Summary

Public functions
`java-static Unit`	`@Pure @InlineMe(replacement = "Preconditions.checkArgument(expression)", imports = "com.google.common.base.Preconditions") checkArgument(expression: Boolean)` This function is deprecated. Use checkArgument instead.
`java-static Unit`	`@Pure @InlineMe(replacement = "Preconditions.checkArgument(expression, errorMessage)", imports = "com.google.common.base.Preconditions") checkArgument(expression: Boolean, errorMessage: Any!)` This function is deprecated. Use checkArgument instead.
`java-static Int`	`@Pure checkIndex(index: Int, start: Int, limit: Int)` This function is deprecated. Use `checkElementIndex`, with an additional assertion to check a non-zero `start` value if needed.
`java-static Unit`	`@Pure @InlineMe(replacement = "Preconditions.checkState(Looper.myLooper() == Looper.getMainLooper(), \"Not in" + " application's main thread\")", imports = [""com.google.common.base.Preconditions"", ""android.os.Looper""]) checkMainThread()` This function is deprecated. Use checkState to assert `Looper.myLooper() == Looper.getMainLooper()` instead.
`java-static String!`	`@EnsuresNonNull(value = [""#1""]) @Pure checkNotEmpty(string: String?)` This function is deprecated. Use checkArgument with `isEmpty` instead.
`java-static String!`	`@EnsuresNonNull(value = [""#1""]) @Pure checkNotEmpty(string: String?, errorMessage: Any!)` This function is deprecated. Use checkArgument with `isEmpty` instead.
`java-static T!`	`@EnsuresNonNull(value = [""#1""]) @Pure @InlineMe(replacement = "Preconditions.checkNotNull(reference)", imports = "com.google.common.base.Preconditions") <T> checkNotNull(reference: T?)` This function is deprecated. Use checkNotNull instead.
`java-static T!`	`@EnsuresNonNull(value = [""#1""]) @Pure @InlineMe(replacement = "Preconditions.checkNotNull(reference, errorMessage)", imports = "com.google.common.base.Preconditions") <T> checkNotNull(reference: T?, errorMessage: Any!)` This function is deprecated. Use checkNotNull instead.
`java-static Unit`	`@Pure @InlineMe(replacement = "Preconditions.checkState(expression)", imports = "com.google.common.base.Preconditions") checkState(expression: Boolean)` This function is deprecated. Use checkState instead.
`java-static Unit`	`@Pure @InlineMe(replacement = "Preconditions.checkState(expression, errorMessage)", imports = "com.google.common.base.Preconditions") checkState(expression: Boolean, errorMessage: Any!)` This function is deprecated. Use checkState instead.
`java-static T!`	`@EnsuresNonNull(value = [""#1""]) @Pure @InlineMe(replacement = "Preconditions.checkNotNull(reference)", imports = "com.google.common.base.Preconditions") <T> checkStateNotNull(reference: T?)` This function is deprecated. Use checkNotNull instead.
`java-static T!`	`@EnsuresNonNull(value = [""#1""]) @Pure @InlineMe(replacement = "Preconditions.checkNotNull(reference, errorMessage)", imports = "com.google.common.base.Preconditions") <T> checkStateNotNull(reference: T?, errorMessage: Any!)` This function is deprecated. Use checkNotNull instead.
