RegexValidator


class RegexValidator : Parcelable, Validator

Defines if a field is valid based on a regular expression (regex).

See SaveInfo.Builder.setValidator(Validator) for examples.

Summary

Inherited constants
Int CONTENTS_FILE_DESCRIPTOR

Descriptor bit used with describeContents(): indicates that the Parcelable object's flattened representation includes a file descriptor.

Int PARCELABLE_WRITE_RETURN_VALUE

Flag for use with writeToParcel: the object being written is a return value, that is the result of a function such as "Parcelable someFunction()", "void someFunction(out Parcelable)", or "void someFunction(inout Parcelable)". Some implementations may want to release resources at this point.
