Class Metadata

java.lang.Object

wseemann.media.Metadata

public class Metadata
extends java.lang.Object

Class to hold the media's metadata. Metadata are used for human consumption and can be embedded in the media (e.g shoutcast) or available from an external source. The source can be local (e.g thumbnail stored in the DB) or remote. Metadata is like a Bundle. It is sparse and each key can occur at most once. The key is an integer and the value is the actual metadata. The caller is expected to know the type of the metadata and call the right get* method to fetch its value. //@hide //@deprecated Use MediaMetadata.

Method Detail

parse

public boolean parse(java.util.HashMap<java.lang.String,java.lang.String> metadata)

Check a parcel containing metadata is well formed. The header is checked as well as the individual records format. However, the data inside the record is not checked because we do lazy access (we check/unmarshall only data the user asks for.) Format of a metadata parcel:

                         1                   2                   3
      0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

      +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

      |                .... metadata records ....                     |
      |                                                               |

Parameters:

parcel - With the serialized data. Metadata keeps a reference on it to access it later on. The caller should not modify the parcel after this call (and not call recycle on it.)

Returns:

false if an error occurred.

has

public boolean has(java.lang.String metadataId)

Returns:

true if a value is present for the given key.

getAll

public java.util.HashMap<java.lang.String,java.lang.String> getAll()

Returns:

a map containing all of the available metadata.

getString

public java.lang.String getString(java.lang.String key)

getInt

public int getInt(java.lang.String key)

getBoolean

public boolean getBoolean(java.lang.String key)

Get the boolean value indicated by key

getLong

public long getLong(java.lang.String key)

getDouble

public double getDouble(java.lang.String key)

getByteArray

public byte[] getByteArray(java.lang.String key)

getDate

public java.util.Date getDate(java.lang.String key)
