Constructor Detail

PPN

public PPN()

Method Detail

compareTo

public int compareTo(PPN o)

Specified by:

compareTo in interface java.lang.Comparable<PPN>

normalizedValue

public java.lang.String normalizedValue()

Description copied from class: StandardNumber

Return normalized value of this standard number. In most cases, this is also the canonical form of the standard number. This is a representation without unneccessary characters, useful for computation purposes, like comparing for equivalence.

Specified by:

normalizedValue in class StandardNumber

Returns:

the normalized value

createChecksum

public PPN createChecksum(boolean createWithChecksum)

Description copied from class: StandardNumber

Indicate that a correct check sum should be computed.

Specified by:

createChecksum in class StandardNumber

Parameters:

createWithChecksum - if checksum is included

Returns:

this standard number

normalize

public PPN normalize()

Description copied from class: StandardNumber

Normalize the value by removing all unwanted characters or replacing characters with the ones required for verification.

Specified by:

normalize in class StandardNumber

Returns:

this standard number

isValid

public boolean isValid()

Description copied from class: StandardNumber

Check this number for validity.

Specified by:

isValid in class StandardNumber

Returns:

true if valid, false otherwise

verify

public PPN verify()

Description copied from class: StandardNumber

Verify the number.

Specified by:

verify in class StandardNumber

Returns:

this standard number if verification was successful

format

public java.lang.String format()

Description copied from class: StandardNumber

Return a formatted value of this standard number This is best for human-readable representation, but is not necessarily a format for computation.

Specified by:

format in class StandardNumber

Returns:

a formatted value

reset

public PPN reset()

Specified by:

reset in class StandardNumber

getTypedVariants

public java.util.Collection<java.lang.String> getTypedVariants()

Specified by:

getTypedVariants in class StandardNumber

equals

public boolean equals(java.lang.Object object)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Returns a clone if the implementation is cloneable.

Returns:

a clone if the implementation is cloneable.

Throws:

java.lang.CloneNotSupportedException - if this is called on an implementation that does not support `Cloneable`

getInstance

public static StandardNumber getInstance(java.lang.String type)
                                  throws NoSuchStandardNumberException

Throws:

NoSuchStandardNumberException

getInstance

public static StandardNumber getInstance(java.lang.Package thePackage,
                                         java.lang.ClassLoader classLoader,
                                         java.lang.String type)
                                  throws NoSuchStandardNumberException

Throws:

NoSuchStandardNumberException
