Initializes the Token with the specified information.
Creates a Reduction
from this token. Returns self if the
node is already a Reduction
.
Creates a Reduction
from this token, adding the supplied
node as the second element.
Creates a Reduction
from this token, adding the supplied
nodes as the second and third element, respectively.
Creates a Reduction
from this token, adding the supplied
nodes as the second, third, and fourth element, respectively.
Returns a copy of this Token.
Returns the specified element, or null.
Returns the meaning of this node. If the node isEmpty(), returns the type of Token.NULL.
Returns the root of the node. By convention, all nodes have
a Token as the first element (or root), which indicates the type
of the node. May return null if the node isEmpty()
.
Returns the text of the root node. Uses getRoot(true)
to get the root, so you will only receive null in return if the
root token returns it.
Returns the starting column of the node. Returns -1 if not known.
Returns the starting line of the node. Returns -1 if not known.
Returns the text of the token. Equivalent to
getRootText()
when called directly.
Returns the actual type of the node. If the node isEmpty(), returns the type of Token.NULL.
Creates a token that represents a decimal number.
Creates a token that represents an identifier.
Creates a token that represents an integer.
Creates a token that represents a keyword. Returns null if the specified text isn't a keyword.
Creates a token with the specified meaning.
Creates a token that represents a double-quoted string.
Creates a token that represents a symbol, using a library for the text.
Creates a token that represents a symbol, using a library for the type.
Sets the meaning for this node (and it's root Token). Not valid if the node isEmpty(). Returns this token, for convenience.
Not advisable, but if you need to adjust the token's text, this will do it.
Returns the number of elements in the node (including root).
