Constructor Detail

DOMSignedInfo

public DOMSignedInfo(CanonicalizationMethod cm,
                     SignatureMethod sm,
                     List<? extends Reference> references)

Creates a DOMSignedInfo from the specified parameters. Use this constructor when the Id is not specified.

Parameters:

cm - the canonicalization method

sm - the signature method

references - the list of references. The list is copied.

Throws:

NullPointerException - if cm, sm, or references is null

IllegalArgumentException - if references is empty

ClassCastException - if any of the references are not of type Reference

DOMSignedInfo

public DOMSignedInfo(CanonicalizationMethod cm,
                     SignatureMethod sm,
                     List<? extends Reference> references,
                     String id)

Creates a DOMSignedInfo from the specified parameters.

Parameters:

cm - the canonicalization method

sm - the signature method

references - the list of references. The list is copied.

id - an optional identifer that will allow this SignedInfo to be referenced by other signatures and objects

Throws:

NullPointerException - if cm, sm, or references is null

IllegalArgumentException - if references is empty

ClassCastException - if any of the references are not of type Reference

DOMSignedInfo

public DOMSignedInfo(Element siElem,
                     XMLCryptoContext context,
                     Provider provider)
              throws MarshalException

Creates a DOMSignedInfo from an element.

Parameters:

siElem - a SignedInfo element

Throws:

MarshalException

Method Detail

getCanonicalizationMethod

public CanonicalizationMethod getCanonicalizationMethod()

Description copied from interface: SignedInfo

Returns the canonicalization method of this SignedInfo.

Specified by:

getCanonicalizationMethod in interface SignedInfo

Returns:

the canonicalization method

getSignatureMethod

public SignatureMethod getSignatureMethod()

Description copied from interface: SignedInfo

Returns the signature method of this SignedInfo.

Specified by:

getSignatureMethod in interface SignedInfo

Returns:

the signature method

getId

public String getId()

Description copied from interface: SignedInfo

Returns the optional Id attribute of this SignedInfo.

Specified by:

getId in interface SignedInfo

Returns:

the id (may be null if not specified)

getReferences

public List getReferences()

Description copied from interface: SignedInfo

Returns an unmodifiable list of one or more References.

Specified by:

getReferences in interface SignedInfo

marshal in class DOMStructure

Throws:

MarshalException

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:
