# IsObject

Determines whether a value is an object.

True conditions are:

* Box Class instances are "objects"
* All other classes that represent a Boxlang type are NOT "objects" (query, array, struct, XML, etc)
* These JDK classes which are used for "simple" BoxLang types are also not "objects" (String, Number, Boolean)
* Every other Java class is an "object"

## Method Signature

```
IsObject(value=[any])
```

### Arguments

| Argument | Type  | Required | Description       | Default |
| -------- | ----- | -------- | ----------------- | ------- |
| `value`  | `any` | `true`   | The value to test |         |

## Examples

### isObject Example

Returns true if the parameter is a BL object. The BL object here is a Java object.

[Run Example](https://try.boxlang.io/?code=eJwrSsxLyc9VsFVILkpNLEn1T8pKTS7RUFDKSixLVNKB0HrFqcmlRZkllXrBIEZqEFiPkoKmXnpqiWdecUliXnIqUE%2Bwh6NhQJCfO1DGmqscqCHVv7SkoBRoXGYxzOAiiH2aICUASxQo5w%3D%3D)

```java
random = createObject( "java", "java.security.SecureRandom" ).getInstance( "SHA1PRNG" );
writeOutput( isObject( random ) );

```

Result: true

### isObject Example for Other Data Types

Returns false if the parameter is any data type other than a BL object

[Run Example](https://try.boxlang.io/?code=eJxLrUjMLchJVbBVqFbg4lTKS8xNVVKwUlDyVEjMVUhUKC4pKk0uUeKqteYqL8osSfUvLSkoLdFQyCz2T8pKTQayUqEGaCpoWnMBALczGEY%3D)

```java
example = { 
	"name" : "I am a struct"
};
writeOutput( isObject( example ) );

```

Result: false

### Additional Examples

```java
writeDump( label="String value", var=isObject( "Susi" ) );
writeDump( label="isObject() with array function", var=isObject( arrayNew( 1 ) ) );
writeDump( label="CreateObject in Java", var=isObject( createObject( "java", "java.util.HashMap" ) ) );
writeDump( label="CreateObject in Java with init()", var=isObject( createObject( "java", "java.lang.StringBuffer" ).init() ) );

```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://boxlang.ortusbooks.com/boxlang-language/reference/built-in-functions/decision/isobject.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
