children. IMMUTABLE

returns attributes.
setter for attributes val
Creates a class to wrap the C struct described by signature
.
MyStruct = struct ['int i', 'char c']
Called when an instruction is encountered. EG: <?xsl sheet=‘foo’?> @p name the instruction name; in the example, “xsl” @p instruction the rest of the instruction. In the example, “sheet=‘foo’”
Returns an array of instance variable names for the receiver. Note that simply defining an accessor does not create the corresponding instance variable.
class Fred attr_accessor :a1 def initialize @iv = 3 end end Fred.new.instance_variables #=> [:@iv]
Returns self
.
If called on a subclass of String, converts the receiver to a String object.
Creates an accessor method to allow assignment to the attribute symbol.id2name
. String arguments are converted to symbols.
Makes a list of existing constants private.
IO.copy_stream
copies src to dst. src and dst is either a filename or an IO
.
This method returns the number of bytes copied.
If optional arguments are not given, the start position of the copy is the beginning of the filename or the current file offset of the IO
. The end position of the copy is the end of file.
If copy_length is given, No more than copy_length bytes are copied.
If src_offset is given, it specifies the start position of the copy.
When src_offset is specified and src is an IO
, IO.copy_stream
doesn’t move the current file offset.
Returns true for IPv4 private address (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16). It returns false otherwise.
Returns true for IPv4 multicast address (224.0.0.0/4). It returns false otherwise.
Returns true for IPv6 multicast address (ff00::/8). It returns false otherwise.
Builds a String in @encoding
. All chunks
will be transcoded to that encoding.
Returns true
if this is a lower triangular matrix.
Returns true
if this is an upper triangular matrix.
