Field Detail

typeCache

public Type typeCache

The SemanticAnalysis pass will store the type of this expression here.

typeCacheFilled

public boolean typeCacheFilled

Indicates whether the typeCache variable contains usable information.

parenthesized

public boolean parenthesized

Indicates whether this expression was parenthesized in the source.

Method Detail

senseValueChild

public void senseValueChild()

Supports the SemanticAnalysis pass which needs to notify MethodInvocations that are the immediate value child of a SenseStatement that it's allowable to invoke an array or generator classifier. Only MethodInvocation will need to override this method which does nothing by default.

SemanticAnalysis

getVariableTypes

public HashSet<Argument> getVariableTypes()

Returns a set of Arguments storing the name and type of each variable that is a subexpression of this expression. This method cannot be run before SemanticAnalysis runs.

containsQuantifiedVariable

public boolean containsQuantifiedVariable()

Determines if there are any quantified variables in this expression. This method cannot be run before SemanticAnalysis runs.
