secureValidation

protected final boolean secureValidation

Deprecated. Secure validation flag is now passed to methods.

Deprecated - used to carry state about whether resolution was being done in a secure fashion, but was not thread safe, so the resolution information is now passed as parameters to methods.

Method Detail

engineResolve

public XMLSignatureInput engineResolve(org.w3c.dom.Attr uri,
                                       java.lang.String BaseURI)
                                throws ResourceResolverException

Deprecated. New clients should override engineResolveURI(ResourceResolverContext)

This is the workhorse method used to resolve resources.

Parameters:

uri -

BaseURI -

Returns:

the resource wrapped around a XMLSignatureInput

Throws:

ResourceResolverException

engineResolveURI

public XMLSignatureInput engineResolveURI(ResourceResolverContext context)
                                   throws ResourceResolverException

This is the workhorse method used to resolve resources.

Parameters:

context - Context to use to resolve resources.

Returns:

the resource wrapped around a XMLSignatureInput

Throws:

ResourceResolverException

engineSetProperty

public void engineSetProperty(java.lang.String key,
                              java.lang.String value)

Method engineSetProperty

Parameters:

key -

value -

engineGetProperty

public java.lang.String engineGetProperty(java.lang.String key)

Method engineGetProperty

Parameters:

key -

Returns:

the value of the property

engineAddProperies

public void engineAddProperies(java.util.Map<java.lang.String,java.lang.String> newProperties)

Parameters:

newProperties -

engineIsThreadSafe

public boolean engineIsThreadSafe()

Tells if the implementation does can be reused by several threads safely. It normally means that the implementation does not have any member, or there is member change between engineCanResolve & engineResolve invocations. Or it maintains all member info in ThreadLocal methods.

engineCanResolve

public boolean engineCanResolve(org.w3c.dom.Attr uri,
                                java.lang.String BaseURI)

Deprecated. See engineCanResolveURI(ResourceResolverContext)

This method helps the ResourceResolver to decide whether a ResourceResolverSpi is able to perform the requested action.

Parameters:

uri -

BaseURI -

Returns:

true if the engine can resolve the uri

engineCanResolveURI

public boolean engineCanResolveURI(ResourceResolverContext context)

This method helps the ResourceResolver to decide whether a ResourceResolverSpi is able to perform the requested action.

New clients should override this method, and not override engineCanResolve(Attr, String)

Parameters:

context - Context in which to do resolution.

Returns:

true if the engine can resolve the uri

engineGetPropertyKeys

public java.lang.String[] engineGetPropertyKeys()

Method engineGetPropertyKeys

Returns:

the property keys

understandsProperty

public boolean understandsProperty(java.lang.String propertyToTest)

Method understandsProperty

Parameters:

propertyToTest -

Returns:

true if understands the property

fixURI

public static java.lang.String fixURI(java.lang.String str)

Fixes a platform dependent filename to standard URI form.

Parameters:

str - The string to fix.

Returns:

Returns the fixed URI string.
