Class OID

java.lang.Object

com.unboundid.util.OID

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<OID>

@NotMutable
@ThreadSafety(level=COMPLETELY_THREADSAFE)
public final class OID
extends java.lang.Object
implements java.io.Serializable, java.lang.Comparable<OID>

This class provides a data structure that may be used for representing object identifiers. Since some directory servers support using strings that aren't valid object identifiers where OIDs are required, this implementation supports arbitrary strings, but some methods may only be available for valid OIDs.

Constructor Detail

OID

public OID(java.lang.String oidString)

Creates a new OID object from the provided string representation.

Parameters:

oidString - The string to use to create this OID.

OID

public OID(int... components)

Creates a new OID object from the provided set of numeric components. At least one component must be provided for a valid OID.

Parameters:

components - The numeric components to include in the OID.

OID

public OID(java.util.List<java.lang.Integer> components)

Creates a new OID object from the provided set of numeric components. At least one component must be provided for a valid OID.

Parameters:

components - The numeric components to include in the OID.

Method Detail

parseComponents

public static java.util.List<java.lang.Integer> parseComponents(java.lang.String oidString)

Parses the provided string as a numeric OID and extracts the numeric components from it.

Parameters:

oidString - The string to parse as a numeric OID.

Returns:

The numeric components extracted from the provided string, or null if the provided string does not represent a valid numeric OID.

isValidNumericOID

public static boolean isValidNumericOID(java.lang.String s)

Indicates whether the provided string represents a valid numeric OID. Note this this method only ensures that the value is made up of a dotted list of numbers that does not start or end with a period and does not contain two consecutive periods. The isStrictlyValidNumericOID(String) method performs additional validation, including ensuring that the OID contains at least two components, that the value of the first component is not greater than two, and that the value of the second component is not greater than 39 if the value of the first component is zero or one.

Parameters:

s - The string for which to make the determination.

Returns:

true if the provided string represents a valid numeric OID, or false if not.

isValidNumericOID

public boolean isValidNumericOID()

Indicates whether the provided string represents a valid numeric OID. Note this this method only ensures that the value is made up of a dotted list of numbers that does not start or end with a period and does not contain two consecutive periods. The isStrictlyValidNumericOID() method performs additional validation, including ensuring that the OID contains at least two components, that the value of the first component is not greater than two, and that the value of the second component is not greater than 39 if the value of the first component is zero or one.

Returns:

true if this object represents a valid numeric OID, or false if not.

isStrictlyValidNumericOID

public static boolean isStrictlyValidNumericOID(java.lang.String s)

Indicates whether this object represents a strictly valid numeric OID. In addition to ensuring that the value is made up of a dotted list of numbers that does not start or end with a period or contain two consecutive periods, this method also ensures that the OID contains at least two components, that the value of the first component is not greater than two, and that the value of the second component is not greater than 39 if the value of the first component is zero or one.

Parameters:

s - The string for which to make the determination.

Returns:

true if this object represents a strictly valid numeric OID, or false if not.

isStrictlyValidNumericOID

public boolean isStrictlyValidNumericOID()

Indicates whether this object represents a strictly valid numeric OID. In addition to ensuring that the value is made up of a dotted list of numbers that does not start or end with a period or contain two consecutive periods, this method also ensures that the OID contains at least two components, that the value of the first component is not greater than two, and that the value of the second component is not greater than 39 if the value of the first component is zero or one.

Returns:

true if this object represents a strictly valid numeric OID, or false if not.

getComponents

public java.util.List<java.lang.Integer> getComponents()

Retrieves the numeric components that comprise this OID. This will only return a non-null value if isValidNumericOID(java.lang.String) returns true.

Returns:

The numeric components that comprise this OID, or null if this object does not represent a valid numeric OID.

hashCode

public int hashCode()

Retrieves a hash code for this OID.

Overrides:

hashCode in class java.lang.Object

Returns:

A hash code for this OID.

equals

public boolean equals(java.lang.Object o)

Indicates whether the provided object is equal to this OID.

Overrides:

equals in class java.lang.Object

Parameters:

o - The object for which to make the determination.

Returns:

true if the provided object is equal to this OID, or false if not.

compareTo

public int compareTo(OID oid)

Indicates the position of the provided object relative to this OID in a sorted list.

Specified by:

compareTo in interface java.lang.Comparable<OID>

Parameters:

oid - The OID to compare against this OID.

Returns:

A negative value if this OID should come before the provided OID in a sorted list, a positive value if this OID should come after the provided OID in a sorted list, or zero if the two OIDs represent equivalent values.

toString

public java.lang.String toString()

Retrieves a string representation of this OID.

Overrides:

toString in class java.lang.Object

Returns:

A string representation of this OID.
