Returns:

true if value is of type sequence

isValue

boolean isValue()

Returns:

true if value is of type value

isString

boolean isString()

Returns:

true if value is of type string

isDouble

Returns:

size of Any. For Value this is always 1.

asValue

Value asValue()

returns this Any as an Value object or throws an InvalidValueTypeException.

asMap

AnyMap asMap()

returns this Any as an AnyMap object or throws an InvalidValueTypeException.

asSeq

AnySeq asSeq()

returns this Any as an AnySeq object or throws an InvalidValueTypeException.
