Class SectionIDMap

java.lang.Object

java.util.AbstractMap<K,V>

java.util.HashMap

org.apache.poi.hpsf.wellknown.SectionIDMap

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.util.Map

public class SectionIDMap
extends java.util.HashMap

Maps section format IDs to PropertyIDMaps. It is initialized with two well-known section format IDs: those of the \005SummaryInformation stream and the \005DocumentSummaryInformation stream.

If you have a section format ID you can use it as a key to query this map. If you get a PropertyIDMap returned your section is well-known and you can query the PropertyIDMap for PID strings. If you get back null you are on your own.

This Map expects the byte arrays of section format IDs as keys. A key maps to a PropertyIDMap describing the property IDs in sections with the specified section format ID.

Method Detail

getInstance

public static SectionIDMap getInstance()

Returns the singleton instance of the default SectionIDMap.

Returns:

The instance value

getPIDString

public static java.lang.String getPIDString(byte[] sectionFormatID,
                                            long pid)

Returns the property ID string that is associated with a given property ID in a section format ID's namespace.

Parameters:

sectionFormatID - Each section format ID has its own name space of property ID strings and thus must be specified.

pid - The property ID

Returns:

The well-known property ID string associated with the property ID pid in the name space spanned by sectionFormatID . If the pid /sectionFormatID combination is not well-known, the string "[undefined]" is returned.

get

public PropertyIDMap get(byte[] sectionFormatID)

Returns the PropertyIDMap for a given section format ID.

Parameters:

sectionFormatID - the section format ID

Returns:

the property ID map

get

public java.lang.Object get(java.lang.Object sectionFormatID)

Deprecated. Use get(byte[]) instead!

Returns the PropertyIDMap for a given section format ID.

Specified by:

get in interface java.util.Map

Overrides:

get in class java.util.HashMap

Parameters:

sectionFormatID - A section format ID as a byte[] .

Returns:

the property ID map

put

public java.lang.Object put(byte[] sectionFormatID,
                            PropertyIDMap propertyIDMap)

Associates a section format ID with a PropertyIDMap.

Parameters:

sectionFormatID - the section format ID

propertyIDMap - the property ID map

Returns:

as defined by Map.put(K, V)

put

public java.lang.Object put(java.lang.Object key,
                            java.lang.Object value)

Deprecated. Use put(byte[], PropertyIDMap) instead!

Specified by:

put in interface java.util.Map

Overrides:

put in class java.util.HashMap

Parameters:

key - This parameter remains undocumented since the method is deprecated.

value - This parameter remains undocumented since the method is deprecated.

Returns:

The return value remains undocumented since the method is deprecated.
