contains code to support higher-order functions.See: Description
Class | Description |
---|---|
AtomicConstructorFunction |
A function item representing a constructor function for an atomic type
|
CallableWithBoundFocus |
A Callable that wraps another Callable and a Dynamic Context, in effect acting as a closure that
executes the original callable with a saved context.
|
CoercedFunction |
A function item obtained by coercing a supplied function; this adds a wrapper to perform dynamic
type checking of the arguments in any call, and type checking of the result.
|
CurriedFunction |
A function obtained by currying another function, that is, the result of calling
fn:partial-apply
|
FilterFn |
This class implements the function fn:filter(), which is a standard function in XQuery 3.0
|
FoldLeftFn |
This class implements the function fn:fold-left(), which is a standard function in XPath 3.0
|
FoldRightFn |
This class implements the function fn:fold-right(), which is a standard function in XQuery 1.1
|
ForEachFn |
This class implements the function fn:for-each() (formerly fn:map), which is a standard function in XQuery 3.0
|
ForEachPairFn |
This class implements the function fn:for-each-pair() (formerly fn:map-pairs()), which is a standard function in XQuery 3.0
|
FunctionArity |
This class implements the function function-arity(), which is a standard function in XPath 3.0
|
FunctionLiteral |
A FunctionLiteral is a wrapper around a FunctionItem; it is an expression, whose value is the function
that it wraps.
|
FunctionLookup |
This class supports the function-lookup() function in XPath 3.0.
|
FunctionName |
This class implements the function function-name(), which is a standard function in XPath 3.0
|
FunctionSequenceCoercer |
An FunctionSequenceCoercer is an expression that performs function coercion on a sequence of function items:
it takes a sequence of supplied items as input, and wraps each one in a CoercedFunction value, which dynamically
converts the supplied arguments to the required type, and converts the result in the opposite direction, or
throws a type error if conversion is not possible.
|
FunctionSequenceCoercer.Coercer | |
LoadXQueryModule |
This class implements the function load-xquery-module(), which is a standard function in XPath 3.1
|
PartialApply |
This expression class implements the operation of currying (or performing partial application) of a function.
|
RandomNumberGenerator |
This class implements the function random-number-generator(), which is a standard function in XPath 3.1
|
Sort_3 |
This class implements the function fn:sort#2, which is a higher-order function in XPath 3.1
available only in Saxon-PE and above
|
SystemFunctionWithBoundContextItem |
A Callable that wraps another Callable and a Dynamic Context, in effect acting as a closure that
executes the original callable with a saved context.
|
TypeHierarchyPE |
TypeHierarchy for Saxon-PE
|
UserFunctionReference |
A UserFunctionReference is an expression in the form local:f#1 where local:f is a user-defined function.
|
UserFunctionReference.BoundUserFunction |
A BoundUserFunction represents a user-defined function seen as a component.
|
The package com.saxonica.hof
contains code to support higher-order functions.
Higher-order functions are supported in XQuery 1.1 using native language syntax, and they
are also available in other environments (including XSLT) using the Saxon extension functions
saxon:function()
and saxon:call()
.
