Method Detail

addEscherProperty

public void addEscherProperty(EscherProperty prop)

Add a property to this record.

fillFields

public int fillFields(byte[] data,
                      int offset,
                      EscherRecordFactory recordFactory)

Description copied from class: EscherRecord

The contract of this method is to deserialize an escher record including it's children.

Specified by:

fillFields in class EscherRecord

Parameters:

data - The byte array containing the serialized escher records.

offset - The offset into the byte array.

recordFactory - A factory for creating new escher records.

Returns:

The number of bytes written.

getEscherProperties

public java.util.List<EscherProperty> getEscherProperties()

The list of properties stored by this record.

getEscherProperty

public EscherProperty getEscherProperty(int index)

The list of properties stored by this record.

getRecordSize

public int getRecordSize()

Description copied from class: EscherRecord

Subclasses should effeciently return the number of bytes required to serialize the record.

Specified by:

getRecordSize in class EscherRecord

Returns:

number of bytes

lookup

public <T extends EscherProperty> T lookup(int propId)

serialize

public int serialize(int offset,
                     byte[] data,
                     EscherSerializationListener listener)

Description copied from class: EscherRecord

Serializes the record to an existing byte array.

Specified by:

serialize in class EscherRecord

Parameters:

offset - the offset within the byte array

data - the data array to serialize to

listener - a listener for begin and end serialization events. This is useful because the serialization is hierarchical/recursive and sometimes you need to be able break into that.

Returns:

the number of bytes written.

sortProperties

public void sortProperties()

Records should be sorted by property number before being stored.

toString

public java.lang.String toString()

Retrieve the string representation of this record.

Overrides:

toString in class java.lang.Object
