copy()
Make a copy of this SystemFunction.
|
void |
exportAttributes(ExpressionPresenter out)
Export any context attributes held within the SystemFunction object.
|
AtomicComparer |
getAtomicComparer(XPathContext context)
During evaluation, get the pre-allocated atomic comparer if available, or allocate a new one otherwise
|
AtomicComparer |
getPreAllocatedAtomicComparer()
Get the pre-allocated atomic comparer, if available
|
StringCollator |
getStringCollator()
Get the collation if known statically, as a StringCollator object
|
void |
importAttributes(java.util.Properties attributes)
Import any attributes found in the export file, that is, any attributes output using
the exportAttributes method
|
boolean |
isSubstringMatchingFunction()
Ask whether this function needs a collation that can handle substring matching
|
protected void |
preAllocateComparer(AtomicType type0,
AtomicType type1,
StaticContext env,
boolean NaNequalsNaN)
During static analysis, if types are known and the collation is known, pre-allocate a comparer
for comparing atomic values.
|
void |
setCollationName(java.lang.String collationName) |
void |
setRetainedStaticContext(RetainedStaticContext retainedStaticContext)
Set the static context in which the function operates, for use with functions whose result
depends on the static context
