Command syntax

any.typeOf() → string

Description

Gets the type of a ReQL query’s return value.

The type will be returned as a string:

ARRAY
BOOL
DB
FUNCTION
GROUPED_DATA
GROUPED_STREAM
MAXVAL
MINVAL
NULL
NUMBER
OBJECT
PTYPE<BINARY>
PTYPE<GEOMETRY>
PTYPE<TIME>
SELECTION<ARRAY>
SELECTION<OBJECT>
SELECTION<STREAM>
STREAM
STRING
TABLE_SLICE
TABLE

Read the article on ReQL data types for a more detailed discussion. Note that some possible return values from typeOf are internal values, such as MAXVAL, and unlikely to be returned from queries in standard practice.

Example: Get the type of a string.

r.expr("foo").typeOf().run(conn, callback);
// Result passed to callback
"STRING"
