HTTPRedirectDeflateDecoder

public HTTPRedirectDeflateDecoder()

Method Details

getBindingURI

@Nonnull
@NotEmpty
public String getBindingURI()

Gets the SAML binding URI supported by this decoder.

Specified by:

getBindingURI in interface SAMLMessageDecoder

Returns:

SAML binding URI supported by this decoder

getBindingDescriptor

@Nullable
public BindingDescriptor getBindingDescriptor()

Get an optional BindingDescriptor to inject into SAMLBindingContext created.

Returns:

binding descriptor

setBindingDescriptor

public void setBindingDescriptor(@Nullable
BindingDescriptor descriptor)

Set an optional BindingDescriptor to inject into SAMLBindingContext created.

Parameters:

descriptor - a binding descriptor

doDecode

protected void doDecode()
                 throws MessageDecodingException

Performs the decoding logic. By the time this is called, this decoder has already been initialized and checked to ensure that it has not been destroyed.

Specified by:

doDecode in class AbstractMessageDecoder

Throws:

MessageDecodingException - thrown if there is a problem decoding the message

decodeMessage

protected InputStream decodeMessage(String message)
                             throws MessageDecodingException

Base64 decodes the SAML message and then decompresses the message.

Parameters:

message - Base64 encoded, DEFALTE compressed, SAML message

Returns:

the SAML message

Throws:

MessageDecodingException - thrown if the message can not be decoded

populateBindingContext

protected void populateBindingContext(MessageContext messageContext)

Populate the context which carries information specific to this binding.

Parameters:

messageContext - the current message context
