Overview

The isCharacter function checks the argument {obj} to determine if it is a Character object. If the object is a Character, the isCharacter function returns true. If the object is not a Character, false is returned.

Usage

The isCharacter function is used whenever it is necessary to determine if an object is a Character.

 

Syntax

Expression:

(isCharacter obj )


Arguments Name Type Description
Argument:objCharacter, String, Symbol, Vector, BitVector, ByteVector, IntVector, FltVector, ObjVector, Structure, Dictionary, Directory, Matrix, NumMatrix, Integer, Float, Number, Complex, Boolean An Analytic Object

Returns:

Returns true if the object is a Character, otherwise false is returned.
