Class AsnSeq

Get the value as a math::BigInt.

Get the value as a sys::Bool

Get any of the binary values as a sys::Buf. The Buf will be a safe copy that can be modified. Throws AsnErr if the value is not a binary value.

Get this object as an AsnColl

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
Copy

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)
Copy

Apply rules for EXPLICIT and IMPLICIT tags to obtain the set of effective tags for encoding this object.

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.

Get an item value from the collection.

• If key is a sys::Str then get the named item.
• If key is an sys::Int, then get the item at that zero-based index.

Return 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.

Get the value as an sys::Int. If the value is a math::BigInt you may lose both precision and sign. Use bigInt to get the value explicitly as a math::BigInt.

Is this object's universal tag a Boolean

Is the collection empty

Return if this Obj is immutable and safe to share between threads:

• an instance of a const class
• the result of toImmutable on List, Map, or Buf
• a Func object may or may not be immutable - see sys::Func.
• other instances are assumed mutable and return false

Is this object's universal tag an Integer

Is this an ASN.1 Null value

Is this object's universal tag an Octet String

Is this object's universal tag an Object Identifier

Is this a primitive type?

Is this a SEQUENCE

Is this a SET

Get this object as an AsnOid

Push a tag to the front of the tag chain for this value. Returns a new instance of this object with the current value.

AsnObj.int(123).tag(AsnTag.implicit(TagClass.context, 0))
  => [0] IMPLICIT [UNIVERSAL 2]
AsnObj.int(123).tag(AsnTag.explicit(TagClass.app, 1))
  => [APPLICATION 1] EXPLICIT [UNIVERSAL 2]
Copy

Get this object as an AsnSeq

Get the number of items in the collection

Get the value as a sys::Str

Get the single effective tag for this object. Throws an error if there are multiple effective tags

The tags for this object.

Get an immutable representation of this instance or throw NotImmutableErr if this object cannot be represented as an immutable:

• if type is const, return this
• if already an immutable List, Map, Buf, or Func return this
• if a List, then attempt to perform a deep clone by calling toImmutable on all items
• if a Map, then attempt to perform a deep clone by calling toImmutable on all values (keys are already immutable)
• some Funcs can be made immutable - see sys::Func
• if a Buf create immutable copy, see sys::Buf
• any other object throws NotImmutableErr

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])
Copy

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.

Get the value as a sys::DateTime timestamp

Get the Type instance which represents this object's class. Also seeType.of or Pod.of.

Get the univ tag for this object

The value for this object.

Get the raw AsnObj values in the collection

This method called whenever an it-block is applied to an object. The default implementation calls the function with this, and then returns this.

Get a collection builder

Write x.toStr to standard output followed by newline. If x is null then print "null". If no argument is provided then print an empty line.
