Constructor Detail

Ctx

public Ctx(Map<String,Object> vars)

Ctx

public Ctx(Compiler.ICtx prev,
           Map<String,Object> vars)

Ctx

public Ctx(Compiler.ICtx prev,
           Map<String,Object> vars,
           boolean roCtx)

Make context based on parent context and map of value mappings.

If roCtx is true will be created context with empty mappings with parentcontext as described above.

Parameters:

prev - Parent context

vars - Variable mappings

roCtx - make extra child context.

Ctx

public Ctx()

Build empty context.

Ctx

public Ctx(Compiler.ICtx prev)

Create child context linking to previous context.

Ctx

public Ctx(Compiler.ICtx locals,
           Compiler.ICtx ctx)

Create child context linking to ctx as previous context and adding all local mapping from the locals context.
