Method Detail

copy

IScope<K,V> copy()

Shallow copy this scope

getActivationCtx

IActivationContext getActivationCtx()

Get the activation record context. This can be any object representing the activation record e.g., a function symbol, a rule set context, whatever delimits a call boundary.

Returns:

The activation context.

countSymbols

int countSymbols()

visit all symbols in this Scope,

Returns:

true if the visitor want to continue visitiong other symbol/scope, false otherwise.

put

V put(K key,
      V value)

Specified by:

put in interface Map<K,V extends ISymbol>

getCSR

int getCSR()

Returns:

the compile-time csr for this scope if it exists

setCSR

void setCSR(int csr)
