    • Method Detail

      • union

        public abstract com.google.common.collect.ImmutableCollection<Color> union()

      • isPrimitive

        public final boolean isPrimitive()
        Whether this corresponds to a single JavaScript primitive like number or symbol or to a union of such primitives

        Note that the boxed versions of primitives (String, Number, etc.) are /not/ considered "primitive" by this method.

      • isClosureAssert

        public final boolean isClosureAssert()
        Whether this type is some Closure assertion function removable by Closure-specific optimizations.

      • isUnion

        public final boolean isUnion()

      • isInvalidating

        public final boolean isInvalidating()

      • propertiesKeepOriginalName

        public final boolean propertiesKeepOriginalName()

      • is

        public final boolean is​(NativeColorId color)
        Whether this is exactly the given native color (and not a union containing that color

      • isConstructor

        public final boolean isConstructor()
        Whether this is a constructor (a type that TypeScript or Closure allows calling with 'new'

        For unions, returns true if and only if all alternates in the union are constructors

      • getOwnProperties

        public com.google.common.collect.ImmutableSet<java.lang.String> getOwnProperties()

      • mayHaveProperty

        public boolean mayHaveProperty​(java.lang.String propertyName)
        Returns true if the color or any of its ancestors has the given property

        If this is a union, returns true if /any/ union alternate has the property.
