org.zkoss.poi.ddf.EscherTextboxRecord

public class EscherTextboxRecord
extends EscherRecord

Holds data from the parent application. Most commonly used to store text in the format of the parent application, rather than in Escher format. We don't attempt to understand the contents, since they will be in the parent's format, not Escher format.

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.

getData

public byte[] getData()

Returns any extra data associated with this record. In practice excel does not seem to put anything here, but with PowerPoint this will contain the bytes that make up a TextHeaderAtom followed by a TextBytesAtom/TextCharsAtom

setData

public void setData(byte[] b,
                    int start,
                    int length)

Sets the extra data (in the parent application's format) to be contained by the record. Used when the parent application changes the contents.

setData

public void setData(byte[] b)

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

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()

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

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
