fillFields
Description copied from class:EscherRecordThe contract of this method is to deserialize an escher record including it's children.- Specified by:
fillFieldsin classEscherRecord- 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
Description copied from class:EscherRecordSerializes the record to an existing byte array.- Specified by:
serializein classEscherRecord- Parameters:
offset- the offset within the byte arraydata- the data array to serialize tolistener- 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.
-
getRecordSize
public int getRecordSize()Description copied from class:EscherRecordSubclasses should effeciently return the number of bytes required to serialize the record.- Specified by:
getRecordSizein classEscherRecord- Returns:
- number of bytes
-
getRecordName
Description copied from class:EscherRecordSubclasses should return the short name for this escher record.- Specified by:
getRecordNamein classEscherRecord- Returns:
- the short name for this escher record
-
getPicturedata
public byte[] getPicturedata()Gets the picture data bytes- Returns:
- the picture data
-
setPictureData
public void setPictureData(byte[] pictureData) Sets the picture data bytes- Parameters:
pictureData- the picture data
-
setPictureData
public void setPictureData(byte[] pictureData, int offset, int length) Sets the picture data bytes- Parameters:
pictureData- the picture dataoffset- the offset into the picture datalength- the amount of bytes to be used
-
getAttributeMap
Description copied from class:EscherRecordFor 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:
