  • Konstruktordetails

    • ExpressionType

      protected ExpressionType(Tree.Kind kind)
      Create a new expression type of the specified kind
      Parameter:
      kind - the type kind

  • Methodendetails

    • getKind

      public Tree.Kind getKind()
      Returns the kind of the compiler tree element
      Angegeben von:
      getKind in Schnittstelle Tree
      Gibt zurück:
      the tree kind of the expression type

    • accept

      public final <R, D> R accept(TreeVisitor<R,D> visitor, D data)
      Angegeben von:
      accept in Schnittstelle Tree

    • isAssignable

      public abstract int isAssignable(Transpiler transpiler, ExpressionType other)
      Checks whether a values of the specified type other is assignable to a variable of this type or not. If a value of that type is not assignable a negative value is returned. A zero or positive value is returned if it is assignable. A zero value indicates a perfect type match and greater values indicate a less perfect type match, e.g. unboxing of a primitive type is required or the a value of a sub class type should be assigned.
      Parameter:
      transpiler - the transpiler object used for utility methods
      other - the other type
      Gibt zurück:
      a postive value or zero if the type is assignable and a negative value if not.

    • isPrimitiveOrBoxedPrimitive

      public abstract boolean isPrimitiveOrBoxedPrimitive()
      Returns whether the type is a primitive type or a boxed primitive type.
      Gibt zurück:
      true if it is a primitive type and false otherwise

    • isString

      public boolean isString()
      Checks whether this type is the String type.
      Gibt zurück:
      true if it a string and false otherwise.

    • isNumberType

      public boolean isNumberType()
      Checks whether this type is a numeric or boxed numeric type. The method is an override in the subclasses ExpressionPrimitiveType and ExpressionClassType.
      Gibt zurück:
      true if it is a numeric type and false otherwise.

    • isIntegerType

      public boolean isIntegerType()
      Checks whether this type is an integer type. The method is an override in the subclasses ExpressionPrimitiveType and ExpressionClassType.
      Gibt zurück:
      true if it is an integer type and false otherwise.

    • getExpressionType

      public static ExpressionType getExpressionType(Transpiler transpiler, TypeMirror type) throws TranspilerException
      Determines the expression type for the specified abstract syntax tree (AST) node specified by the parameter 'type'.
      Parameter:
      transpiler - the transpiler used for determining the expression type
      type - the type mirror of the AST node
      Gibt zurück:
      the expression type
      Löst aus:
      TranspilerException - an exception if the expression type cannot be determined

    • getExpressionType

      public static ExpressionType getExpressionType(Transpiler transpiler, Tree type) throws TranspilerException
      Determines the expression type for the specified abstract syntax tree (AST) node specified by the parameter type.
      Parameter:
      transpiler - the transpiler used for determining the expression type
      type - the AST node
      Gibt zurück:
      the expression type
      Löst aus:
      TranspilerException - an exception if the expression type cannot be determined
