longAt
Returns the numeric value as Long at pointer, or null if the path is absent, the value is not a numeric primitive, or the value has a fractional component.
Return
The long value at the specified path, or null.
Receiver
The KpaStruct to traverse.
Parameters
The KPointer identifying the value to retrieve.
Parses path via KPointer.from and returns the numeric value as Long at that path, or null if absent, not numeric, or has a fractional component.
Return
The long value at the specified path, or null.
Receiver
The KpaStruct to traverse.
Parameters
A pointer string (RFC 6901, fragment, or dot-notation, dispatched by prefix).
Throws
if path is not a valid pointer string.
Returns the numeric value as Long at pointer, or null if the path is absent, the value is not a numeric primitive, or the value has a fractional component.
Return
The long value at the specified path, or null.
Receiver
The KpaList to traverse. * @throws IllegalStateException if an intermediate segment lands on a KpaPrimitive.
Parameters
The KPointer identifying the value to retrieve.
Parses path via KPointer.from and returns the numeric value as Long at that path, or null if absent, not numeric, or has a fractional component.
Return
The long value at the specified path, or null.
Receiver
The KpaList to traverse.
Parameters
A pointer string (RFC 6901, fragment, or dot-notation, dispatched by prefix).
Throws
if path is not a valid pointer string. * @throws IllegalStateException if an intermediate segment lands on a KpaPrimitive.
