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()

Returns the number of bytes that are required to serialize this 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 java.lang.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 java.lang.String toString()

Returns the string representation of this record.

Overrides:

toString in class java.lang.Object

toXml

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

Overrides:

toXml in class EscherRecord

Parameters:

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

Returns:

xml representation of this record

getNumShapes

public int getNumShapes()

The number of shapes in this drawing group.

setNumShapes

public void setNumShapes(int field_1_numShapes)

The number of shapes in this drawing group.

getLastMSOSPID

public int getLastMSOSPID()

The last shape id used in this drawing group.

setLastMSOSPID

public void setLastMSOSPID(int field_2_lastMSOSPID)

The last shape id used in this drawing group.

getDrawingGroupId

public short getDrawingGroupId()

Gets the drawing group id for this record. This is encoded in the instance part of the option record.

Returns:

a drawing group id.

incrementShapeCount

public void incrementShapeCount()
