public interface IURMeta

Metadata about an IURRepresentation

Method Summary

int	getContextSensitivity() Return the depth of sensitivity on the calling context (super stack).
int	getCreationCost() Return an abitrary integer cost quantifier for regenerating this representation- see typical accessors for costs they assign.
java.lang.String	getMimeType() Return the MIME (Multipurpose Internet Mail Extensions) type of the resource this representation represents
long	getPessimisticExpiryTime() Return a positive integer number of millseconds from the 1970 datum at which point the representation will need to be checked to see if it is expired- if it is before that time it can be assumed the representation _is_ valid without need to call isExpired()
int	getUsageCost() Return an abitrary integer cost quantifier for using this representation- this value is only significant for streaming resources
boolean	isExpired() Return true if the resource is considered expired and an IURAccessor should source a new representation
boolean	isIntermediate() Return true if the representation is considered to be of transient use within part of a larger operation, inputs to calculations and final results would not be intermediate.

Method Detail

getMimeType

java.lang.String getMimeType()

Return the MIME (Multipurpose Internet Mail Extensions) type of the resource this representation represents

getPessimisticExpiryTime

long getPessimisticExpiryTime()

Return a positive integer number of millseconds from the 1970 datum at which point the representation will need to be checked to see if it is expired- if it is before that time it can be assumed the representation _is_ valid without need to call isExpired()

isExpired

boolean isExpired()

Return true if the resource is considered expired and an IURAccessor should source a new representation

getCreationCost

int getCreationCost()

Return an abitrary integer cost quantifier for regenerating this representation- see typical accessors for costs they assign. This value helps caches decide the worth of data. The value accumulates in highly derived resources

getUsageCost

int getUsageCost()

Return an abitrary integer cost quantifier for using this representation- this value is only significant for streaming resources

isIntermediate

boolean isIntermediate()

Return true if the representation is considered to be of transient use within part of a larger operation, inputs to calculations and final results would not be intermediate.

getContextSensitivity

int getContextSensitivity()

Return the depth of sensitivity on the calling context (super stack). 0 means no sensitivity
