Modifier and Type | Method and Description |
---|---|
boolean |
equals(java.lang.Object other)
equals() is used when deciding whether two assertions are equal, as part of the type
subsumption algorithm.
|

getComponentAsFunction()
Get the schema component in the form of a function item.
|
XPathExpression |
getCondition()
Get the XPath expression representing the assertion.
|
java.lang.String |
getConditionText()
Get the original text of the condition.
|
java.lang.String |
getMessage()
Get the user-defined error message associated with the assertion
|
XPathStaticContext |
getStaticContext()
Get the static context for the expression
|
XPathVariable |
getValueVariable()
Get the variable bound to the name $value
|
int |
hashCode()
Hashcode is used when deciding whether two assertions are equal, as part of the type
subsumption algorithm.
|

Set the dynamic XPath context to respond appropriately to requests for documents and collections
|
void |

including the current error listener, URIResolver, and document pool, current date/time, etc.
To take advantage of validation parameters (saxon:param) this must be a ValidationContext; but
