Method Details

newPackage

public AggregateSymbol newPackage(EK9Parser.PackageBlockContext ctx)

Create a new EK9 package aggregate.

newProgram

public AggregateSymbol newProgram(EK9Parser.MethodDeclarationContext ctx)

Create a new aggregate that represents an EK9 program.

newApplication

public AggregateSymbol newApplication(EK9Parser.ApplicationDeclarationContext ctx)

Create a new aggregate that represents an EK9 application.

newDynamicVariableCapture

public CaptureScope newDynamicVariableCapture(ICanCaptureVariables scope,
 IScope enclosingBlockScope)

populateEnumeration

public void populateEnumeration(AggregateSymbol enumerationSymbol,
 List<org.antlr.v4.runtime.tree.TerminalNode> identifiers)

Populates the enumeration with each of the values supplied in the identifiers. This does check for duplicates and will raise errors if there are any.

newCall

public CallSymbol newCall(EK9Parser.CallContext ctx,
 IScope scope)

Symbol to model some type of call to a function, dynamic function, constructor, this, super etc.

newList

public CallSymbol newList(EK9Parser.ListContext ctx,
 IScope scope)

Create a new EK9 List (a generic type).

newDict

public CallSymbol newDict(EK9Parser.DictContext ctx,
 IScope scope)

Create a new EK9 Dictionary - like a Map.

newDictEntry

public CallSymbol newDictEntry(EK9Parser.InitValuePairContext ctx,
 IScope scope)

Create a new entry for the Dictionary, basically a tuple.

newInterpolatedStringPart

public ConstantSymbol newInterpolatedStringPart(EK9Parser.StringPartContext ctx)

Create a new constant that represents the fixed text part of an interpolated String.

newInterpolatedExpressionPart

public ExpressionSymbol newInterpolatedExpressionPart(EK9Parser.StringPartContext ctx)

Create a new expression that represents the expression part of and interpolated String.

newConstant

public ConstantSymbol newConstant(EK9Parser.ConstantDeclarationContext ctx)

Create a new constant as declared in the constants section.

newVariable

public VariableSymbol newVariable(EK9Parser.VariableDeclarationContext ctx)

Create and initialise a new variable symbol. Typically, a variable like name ← "Steve", so 'name' is the variable.

newVariable

public VariableSymbol newVariable(String name,
 IToken token,
 boolean nullAllowed,
 boolean injectionExpected)

Create new variable typically when looking to create simulated variable.

newVariable

public VariableSymbol newVariable(EK9Parser.IdentifierContext identifier,
 boolean nullAllowed,
 boolean injectionExpected)

newLiteral

public ConstantSymbol newLiteral(IToken start,
 String name)

Create a new aggregate that represents an EK9 literal value.
