Methods Summary
public int	fillFields(byte[] data, int offset, org.apache.poi.ddf.EscherRecordFactory recordFactory) This method deserializes the record from a byte array. param data The byte array containing the escher record information param offset The starting offset into data. param recordFactory May be null since this is not a container record. return The number of bytes read from the byte array. int bytesAfterHeader = readHeader( data, offset ); int pos = offset + HEADER_SIZE; field_1_UID = new byte[16]; System.arraycopy( data, pos, field_1_UID, 0, 16 ); pos += 16; field_2_marker = data[pos]; pos++; field_pictureData = new byte[bytesAfterHeader - 17]; System.arraycopy( data, pos, field_pictureData, 0, field_pictureData.length ); return bytesAfterHeader + HEADER_SIZE;
public byte	getMarker() return field_2_marker;
public byte[]	getPicturedata() return field_pictureData;
public int	getRecordSize() Returns the number of bytes that are required to serialize this record. return Number of bytes return 8 + 16 + 1 + field_pictureData.length;
public byte[]	getUID() return field_1_UID;
public int	serialize(int offset, byte[] data, org.apache.poi.ddf.EscherSerializationListener listener) Serializes the record to an existing byte array. param offset the offset within the byte array param data the data array to serialize to param 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. return the number of bytes written. listener.beforeRecordSerialize(offset, getRecordId(), this); LittleEndian.putShort( data, offset, getOptions() ); LittleEndian.putShort( data, offset + 2, getRecordId() ); LittleEndian.putInt( data, offset + 4, getRecordSize() - HEADER_SIZE ); int pos = offset + HEADER_SIZE; System.arraycopy( field_1_UID, 0, data, pos, 16 ); data[pos + 16] = field_2_marker; System.arraycopy( field_pictureData, 0, data, pos + 17, field_pictureData.length ); listener.afterRecordSerialize(offset + getRecordSize(), getRecordId(), getRecordSize(), this); return HEADER_SIZE + 16 + 1 + field_pictureData.length;
public void	setMarker(byte field_2_marker) this.field_2_marker = field_2_marker;
public void	setPictureData(byte[] pictureData) field_pictureData = pictureData;
public void	setUID(byte[] field_1_UID) this.field_1_UID = field_1_UID;
public java.lang.String	toString() String nl = System.getProperty( "line.separator" ); String extraData; ByteArrayOutputStream b = new ByteArrayOutputStream(); try { HexDump.dump( this.field_pictureData, 0, b, 0 ); extraData = b.toString(); } catch ( Exception e ) { extraData = e.toString(); } return getClass().getName() + ":" + nl + " RecordId: 0x" + HexDump.toHex( getRecordId() ) + nl + " Options: 0x" + HexDump.toHex( getOptions() ) + nl + " UID: 0x" + HexDump.toHex( field_1_UID ) + nl + " Marker: 0x" + HexDump.toHex( field_2_marker ) + nl + " Extra Data:" + nl + extraData;
