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_pictureData = new byte[bytesAfterHeader]; System.arraycopy(data, pos, field_pictureData, 0, bytesAfterHeader); return bytesAfterHeader + 8;
public java.lang.String	getRecordName() The short name for this record return "Blip";
public int	getRecordSize() Returns the number of bytes that are required to serialize this record. return Number of bytes return field_pictureData.length + 4;
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() ); System.arraycopy( field_pictureData, 0, data, offset + 4, field_pictureData.length ); listener.afterRecordSerialize(offset + 4 + field_pictureData.length, getRecordId(), field_pictureData.length + 4, this); return field_pictureData.length + 4;
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 + " Extra Data:" + nl + extraData;
