EscherComplexProperty

public EscherComplexProperty(short id,
                             byte[] complexData)

Create a complex property using the property id and a byte array containing the complex data value.

Parameters:

id - The id consists of the property number, a flag indicating whether this is a blip id and a flag indicating that this is a complex property.

complexData - The value of this property.
