public class EscherSimpleProperty
extends EscherProperty

A simple property is of fixed length and as a property number in addition to a 32-bit value. Properties that can't be stored in only 32-bits are stored as EscherComplexProperty objects.

Constructor Detail

EscherSimpleProperty

public EscherSimpleProperty(short id,
                            int propertyValue)

The id is distinct from the actual property number. The id includes the property number the blip id flag and an indicator whether the property is complex or not.

Parameters:

id - the property id

propertyValue - the property value

EscherSimpleProperty

public EscherSimpleProperty(short propertyNumber,
                            boolean isComplex,
                            boolean isBlipId,
                            int propertyValue)

Constructs a new escher property. The three parameters are combined to form a property id.

Parameters:

propertyNumber - the property number

isComplex - true, if its a complex property

isBlipId - true, if its a blip

propertyValue - the property value

Method Detail

serializeSimplePart

public int serializeSimplePart(byte[] data,
                               int offset)

Serialize the simple part of the escher record.

Specified by:

serializeSimplePart in class EscherProperty

Parameters:

data - the buffer to write to

offset - the starting position

Returns:

the number of bytes serialized.

serializeComplexPart

public int serializeComplexPart(byte[] data,
                                int pos)

Escher properties consist of a simple fixed length part and a complex variable length part. The fixed length part is serialized first.

Specified by:

serializeComplexPart in class EscherProperty

Parameters:

data - the buffer to write to

pos - the starting position

Returns:

the length of the part

getPropertyValue

public int getPropertyValue()

Returns:

Return the 32 bit value of this property.

equals

public boolean equals(Object o)

Returns true if one escher property is equal to another.

Overrides:

equals in class Object

hashCode

public int hashCode()

Returns a hashcode so that this object can be stored in collections that require the use of such things.

Overrides:

hashCode in class Object

toString

public String toString()

Specified by:

toString in class EscherProperty

Returns:

the string representation of this property.

toXml

public String toXml(String tab)

Overrides:

toXml in class EscherProperty
