Constructor Detail

EscherProperty

public EscherProperty(short id)

EscherProperty

public EscherProperty(short propertyNumber,
                      boolean isComplex,
                      boolean isBlipId)

Constructs a new escher property. The three parameters are combined to form a property id.

Method Detail

getId

public short getId()

getPropertyNumber

public short getPropertyNumber()

isComplex

public boolean isComplex()

isBlipId

public boolean isBlipId()

getName

public java.lang.String getName()

getPropertySize

public int getPropertySize()

Most properties are just 6 bytes in length. Override this if we're dealing with complex properties.

toXml

public java.lang.String toXml(java.lang.String tab)

serializeSimplePart

public abstract int serializeSimplePart(byte[] data,
                                        int pos)

Escher properties consist of a simple fixed length part and a complex variable length part. The fixed length part is serialized first.

serializeComplexPart

public abstract int serializeComplexPart(byte[] data,
                                         int pos)

Escher properties consist of a simple fixed length part and a complex variable length part. The fixed length part is serialized first.
