Method Detail

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 it's children.

Overrides:

fillFields in class EscherBlipRecord

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

public int serialize(int offset,
                     byte[] data,
                     EscherSerializationListener listener)

Description copied from class: EscherRecord

Serializes the record to an existing byte array.

Overrides:

serialize in class EscherBlipRecord

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.

getRecordSize

public int getRecordSize()

Description copied from class: EscherRecord

Subclasses should effeciently return the number of bytes required to serialize the record.

Overrides:

getRecordSize in class EscherBlipRecord

Returns:

number of bytes

getUID

public byte[] getUID()

Gets the first MD4, that specifies the unique identifier of the uncompressed blip data

Returns:

the first MD4

setUID

public void setUID(byte[] uid)

Sets the first MD4, that specifies the unique identifier of the uncompressed blip data

Parameters:

uid - the first MD4

getPrimaryUID

public byte[] getPrimaryUID()

Gets the second MD4, that specifies the unique identifier of the uncompressed blip data

Returns:

the second MD4

setPrimaryUID

public void setPrimaryUID(byte[] primaryUID)

Sets the second MD4, that specifies the unique identifier of the uncompressed blip data

Parameters:

primaryUID - the second MD4

getUncompressedSize

public int getUncompressedSize()

Gets the uncompressed size (in bytes)

Returns:

the uncompressed size

setUncompressedSize

public void setUncompressedSize(int uncompressedSize)

Sets the uncompressed size (in bytes)

Parameters:

uncompressedSize - the uncompressed size

getBounds

public java.awt.Rectangle getBounds()

Get the clipping region of the metafile

Returns:

the clipping region

setBounds

public void setBounds(java.awt.Rectangle bounds)

Sets the clipping region

Parameters:

Returns:

true, if the metafile is compressed

setCompressed

public void setCompressed(boolean compressed)

Sets the compression of the metafile

Parameters:
