### Get all functions in the project

Source: https://docs.scitools.com/manuals/python/api/understand.Db.html

Example demonstrating how to retrieve a list of all functions within the project using the understand library.

```python
import understand

# Example usage (assuming 'db' is an initialized understand.Database object)
db = understand.Database()
functions = db.ents("function")
for func in functions:
    print(f"Function: {func.name()} (ID: {func.id()})")

```

### Simple Table Example

Source: https://docs.scitools.com/manuals/python/api/understand.ReportContext.html

Example of creating a simple table with two columns.

```python
report.table(["Column Name 1","Column Name 2"])

```

### Graph.options() Method

Source: https://docs.scitools.com/manuals/python/api/understand.Graph.html

Example of how to use the options() method to get the available options for a specific graph and target.

```python
options(_target_) → understand.Options
    
    Return options available for the given graph and target. 

Parameters:
    
**target** (_understand.Db_ _,__understand.Ent_ _, or_ _understand.Arch_) – database, entity, or architecture the graph applies to 

Return type:
    
understand.Options
```

--------------------------------

### Example of setting options using a string

Source: https://docs.scitools.com/manuals/python/api/understand.Options.html

Demonstrates the format for setting multiple options using a semicolon-separated string.

```text
Layout=Crossing; name=Fullname;Level=AllLevels
Comments=On;Show Entity Name=On
```

--------------------------------

### understand.open

Source: https://docs.scitools.com/manuals/python/api/understand.html

Open a database from the passed in filename.

```python
understand.open(_dbname_) 
    
    Open a database from the passed in filename. 

Parameters:
    
**dbname** (_str_) – the filename of the database 

Return type:
    
understand.Db 

Returns:
    
An opened database 

Raises:
    
**Understand.Error** – if unable to open the database
Possible causes for error are:
  * DBAlreadyOpen - only one database may be open at once
  * DBCorrupt - bad database file
  * DBOldVersion - database needs to be rebuilt
  * DBUnknownVersion - database needs to be rebuilt
  * DBUnableOpen - database is unreadable or does not exist
  * NoApiLicense - Understand license required
```

### Filtered Table Example

Source: https://docs.scitools.com/manuals/python/api/understand.ReportContext.html

Example of creating an interactive table with filtering and sorting options.

```python
[{
  "name" : "Column 1",
  "filtertype": "string"
 },{ 
  "name" : "Column 2",
  "filtertype": "numeric",
  "filteroperation": ">",
  "filtervalue": 10,
  "sort": "ascending"
 },{ 
  "name" : "Column 3",
  "filtertype" : ["Yes", "No"]
}]

```

### Open Database Example

Source: https://docs.scitools.com/manuals/python/api/understand.Db.html

Opens a SciTools Understand database and iterates through functions.

```Python
db = understand.open("test.und")

for func in db.ents("Function"):
    # print qualified name (ex: Namespace::ClassName::methodName)
    print(func.longname())
```
