Constructor Detail

ActorModelScope

public ActorModelScope(NamedObj modelObject)

Create a new ActorModelScope for the given Ptolemy NamedObj element.

Parameters:

modelObject - The Ptolemy NamedObj which defines the expression parser model scope.

Method Detail

get

public Token get(java.lang.String name)
          throws IllegalActionException

Look up and return the value with the specified name in the scope. Return null if the name is not defined in this scope.

Parameters:

name - The name of the variable to be looked up.

Returns:

The token associated with the given name in the scope.

Throws:

IllegalActionException - If a value in the scope exists with the given name, but cannot be evaluated.

getType

public Type getType(java.lang.String name)
             throws IllegalActionException

Look up and return the type of the value with the specified name in the scope. Return null if the name is not defined in this scope.

Parameters:

name - The name of the variable to be looked up.

Returns:

The token associated with the given name in the scope.

Throws:

IllegalActionException - If a value in the scope exists with the given name, but cannot be evaluated.

getTypeTerm

public InequalityTerm getTypeTerm(java.lang.String name)
                           throws IllegalActionException

Look up and return the type term for the specified name in the scope. Return null if the name is not defined in this scope, or is a constant type.

Parameters:

name - The name of the variable to be looked up.

Returns:

The InequalityTerm associated with the given name in the scope.

Throws:

IllegalActionException - If a value in the scope exists with the given name, but cannot be evaluated.

identifierSet

public java.util.Set<java.lang.String> identifierSet()
                                              throws IllegalActionException

Return a list of names corresponding to the identifiers defined by this scope. If an identifier is returned in this list, then get() and getType() will return a value for the identifier. Note that generally speaking, this list is extremely expensive to compute, and users should avoid calling it. It is primarily used for debugging purposes.

Returns:

A list of names corresponding to the identifiers defined by this scope.

Throws:

IllegalActionException - If constructing the list causes it.
