List of effectiveBooleanValue() Examples

Examples of effectiveBooleanValue()

client.net.sf.saxon.ce.value.Value.effectiveBooleanValue()
Get the effective boolean value of the expression. This returns false if the value is the empty sequence, a zero-length string, a number equal to zero, or the boolean false. Otherwise it returns true. @exception XPathException if any dynamic error occurs evaluating theexpression @return the effective boolean value
net.sf.saxon.value.Value.effectiveBooleanValue()
Get the effective boolean value of the expression. This returns false if the value is the empty sequence, a zero-length string, a number equal to zero, or the boolean false. Otherwise it returns true. @exception XPathException if any dynamic error occurs evaluating theexpression @return the effective boolean value
org.exist.xquery.value.Sequence.effectiveBooleanValue()
Get the effective boolean value of this sequence. Will be false if the sequence is empty, true otherwise. @throws XPathException
org.pdf4j.saxon.value.Value.effectiveBooleanValue()
Get the effective boolean value of the expression. This returns false if the value is the empty sequence, a zero-length string, a number equal to zero, or the boolean false. Otherwise it returns true. @exception XPathException if any dynamic error occurs evaluating theexpression @return the effective boolean value
