  - intValue
```
public int intValue()
```
    Accessor functions for scalar CosObjects. These are defined in the base class to avoid having to make an explicit cast after determining the subclass by either getType() or instanceof. The ones defined in the base class all throw RuntimeException. For each scalar subclass the appropriate method is overridden, so getting here represents a "can't happen" situation.

```
public double doubleValue()
```
    Returns double value if it's type of CosNumeric else throws exception.
  - numberValue
```
public java.lang.Number numberValue()
```
    Returns number value if it's type of CosNumeric else throws exception.
  - booleanValue
```
public boolean booleanValue()
```
    Returns boolean value if it's type of CosBoolean else throws exception.
  - nameValue

public ASName nameValue()
```
    Returns name value if it's type of CosName else throws exception.
  - stringValue
```
public ASString stringValue()
                     throws PDFSecurityException
```
    Returns string value if it's type of CosString else throws exception.
