NoSymbol

The compilation unit info (associated file, tasty versions, ...). Note that the returned CompilationUnitInfo might be from the top-level class containing this symbol instead of the directly enclosing class. Overridden in ClassSymbol

Overridden in NoSymbol

The source or class file from which this class or the class containing this symbol was generated, null if not applicable. Note that the returned classfile might be from the top-level class containing this symbol instead of the directly enclosing class.

The class file from which this class was generated, null if not applicable.

Copy a symbol, overriding selective fields. Note that coord and compilationUnitInfo will be set from the fields in owner, not the fields in sym.

The tree defining the symbol at pickler time, EmptyTree if none was retained

Set defining tree if this symbol retains its definition tree

The current denotation of this symbol

Remove symbol from scope of owning class

Remove symbol from scope of owning class after given phase. Create a fresh denotation for its owner class if the class does not already have one that starts being valid after phase.

This symbol entered into owner's scope (owner must be a class).

Enter this symbol in its class owner after given phase. Create a fresh denotation for its owner class if the class does not already have one that starts being valid after phase.

A fallback text representation, if the pattern matching in Printers does not have a case for this showable element

If this symbol satisfies predicate p this symbol, otherwise NoSymbol

Calculates a hash code value for the object.

The default hashing algorithm is platform dependent.

Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)) yet not be equal (o1.equals(o2) returns false). A degenerate implementation could always return 0. However, it is required that if two objects are equal (o1.equals(o2) returns true) that they have identical hash codes (o1.hashCode.equals(o2.hashCode)). Therefore, when overriding this method, be sure to verify that the behavior is consistent with the equals method.

Does this symbol come from a currently compiled source file?

Is this symbol valid in the current run and has an associated file that is not a binary file. e.g. This will return true for symbols defined by the user in a prior run of the REPL, that are still valid.

Is the symbol a pattern bound symbol?

Test whether symbol is private. This conservatively returns false if symbol does not yet have a denotation, or denotation is a class that is not yet read.

Special cased here, because it may be used on naked symbols in substituters

Is this the info of a type parameter? Will return false for symbols that are not type parameters.

Is symbol valid in current run?

The last known denotation of this symbol, without going through current

The current name of this symbol

This symbol, if it exists, otherwise the result of evaluating that

The original denotation of this symbol, without forcing anything

The info of the type parameter

The info of the type parameter as seen from a prefix type. For type parameter symbols, this is the memberInfo as seen from prefix. For type lambda parameters, it's the same as paramInfos as asSeenFrom has already been applied to the whole type lambda.

The parameter bounds, or the completer if the type parameter is an as-yet uncompleted symbol.

The name of the type parameter

A type that refers to the parameter

The variance of the type parameter

The variance of the type parameter, as a number -1, 0, +1. Bivariant is mapped to 1, i.e. it is treated like Covariant.

Does this symbol retain its definition tree? A good policy for this needs to balance costs and benefits, where costs are mainly memory leaks, in particular across runs.

The string representation of this showable element.

The string representation with each line after the first one indented by the given given margin (in spaces).

The summarized string representation of this showable element. Recursion depth is limited to some smallish value. Default is Config.summarizeDepth.

The symbol's signature if it is completed or a method, NotAMethod otherwise.

A symbol related to sym that is defined in source code.

The position of this symbol, or NoSpan if the symbol was not loaded from source or from TASTY. This is always a zero-extent position.

This positioned item, widened to SrcPos. Used to make clear we only need the position, typically for error reporting.

A trap to avoid calling x.symbol on something that is already a symbol. This would be expanded to toDenot(x).symbol which is guaraneteed to be the same as x. With the given setup, all such calls will give implicit-not found errors

The info of the TASTy from which this symbol was loaded, None if not applicable.

Returns a string representation of the object.

The default representation is platform dependent.

The text representation of this showable element. This normally dispatches to a pattern matching method in Printers.
