CacheSpan

Kotlin |Java

@UnstableApi
class CacheSpan : Comparable

Defines a span of data that may or may not be cached (as indicated by isCached).

Summary

Public constructors
`CacheSpan(key: String!, position: Long, length: Long)` Creates a hole CacheSpan which isn't cached, has no last touch timestamp and no file associated.
`CacheSpan( key: String!, position: Long, length: Long, lastTouchTimestamp: Long, file: File? )` Creates a CacheSpan.

Public functions
`Int`	`compareTo(another: CacheSpan!)`
`Boolean`	`isHoleSpan()` Returns whether this is a hole `CacheSpan`.
`Boolean`	`isOpenEnded()` Returns whether this is an open-ended `CacheSpan`.
`String!`	`toString()`

Public properties
`File?`	`file` The file corresponding to this `CacheSpan`, or null if `isCached` is false.
`Boolean`	`isCached` Whether the `CacheSpan` is cached.
`String!`	`key` The cache key that uniquely identifies the resource.
`Long`	`lastTouchTimestamp` The last touch timestamp, or `TIME_UNSET` if `isCached` is false.
`Long`	`length` The length of the `CacheSpan`, or `LENGTH_UNSET` if this is an open-ended hole.
`Long`	`position` The position of the `CacheSpan` in the resource.

CacheSpan(key: String!, position: Long, length: Long)

Creates a hole CacheSpan which isn't cached, has no last touch timestamp and no file associated.

Parameters
`key: String!`	The cache key that uniquely identifies the resource.
`position: Long`	The position of the `CacheSpan` in the resource.
`length: Long`	The length of the `CacheSpan`, or `LENGTH_UNSET` if this is an open-ended hole.

CacheSpan(
    key: String!,
    position: Long,
    length: Long,

    file: File?
)

Parameters
`key: String!`	The cache key that uniquely identifies the resource.
`position: Long`	The position of the `CacheSpan` in the resource.
`length: Long`	The length of the `CacheSpan`, or `LENGTH_UNSET` if this is an open-ended hole.
`lastTouchTimestamp: Long`	The last touch timestamp, or `TIME_UNSET` if `isCached` is false.
`file: File?`	The file corresponding to this `CacheSpan`, or null if it's a hole.
