Return a negative integer, zero, or a positive integer if this object is less than, equal to, or greater than the specified object:
this < that => <0
this == that => 0
this > that => >0
This method may also be accessed via the <
<=
<=>
>=
and >
shortcut operators. If not overridden the default
implementation compares the toStr
representations. Also see docLang.
Examples:
3.compare(8) => -1
8.compare(3) => 1
8.compare(8) => 0
3 <=> 8 => -1 // shortcut for 3.compare(8)
Compare this object to the specified for equality. This
method may be accessed via the == and != shortcut operators.
If not overridden the default implementation compares for
reference equality using the === operator. If this method
is overridden, then hash() must also be overridden such that
any two objects which return true for equals() must return
the same value for hash(). This method must accept null
and
return false.
Throw a test failure exception. If msg is non-null, include it in the failure exception.
Optional
msg: stringReturn a unique hashcode for this object. If a class overrides hash() then it must ensure if equals() returns true for any two objects then they have same hash code.
Setup is called before running each test method.
Teardown is called after running every test method.
Return a temporary test directory which may used as a scratch directory. This directory is guaranteed to be created and empty the first time this method is called for a given test run. The test directory is "{Env.cur.tempDir}/test/".
Get an immutable representation of this instance or throw NotImmutableErr if this object cannot be represented as an immutable:
Return a string representation of this object.
Trap a dynamic call for handling. Dynamic calls are invoked with the -> shortcut operator:
a->x a.trap("x", null)
a->x() a.trap("x", null)
a->x = b a.trap("x", [b])
a->x(b) a.trap("x", [b])
a->x(b, c) a.trap("x", [b, c])
The default implementation provided by Obj attempts to use reflection. If name maps to a method, it is invoked with the specified arguments. If name maps to a field and args.size is zero, get the field. If name maps to a field and args.size is one, set the field and return args[0]. Otherwise throw UnknownSlotErr.
Verify that cond is true, otherwise throw a test failure exception. If msg is non-null, include it in a failure exception. Identical to verifyTrue.
Optional
msg: stringVerify that a == b, otherwise throw a test failure exception. If both a and b are nonnull, then this method also ensures that a.hash == b.hash, because any two objects which return true for equals() must also return the same hash code. If msg is non-null, include it in failure exception.
Verify that the function throws an Err of the exact same type as errType (compare using === operator). If the errType parameter is null, then this method tests only that an exception is thrown, not its type.
Example:
verifyErr(ParseErr#) { x := Int.fromStr("@#!") }
Verify that cond is false, otherwise throw a test failure exception. If msg is non-null, include it in a failure exception.
Optional
msg: stringVerify that a is not null, otherwise throw a test failure exception. If msg is non-null, include it in a failure exception.
Optional
msg: stringVerify that a is null, otherwise throw a test failure exception. If msg is non-null, include it in a failure exception.
Optional
msg: stringVerify that cond is true, otherwise throw a test failure exception. If msg is non-null, include it in a failure exception. Identical to verify.
Optional
msg: stringThis method called whenever an it-block is applied to an
object. The default implementation calls the function with this
,
and then returns this

print an empty line.
