Modifier and Type | Method and Description |
---|---|
static java.math.BigDecimal |
adjustToDecimal(double value,
int precision)
Convert a double to a BigDecimal.
|
void |
checkArguments(ExpressionVisitor visitor)
Method called during static type checking
|
java.lang.CharSequence |
evaluateAsString(XPathContext context)
Evaluate in a context where a string is wanted
|
Item |
evaluateItem(XPathContext c)
Evaluate in a general context
|
void |
fixup(DecimalSymbols dfs)
Fixup: this is a callback from the DecimalFormatManager used once the xsl:decimal-format
element is identified
|
Expression |
preEvaluate(ExpressionVisitor visitor)
preEvaluate: this method suppresses compile-time evaluation by doing nothing.
