Compile a pattern to bytecode:
In[1]:=
bc=
[_Integer]
 | CompilePatternToBytecode |
Out[1]=
PatternBytecode
 |
|
Create a virtual machine from the generated bytecode:
In[2]:=
vm=
[bc]
| CreatePatternMatcherVirtualMachine |
Out[2]=
PatternMatcherVirtualMachine
|
|
Execute the virtual machine against different expressions:
In[3]:=
 | PatternMatcherExecute |
Out[3]=
ResultTrue,CyclesExecuted6,Bindings
In[4]:=
| PatternMatcherExecute |
Out[4]=
ResultFalse,CyclesExecuted4,Bindings
Create a virtual machine for a pattern with variable bindings:
In[1]:=
bc=
[f[x_,x_]];vm=
[bc]
 | CompilePatternToBytecode |
| CreatePatternMatcherVirtualMachine |
Out[1]=
PatternMatcherVirtualMachine
|
|
Execute the virtual machine:
In[2]:=
| PatternMatcherExecute |
Out[2]=
ResultTrue,CyclesExecuted22,BindingsGlobal`x5
