Class TransformSpi
java.lang.Object
org.apache.xml.security.transforms.TransformSpi
- Direct Known Subclasses:
TransformBase64Decode,TransformC14N,TransformC14N11,TransformC14N11_WithComments,TransformC14NExclusive,TransformC14NExclusiveWithComments,TransformC14NWithComments,TransformEnvelopedSignature,TransformXPath,TransformXPath2Filter,TransformXPointer,TransformXSLT
Base class which all Transform algorithms extend. The common methods that
have to be overridden are the
enginePerformTransform(XMLSignatureInput, Transform) method.-

enginePerformTransform
protected XMLSignatureInput enginePerformTransform(XMLSignatureInput input, OutputStream os, Transform transformObject) throws IOException, CanonicalizationException, InvalidCanonicalizerException, TransformationException, ParserConfigurationException, SAXException The mega method which MUST be implemented by the Transformation Algorithm.- Parameters:
input-XMLSignatureInputas the input of transformationos- where to output this transformation.transformObject- the Transform object- Returns:
XMLSignatureInputas the result of transformation- Throws:
CanonicalizationExceptionIOExceptionInvalidCanonicalizerExceptionParserConfigurationExceptionSAXExceptionTransformationException
-
enginePerformTransform
protected XMLSignatureInput enginePerformTransform(XMLSignatureInput input, Transform transformObject) throws IOException, CanonicalizationException, InvalidCanonicalizerException, TransformationException, ParserConfigurationException, SAXException The mega method which MUST be implemented by the Transformation Algorithm. In order to be compatible with preexisting Transform implementations, by default this implementation invokes the deprecated, thread-unsafe methods. Subclasses should override this with a thread-safe implementation.- Parameters:
input-XMLSignatureInputas the input of transformationtransformObject- the Transform object- Returns:
XMLSignatureInputas the result of transformation- Throws:
CanonicalizationExceptionIOExceptionInvalidCanonicalizerExceptionParserConfigurationExceptionSAXExceptionTransformationException
-
enginePerformTransform
protected XMLSignatureInput enginePerformTransform(XMLSignatureInput input) throws IOException, CanonicalizationException, InvalidCanonicalizerException, TransformationException, ParserConfigurationException, SAXException The mega method which MUST be implemented by the Transformation Algorithm.- Parameters:
input-XMLSignatureInputas the input of transformation- Returns:
XMLSignatureInputas the result of transformation- Throws:
CanonicalizationExceptionIOExceptionInvalidCanonicalizerExceptionParserConfigurationExceptionSAXExceptionTransformationException
-
engineGetURI
Returns the URI representation ofTransformation algorithm- Returns:
- the URI representation of
Transformation algorithm
