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

Returns:

the short name for this escher record

getNumShapes

public int getNumShapes()

The number of shapes in this drawing group.

Returns:

the number of shapes

setNumShapes

public void setNumShapes(int field_1_numShapes)

The number of shapes in this drawing group.

Parameters:

field_1_numShapes - the number of shapes

getLastMSOSPID

public int getLastMSOSPID()

The last shape id used in this drawing group.

Returns:

the last shape id

setLastMSOSPID

public void setLastMSOSPID(int field_2_lastMSOSPID)

The last shape id used in this drawing group.

Parameters:

field_2_lastMSOSPID - the last shape id

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()

Increments the number of shapes

getAttributeMap

protected java.lang.Object[][] getAttributeMap()

Description copied from class: EscherRecord

For the purpose of providing toString() and toXml() a subclass can either override those methods or provide a Object[][] array in the form { { "Attribute Name (Header)", value, "optional attribute", value }, ... } .

Null values won't be printed.

The attributes record, version, instance, options must not be returned.

Specified by:

getAttributeMap in class EscherRecord

Returns:

the attribute map
