Method Detail

addEscherProperty

public void addEscherProperty(EscherProperty prop)

Add a property to this record.

Parameters:

prop - the escher property to add

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 its 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.

getEscherProperties

public java.util.List<EscherProperty> getEscherProperties()

The list of properties stored by this record.

Returns:

the list of properties

getEscherProperty

public EscherProperty getEscherProperty(int index)

The list of properties stored by this record.

Parameters:

index - the ordinal index of the property

Returns:

the escher property

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

lookup

public <T extends EscherProperty> T lookup(EscherPropertyTypes propType)

lookup

public <T extends EscherProperty> T lookup(int propId)

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.

sortProperties

public void sortProperties()

Records should be sorted by property number before being stored.

setEscherProperty

public void setEscherProperty(EscherProperty value)

Set an escher property. If a property with given propId already exists it is replaced.

Parameters:

value - the property to set.

removeEscherProperty

public void removeEscherProperty(EscherPropertyTypes type)

getGenericProperties

public java.util.Map<java.lang.String,java.util.function.Supplier<?>> getGenericProperties()

Specified by:

getGenericProperties in interface GenericRecord

Overrides:

getGenericProperties in class EscherRecord
