Method Detail

allowEmptyDescription

public static boolean allowEmptyDescription()

Indicates whether to allow schema elements to contain an empty string as the value for the DESC component. Although quoted strings are not allowed in schema elements as per RFC 4512 section 4.1, some directory servers allow it, and it may be necessary to support schema definitions used in conjunction with those servers.

The LDAP SDK does not allow empty schema element descriptions by default, but it may be updated to allow it using either the setAllowEmptyDescription(boolean) method or by setting the value of the com.unboundid.ldap.sdk.schema.AllowEmptyDescription system property to true before this class is loaded.

Returns:

true if the LDAP SDK should allow schema elements with empty descriptions, or false if not.

setAllowEmptyDescription

public static void setAllowEmptyDescription(boolean allowEmptyDescription)

Specifies whether to allow schema elements to contain an empty string as the value for the DESC component. If specified, this will override the value of the com.unboundid.ldap.sdk.schema.AllowEmptyDescription system property.

Parameters:

allowEmptyDescription - Indicates whether to allow schema elements to contain an empty string as the value for the DESC component.

getSchemaElementType

@NotNull
public abstract SchemaElementType getSchemaElementType()

Retrieves the type of schema element that this object represents.

Returns:

The type of schema element that this object represents.

hashCode

public abstract int hashCode()

Retrieves a hash code for this schema element.

Overrides:

hashCode in class java.lang.Object

Returns:

A hash code for this schema element.

equals

public abstract boolean equals(@Nullable
             java.lang.Object o)

Indicates whether the provided object is equal to this schema element.

Overrides:

equals in class java.lang.Object

Parameters:

o - The object for which to make the determination.

Returns:

true if the provided object may be considered equal to this schema element, or false if not.

extensionsEqual

protected static boolean extensionsEqual(@NotNull
                      java.util.Map<java.lang.String,java.lang.String[]> m1,
                      @NotNull
                      java.util.Map<java.lang.String,java.lang.String[]> m2)

Indicates whether the two extension maps are equivalent.

Parameters:

m1 - The first schema element to examine.

m2 - The second schema element to examine.

Returns:

true if the provided extension maps are equivalent, or false if not.

toString

@NotNull
public abstract java.lang.String toString()

Retrieves a string representation of this schema element, in the format described in RFC 4512.

Overrides:

toString in class java.lang.Object

Returns:

A string representation of this schema element, in the format described in RFC 4512.
