Fields

public int flags

type of allowed leaf; must be set, because the default value (0) means none

Public Constructors

public Leaf (int id, int bitsize, int flags, INodeHandler handler)

Create a wildcard leaf. Can be a terminal (eg, EVar, EImm) or non-terminal (eg, complex expression).

Parameters
id a value in [0,1000[
handler custom optional handler to do custom processing (custom checks) on a matched node

public Leaf (int id, int bitsize, int flags)

Create a wildcard leaf. Can be a terminal (eg, EVar, EImm) or non-terminal (eg, complex expression).

Parameters
id a value in [0,1000[

public Leaf (long value, int bitsize, int id)

Create a fixed, pre-determined immediate constant leaf.

Parameters
value mandatory immediate value
bitsize optional, use 0 if unknown
id optional, use -1 if not needed, else an id in the [0,1000[ range; use if the leaf needs to be used in a subsequent substitution step

Public Methods
