      extended by org.apache.poi.ddf.EscherTextboxRecord
All Implemented Interfaces:
java.lang.Cloneable

public final class EscherTextboxRecord
extends EscherRecord
implements java.lang.Cloneable

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

Returns:
the extra data

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.

Parameters:
b - the buffer which contains the data
start - the start position in the buffer
length - the length of the block

setData

public void setData(byte[] b)
Sets the extra data (in the parent application's format) to be contained by the record. Used when the parent application changes the contents.

Parameters:
b - the data

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 EscherTextboxRecord clone()
Description copied from class: EscherRecord
Escher records may need to be clonable in the future.

Overrides:
clone in class EscherRecord
Returns:
the cloned object

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

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
