Constructor Detail

DOMCanonicalizationMethod

public DOMCanonicalizationMethod(TransformService spi)
                          throws java.security.InvalidAlgorithmParameterException

Creates a DOMCanonicalizationMethod.

Parameters:

spi - TransformService

Throws:

java.security.InvalidAlgorithmParameterException

DOMCanonicalizationMethod

public DOMCanonicalizationMethod(org.w3c.dom.Element cmElem,
                                 XMLCryptoContext context,
                                 java.security.Provider provider)
                          throws MarshalException

Creates a DOMCanonicalizationMethod from an element. This ctor invokes the abstract unmarshalParams method to unmarshal any algorithm-specific input parameters.

Parameters:

cmElem - a CanonicalizationMethod element

Throws:

MarshalException

Method Detail

canonicalize

public Data canonicalize(Data data,
                         XMLCryptoContext xc)
                  throws TransformException

Canonicalizes the specified data using the underlying canonicalization algorithm. This is a convenience method that is equivalent to invoking the transform method.

Parameters:

data - the data to be canonicalized

xc - the XMLCryptoContext containing additional context (may be null if not applicable)

Returns:

the canonicalized data

Throws:

java.lang.NullPointerException - if data is null

TransformException - if an unexpected error occurs while canonicalizing the data

canonicalize

public Data canonicalize(Data data,
                         XMLCryptoContext xc,
                         java.io.OutputStream os)
                  throws TransformException

Throws:

TransformException

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class DOMTransform

hashCode

public int hashCode()

Overrides:

hashCode in class DOMTransform
