Slot represents a member field or method on a Type.
Slots
- doc
-
Str doc()
Return the raw fandoc for this slot or null if not available.
- facet
-
Obj facet(Str name, Obj def := def)
Get a facet by name, or return the
def
is the facet is not defined. See the Facets Doc for details. - facets
-
Str:Obj facets()
Return all the facets defined for this slot or an empty map if no facets are defined. If looking up a facet by name, then use the facet method which will provide better performance. See the Facets Doc for details.
- find
-
static Slot find(Str qname, Bool checked := def)
Find a Slot by it's qualified name "pod::Type.slot". If the slot doesn't exist and checked is false then return null, otherwise throw UnknownSlotErr.
- findField
-
static Field findField(Str qname, Bool checked := def)
Convenience for
(Field)find(qname, checked)
- findFunc
-
static Func findFunc(Str qname, Bool checked := def)
Convenience for
findMethod(qname, checked).func
- findMethod
-
static Method findMethod(Str qname, Bool checked := def)
Convenience for
(Method)find(qname, checked)
- isAbstract
-
Bool isAbstract()
Return if slot is abstract (no implementation provided).
- isConst
-
Bool isConst()
Return if slot is constant and thread safe. A constant field is explicitly marked with the const modifier and guaranteed to always reference the same immutable object for the life of the VM. A const method is guaranteed to not capture any state from its thread, and is safe to execute on other threads. The compiler marks methods as const based on the following analysis:
- static methods are always automatically const
- instance methods are never const
- closures which don't capture any variables from their scope are automatically const
- partional apply methods which only capture const variables from their scope are automatically const
- isCtor
-
Bool isCtor()
Return if slot is constructor method.
- isField
-
Bool isField()
Return true if this is an instance of Field.
- isInternal
-
Bool isInternal()
Return if slot has internal protection scope.
- isMethod
-
Bool isMethod()
Return true if this is an instance of Method.
- isNative
-
Bool isNative()
Return if slot is native.
- isOverride
-
Bool isOverride()
Return if slot is an override (of parent's virtual method).
- isPrivate
-
Bool isPrivate()
Return if slot has private protection scope.
- isProtected
-
Bool isProtected()
Return if slot has protected protection scope.
- isPublic
-
Bool isPublic()
Return if slot has public protection scope.
- isStatic
-
Bool isStatic()
Return if slot is static (class based, rather than instance).
- isSynthetic
-
Bool isSynthetic()
Return if this slot was generated by the compiler.
- isVirtual
-
Bool isVirtual()
Return if slot is virtual (may be overridden in subclasses).
-
new make()
Internal constructor.
- name
-
Str name()
Simple name of the slot such as "size".
- parent
-
Type parent()
Parent type which defines this slot.
- qname
-
Str qname()
Qualified name such as "sys:Str.size".
- signature
-
virtual Str signature()
Return a string representation of the Fan code signature.
- toStr
-
override Str toStr()
Always return qname().
