NoSymbol

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

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

Does this symbol come from a currently compiled source file?

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 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 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 memoty 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
