    Creates an empty property list with the specified defaults.
    
    Parameters:
    
    defaults - the defaults
- Method Detail
  - clearDefaults
```
public void clearDefaults()
```
    Clear the defaults from this Properties set. This sets the default field to null and thus breaks any link with the Properties set that was the default.
  - writeExternal
```
public void writeExternal(java.io.ObjectOutput out)
                   throws java.io.IOException
```
    Write the properties out. Step through the enumeration and write the strings out in UTF.
    
    Specified by:
    
    writeExternal in interface java.io.Externalizable
    
    Parameters:
    
    out - write bytes here
    
    Throws:
    
    java.io.IOException - thrown on error
  - readExternal
```
public void readExternal(java.io.ObjectInput in)
                  throws java.io.IOException
```
    Read the properties from a stream of stored objects.
    
    Specified by:
    
    readExternal in interface java.io.Externalizable
    
    Parameters:
    
    in - read this.
    
    Throws:
    
    java.io.IOException - thrown on error
  - getTypeFormatId
```
public int getTypeFormatId()
```
    Get the formatID which corresponds to this class.
    
    Specified by:
    
    getTypeFormatId in interface TypedFormat
