Class MemberDeclaration

A member declaration in a class or interface, that is, either a method declaration or a field declaration.

Examples:

class Rectangle extends Shape {
  width;                            // field declaration
  height;                           // field declaration

  constructor(height, width) {      // constructor declaration, which is also a method declaration
    this.height = height;
    this.width = width;
  }

  area() {                          // method declaration
    return this.width*this.height;
  }
}

interface EventEmitter<T> {
  addListener(listener: (x: T) => void): void;  // method declaration
}

The subtype MemberSignature contains TypeScript members that are abstract, ambient, or overload signatures.

The subtype MemberDefinition contains all members that are not signatures. In regular JavaScript, all members are definitions.

There are also subtypes for working with specific kinds of members, such as FieldDeclaration, FieldSignature, and FieldDefinition, and similarly named subtypes for methods, constructors, and getters and setters.

getDecorator	Gets the `i`th decorator applied to this member.
getFirstControlFlowNode	Gets the first control flow node belonging to this syntactic entity.
getInit	Gets the expression specifying the initial value of the member; for methods and constructors this is always a function, for fields it may not be defined.
getMemberIndex	Gets the index of this member within its enclosing type.
getName	Gets the name of this member.
getNameExpr	Gets the expression specifying the name of this member, or nothing if this is a call signature.
getStaticAsBool	Gets a boolean indicating if this member is static.
hasImpureNameExpr	Holds if the name of this member is computed by an impure expression.
hasPrivateFieldName	Holds if the member has a private name, such as `#foo`, referring to a private field in the class.
hasPrivateKeyword	Holds if this is a TypeScript member annotated with the `private` keyword.
hasPublicKeyword	Holds if this is a TypeScript member explicitly annotated with the `public` keyword.
isAbstract	Holds if this member is abstract.
isComputed	Holds if the name of this member is computed.

isPrivate	Holds if this member is considered private.
isProtected	Holds if this is a TypeScript member annotated with the `protected` keyword.
isPublic	Holds if this member is public, either because it has no access modifier or because it is explicitly annotated as `public`.
isSignature	True if this is abstract, ambient, or an overload signature.
isStatic	Holds if this member is static.
toString	Gets a textual representation of this element.
