Instance Method Details

#composite? ⇒ Boolean

Is this TypeKind composed of many values?

Returns:

  • (Boolean) 


25
 
# File 'lib/graph_ql/type_kinds.rb', line 25

def composite?; @composite; end

#fields? ⇒ Boolean

Does this TypeKind have queryable fields?

Returns:

  • (Boolean)

# File 'lib/graph_ql/type_kinds.rb', line 18

def fields?;    @fields;    end

#input? ⇒ Boolean

Is this TypeKind a valid query input?

Returns:

  • (Boolean)

# File 'lib/graph_ql/type_kinds.rb', line 22

def input?;     @input;     end

#resolve(type, value) ⇒ Object
