Constructor Detail

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.

EscherComplexProperty

public EscherComplexProperty(short propertyNumber,
                     boolean isBlipId,
                     byte[] complexData)

Create a complex property using the property number, a flag to indicate whether this is a blip reference and the complex property data.

Parameters:

propertyNumber - The property number

isBlipId - Whether this is a blip id. Should be false.

complexData - The value of this complex property.
