Method Detail

getParent

public final @Nullable SymbolTable.Scope getParent()

getName

public final Identifier getName()

getNameOrNull

public final @Nullable Identifier getNameOrNull()

getQualifiedName

public final java.lang.String getQualifiedName()

buildFrameDescriptor

public com.oracle.truffle.api.frame.FrameDescriptor buildFrameDescriptor()

getTypeParameter

public @Nullable TypeParameter getTypeParameter(java.lang.String name)

getLexicalScope

public final SymbolTable.Scope getLexicalScope()

getConstDepth

public int getConstDepth()

Returns the lexical depth from the current scope to the top-most scope that is const. Depth is 0-indexed, and -1 means that the scope is not a const scope.

A const scope is a lexical scope on the right-hand side of a const property.

 const foo = new {
   bar {
     baz // <-- depth == 1
   }
 }
 

pushForGeneratorVariableContext

public int pushForGeneratorVariableContext(PklParser.ParameterContext ctx)

Adds the for generator variable to the frame descriptor.

Returns -1 if a for-generator variable already exists with this name.

popForGeneratorVariable

public void popForGeneratorVariable()

getForGeneratorVariables

public java.util.Deque<Identifier> getForGeneratorVariables()

skipLambdaScopes

public final SymbolTable.Scope skipLambdaScopes()

isModuleScope

public final boolean isModuleScope()

isClassScope

public final boolean isClassScope()

isClassMemberScope

public final boolean isClassMemberScope()

isLambdaScope

public final boolean isLambdaScope()

isCustomThisScope

public final boolean isCustomThisScope()

isLexicalScope

public final boolean isLexicalScope()

getConstLevel

public ConstLevel getConstLevel()
