Constructor Detail

ExOleObjStg

public ExOleObjStg()

Constructs a new empty storage container.

ExOleObjStg

protected ExOleObjStg(byte[] source,
                      int start,
                      int len)

Constructs the link related atom record from its source data.

Parameters:

source - the source data as a byte array.

start - the start offset into the byte array.

len - the length of the slice in the byte array.

Method Detail

isCompressed

public boolean isCompressed()

getDataLength

public int getDataLength()

Gets the uncompressed length of the data.

Returns:

the uncompressed length of the data.

getData

public InputStream getData()

Opens an input stream which will decompress the data on the fly.

Returns:

the data input stream.

getRawData

public byte[] getRawData()

setData

public void setData(byte[] data)
             throws IOException

Sets the embedded data.

Parameters:

data - the embedded data.

Throws:

IOException

getRecordType

public long getRecordType()

Gets the record type.

Specified by:

getRecordType in class Record

Returns:

the record type.

getRecordInstance

public int getRecordInstance()

Gets the record instance from the header

Returns:

record instance

writeOut

public void writeOut(OutputStream out)
              throws IOException

Write the contents of the record back, so it can be written to disk.

Specified by:

writeOut in class Record

Parameters:

out - the output stream to write to.

Throws:

IOException - if an error occurs.

getPersistId

public int getPersistId()

Fetch our sheet ID, as found from a PersistPtrHolder. Should match the RefId of our matching SlidePersistAtom

Specified by:

getPersistId in interface PersistRecord

setPersistId

public void setPersistId(int id)

Set our sheet ID, as found from a PersistPtrHolder

Specified by:

setPersistId in interface PersistRecord

updateOtherRecordReferences

public void updateOtherRecordReferences(Map<Integer,Integer> oldToNewReferencesLookup)

Description copied from class: PositionDependentRecordAtom

Offer the record the list of records that have changed their location as part of the writeout. Allows records to update their internal pointers to other records locations

Specified by:

updateOtherRecordReferences in interface PositionDependentRecord

Specified by:

updateOtherRecordReferences in class PositionDependentRecordAtom

getGenericProperties

public Map<String,Supplier<?>> getGenericProperties()

Specified by:

getGenericProperties in interface GenericRecord
