@NotNull List<MetadataValue>	getMetadata(@NotNull String metadataKey) Returns a list of previously set metadata values from the implementing object's metadata store.
boolean	hasMetadata(@NotNull String metadataKey) Tests to see whether the implementing object contains the given metadata value in its metadata store.
void	removeMetadata(@NotNull String metadataKey, @NotNull Plugin owningPlugin) Removes the given metadata value from the implementing object's metadata store.
void	setMetadata(@NotNull String metadataKey, @NotNull MetadataValue newMetadataValue) Sets a metadata value in the implementing object's metadata store.

Method Detail

setMetadata

void setMetadata(@NotNull
                 @NotNull String metadataKey,
                 @NotNull
                 @NotNull MetadataValue newMetadataValue)

getMetadata

@NotNull
@NotNull List<MetadataValue> getMetadata(@NotNull
                                                  @NotNull String metadataKey)

Returns a list of previously set metadata values from the implementing object's metadata store.

Parameters:

metadataKey - the unique metadata key being sought.

Returns:

A list of values, one for each plugin that has set the requested value.

hasMetadata

boolean hasMetadata(@NotNull
                    @NotNull String metadataKey)

Tests to see whether the implementing object contains the given metadata value in its metadata store.

Parameters:

metadataKey - the unique metadata key being queried.

Returns:

the existence of the metadataKey within subject.

removeMetadata

void removeMetadata(@NotNull
                    @NotNull String metadataKey,
                    @NotNull
                    @NotNull Plugin owningPlugin)

Removes the given metadata value from the implementing object's metadata store.

Parameters:
