Class EscherTextboxRecord

java.lang.Object

loci.poi.ddf.EscherRecord

loci.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)

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()

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()

Returns the number of bytes that are required to serialize this 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()

The short name for this record

Specified by:

getRecordName in class EscherRecord

toString

public String toString()

Overrides:

toString in class Object
