All Implemented Interfaces:

GenericRecord

Direct Known Subclasses:

EscherArrayProperty

public class EscherComplexProperty
extends EscherProperty

A complex property differs from a simple property in that the data can not fit inside a 32 bit integer. See the specification for more detailed information regarding exactly what is stored here.

Constructor Detail

EscherComplexProperty

public EscherComplexProperty(short id,
                             int complexSize)

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

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.

complexSize - The byte size of this property.

EscherComplexProperty

public EscherComplexProperty(short propertyNumber,
                             boolean isBlipId,
                             int complexSize)

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

Parameters:

propertyNumber - The property number

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

complexSize - The byte size of this property.

EscherComplexProperty

public EscherComplexProperty(EscherPropertyTypes type,
                             boolean isBlipId,
                             int complexSize)

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

Parameters:

type - The property type

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

complexSize - The byte size of this property.

Method Detail
