr<BindingMapAction>

Parameters:

state - the compiler state we are resolving in
