Package net.sf.saxon.ma.map
Class MapCreate
java.lang.Object
net.sf.saxon.functions.AbstractFunction
net.sf.saxon.functions.SystemFunction
net.sf.saxon.ma.map.MapCreate
- All Implemented Interfaces:
Callable,Function,GroundedValue,Item,Sequence
This is a variant of the map:new() or map:merge() function which differs in that duplicate
keys are considered an error. It is not available directly to users, but underpins the map
constructor expression in XPath and the xsl:map instruction in XSLT.
Moved to the Saxon namespace in 9.8 - see bug 2740 and test case function-available-1017

call
Description copied from interface:FunctionInvoke the function- Parameters:
context- the XPath dynamic evaluation contextarguments- the actual arguments to be supplied- Returns:
- the result of invoking the function
- Throws:
XPathException- if a dynamic error occurs within the function
-
getStreamerName
Description copied from class:SystemFunctionGet a name that identifies the class that can be used to evaluate this function in streaming mode, that is, supplying one item or event at a time as it is delivered by the parser. Special streaming support is generally available in Saxon-EE for all system functions that take a sequence as their argument.- Overrides:
getStreamerNamein classSystemFunction- Returns:
- a name that identifies a class that supports streamed evaluation of this system
function, or null if no such class is available. The mapping of names to classes is
defined in the Saxon-EE class
StreamerMap. In non-streaming Saxon editions (HE and PE) the method always returns null.
