class Document(
val text: String,
)
// Trim both 'g' and 'e' characters from the beginning and end
collection.aggregate()
.set {
Document::text set of(Document::text).trim('g', 'e')
}.toList()
// Trim space, 'g', and 'e' characters from the beginning and end
collection.aggregate()
.set {
Document::text set of(Document::text).trim(' ', 'g', 'e')
}.toList()
External resources¶
Removes the specified characters from the beginning and end of a string.
The characters parameter is a single string that can contain multiple characters to be trimmed. Each character in the string will be removed from both the beginning and end of the input string.
Example¶
class Document(
val text: String,
)
// Trim both 'g' and 'e' characters from the beginning and end
collection.aggregate()
.set {
Document::text set of(Document::text).trim(chars = of("ge"))
}.toList()
// Trim space, 'g', and 'e' characters from the beginning and end
collection.aggregate()
.set {
Document::text set of(Document::text).trim(chars = of(" ge"))
}.toList()
