Method Detail

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.

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.

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

getRecordId

public short getRecordId()

Description copied from class: EscherRecord

Return the current record id.

Overrides:

getRecordId in class EscherRecord

Returns:

The 16 bit record id.

getRecordName

public String getRecordName()

Description copied from class: EscherRecord

Subclasses should return the short name for this escher record.

Specified by:

getRecordName in class EscherRecord

toString

public String toString()

Overrides:

toString in class Object

Returns:

the string representation of this record.

toXml

public String toXml(String tab)

Overrides:

toXml in class EscherRecord

Parameters:

tab - - each children must be a right of his parent

Returns:

xml representation of this record
