Method Detail

fillFields

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

This method deserializes the record from a byte array.

Specified by:

fillFields in class EscherRecord

Parameters:

data - The byte array containing the escher record information

offset - The starting offset into data.

recordFactory - May be null since this is not a container record.

Returns:

The number of bytes read from the byte array.

serialize

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

Writes this record and any contained records to the supplied 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.

getData

public byte[] getData()

getRecordSize

public int getRecordSize()

Returns the number of bytes that are required to serialize this record.

Specified by:

getRecordSize in class EscherRecord

Returns:

Number of bytes

getChildRecords

public List getChildRecords()

Overrides:

getChildRecords in class EscherRecord

Returns:

Returns the children of this record. By default this will be an empty list. EscherCotainerRecord is the only record that may contain children.

setChildRecords

public void setChildRecords(List childRecords)

Description copied from class: EscherRecord

Sets the child records for this record. By default this will throw an exception as only EscherContainerRecords may have children.

Overrides:

setChildRecords in class EscherRecord

Parameters:

childRecords - Not used in base implementation.

clone

public Object clone()

Description copied from class: EscherRecord

Escher records may need to be clonable in the future.

Overrides:

clone in class EscherRecord

getRecordName

public String getRecordName()

The short name for this record

Specified by:

getRecordName in class EscherRecord

toString

public String toString()

Overrides:

toString in class Object

addChildRecord

public void addChildRecord(EscherRecord childRecord)
