### `isResolvable`
```typescript theme={null}
import { Tokenization } from 'cdktn'
Tokenization.isResolvable(obj: any)
```
Return whether the given object is an IResolvable object.
This is different from Token.isUnresolved() which will also check for
encoded Tokens, whereas this method will only do a type check on the given
object.
#### `obj`Required
* *Type:* any
***
### `resolve`
```typescript theme={null}
import { Tokenization } from 'cdktn'
Tokenization.resolve(obj: any, options: ResolveOptions)
```
Resolves an object by evaluating all tokens and removing any undefined or empty objects or arrays.
Values can only be primitives, arrays or tokens. Other objects (i.e. with methods) will be rejected.
#### `obj`Required
* *Type:* any
The object to resolve.
***
#### `options`Required
* *Type:* ResolveOptions
Prefix key path components for diagnostics.
***
### `reverse`
```typescript theme={null}
import { Tokenization } from 'cdktn'
Tokenization.reverse(x: any)
```
Reverse any value into Resolvables, if possible.
#### `x`Required
* *Type:* any
***
### `reverseList`
```typescript theme={null}
import { Tokenization } from 'cdktn'
Tokenization.reverseList(l: string[])
```
Un-encode a Tokenized value from a list.
#### `l`Required
* *Type:* string\[]
***
### `reverseMap`
```typescript theme={null}
import { Tokenization } from 'cdktn'
Tokenization.reverseMap(m: {[ key: string ]: any})
```
Un-encode a Tokenized value from a map.
#### `m`Required
* *Type:* \{\[ key: string ]: any}
***
### `reverseNumber`
```typescript theme={null}
import { Tokenization } from 'cdktn'
Tokenization.reverseNumber(n: number)
```
Un-encode a Tokenized value from a number.
#### `n`Required
* *Type:* number
***
### `reverseNumberList`
```typescript theme={null}
import { Tokenization } from 'cdktn'
Tokenization.reverseNumberList(l: number[])
```
Un-encode a Tokenized value from a list.
#### `l`Required
* *Type:* number\[]
***
### `reverseString`
```typescript theme={null}
import { Tokenization } from 'cdktn'
Tokenization.reverseString(s: string)
```
Un-encode a string potentially containing encoded tokens.
#### `s`Required
* *Type:* string
***
### `stringifyNumber`
```typescript theme={null}
import { Tokenization } from 'cdktn'
Tokenization.stringifyNumber(x: number)
```
Stringify a number directly or lazily if it's a Token.
If it is an object (i.e., \{ Ref: 'SomeLogicalId' }), return it as-is.
#### `x`Required
* *Type:* number
***
