Class ProbeResult.Constant

java.lang.Object

org.apache.sis.storage.ProbeResult

org.apache.sis.storage.ProbeResult.Constant

All Implemented Interfaces:

Serializable

Enclosing class:

ProbeResult

private static final class ProbeResult.Constant
extends ProbeResult

Implementation of static constants defined in ProbeResult. We need a special implementation class in order to resolve deserialized instances to their unique instance.

Field Summary

Fields

Modifier and Type	Field	Description
private final String	name	The name of the public static field constant.
private static final long	serialVersionUID	For cross-version compatibility.

Fields inherited from class org.apache.sis.storage.ProbeResult

INSUFFICIENT_BYTES, SUPPORTED, UNDETERMINED, UNSUPPORTED_STORAGE

Constructor Summary

Constructors

Constructor	Description
Constant(boolean isSupported, String name)	Creates a new constant for a public static field of the given name.

Method Summary

Modifier and Type	Method	Description
boolean	equals(Object object)	Compares the name, which is okay since each name are unique.
int	hashCode()	Returns a hash code derived from the name, which is okay since each name are unique.
(package private) Object	readResolve()	Invoked on deserialization for fetching the unique instance, if possible.
String	toString()	Returns the constant name for debugging purpose.

• Constant Field Values

name

private final String name

The name of the public static field constant. Each name shall be unique.

Constructor Details

Constant

Constant(boolean isSupported,
 String name)

Creates a new constant for a public static field of the given name.

Method Details

readResolve

Object readResolve()
            throws ObjectStreamException

Invoked on deserialization for fetching the unique instance, if possible. If we fail to resolve (which may happen if the instance has been serialized by a more recent SIS version), returns the instance unchanged. It should be okay if all comparisons are performed by the equals method instead than the == operator.

Throws:

ObjectStreamException

equals

public boolean equals(Object object)

Compares the name, which is okay since each name are unique.

Overrides:

equals in class ProbeResult

Parameters:

object - the object to compare with this ProbeResult.

Returns:

true if the two objects are equal.

hashCode

public int hashCode()

Returns a hash code derived from the name, which is okay since each name are unique.

Overrides:

hashCode in class ProbeResult

toString

public String toString()

Returns the constant name for debugging purpose.

Overrides:

toString in class ProbeResult
