Description copied from interface: Compiler

Compile the given tree and the trees in it. If this compiler cannot If this compiler encountered a tree that it cannot compile, this compiler will pass it to the given fallback compiler with the given compiler as the fallback compiler.
Unless this compiler want to change the default compiler, this compiler will invoke the given compiler with itself as the default compiler.

Specified by:

compile in interface Compiler

Parameters:

compiler - a compiler this compiler must use when dealing with other entities this compiler cannot compile.

compilation - the compilation the given tree was taken from.

tree - the tree to parse any instruction in it.

Returns:

the compiled instruction. Or null if this compiler failed to compile the given tree into an instruction.
