Interface ProfileFileSupplier

All Superinterfaces:

Supplier<ProfileFile>

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface ProfileFileSupplier
extends Supplier<ProfileFile>

Encapsulates the logic for supplying either a single or multiple ProfileFile instances.

Each call to the Supplier.get() method will result in either a new or previously supplied profile based on the implementation's rules.

Method Summary

Modifier and Type	Method and Description
static ProfileFileSupplier	aggregate(ProfileFileSupplier... suppliers) Creates a ProfileFileSupplier by combining the ProfileFile objects from multiple ProfileFileSuppliers.
static ProfileFileSupplier	defaultSupplier() Creates a ProfileFileSupplier capable of producing multiple profile objects by aggregating the default credentials and configuration files as determined by ProfileFileLocation.credentialsFileLocation() abd ProfileFileLocation.configurationFileLocation().
static ProfileFileSupplier	fixedProfileFile(ProfileFile profileFile) Creates a ProfileFileSupplier that produces an existing profile.
static ProfileFileSupplier	reloadWhenModified(Path path, ProfileFile.Type type) Creates a ProfileFileSupplier capable of producing multiple profile objects from a file.

Method Detail

defaultSupplier

static ProfileFileSupplier defaultSupplier()

Creates a ProfileFileSupplier capable of producing multiple profile objects by aggregating the default credentials and configuration files as determined by ProfileFileLocation.credentialsFileLocation() abd ProfileFileLocation.configurationFileLocation(). This supplier will return a new ProfileFile instance only once either disk file has been modified. Multiple calls to the supplier while both disk files are unchanged will return the same object.

Returns:

Implementation of ProfileFileSupplier that is capable of supplying a new aggregate profile when either file has been modified.

reloadWhenModified

static ProfileFileSupplier reloadWhenModified(Path path,
                                              ProfileFile.Type type)

Creates a ProfileFileSupplier capable of producing multiple profile objects from a file. This supplier will return a new ProfileFile instance only once the disk file has been modified. Multiple calls to the supplier while the disk file is unchanged will return the same object.

Parameters:

path - Path to the file to read from.

type - The type of file. See ProfileFile.Type for possible values.

Returns:

Implementation of ProfileFileSupplier that is capable of supplying a new profile when the file has been modified.

fixedProfileFile

static ProfileFileSupplier fixedProfileFile(ProfileFile profileFile)

Creates a ProfileFileSupplier that produces an existing profile.

Parameters:

profileFile - Profile object to supply.

Returns:

Implementation of ProfileFileSupplier that is capable of supplying a single profile.

aggregate

static ProfileFileSupplier aggregate(ProfileFileSupplier... suppliers)

Creates a ProfileFileSupplier by combining the ProfileFile objects from multiple ProfileFileSuppliers. Objects are passed into ProfileFile.Aggregator.

Parameters:

suppliers - Array of ProfileFileSupplier objects. ProfileFile objects are passed to ProfileFile.Aggregator.addFile(ProfileFile) in the same argument order as the supplier that generated it.

Returns:

Implementation of ProfileFileSupplier aggregating results from the supplier objects.
