Field Detail

VTX

protected static final org.eolang.Vertices VTX

Vertices.

vertex

protected int vertex

Identity of it (the ID of the vertex).

Constructor Detail

PhDefault

public PhDefault()

Ctor.

PhDefault

public PhDefault(Phi sigma)

Ctor.

Parameters:

sigma - Sigma

Method Detail

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

φTerm

public String φTerm()

Description copied from interface: Term

To φ-calculus term, as text.

Specified by:

φTerm in interface Term

Returns:

The expression in φ-calculus

toString

public String toString()

Overrides:

toString in class Object

copy

public final Phi copy()

Description copied from interface: Phi

Make a copy, leaving it at the same parent.

Specified by:

copy in interface Phi

Returns:

A copy

move

public final void move(Phi rho)

Description copied from interface: Phi

Move it to a new parent.

Specified by:

move in interface Phi

Parameters:

rho - New \rho to attach to

attr

public final Attr attr(int pos)

Description copied from interface: Phi

Get attribute by position.

Specified by:

attr in interface Phi

Parameters:

pos - The position of the attribute

Returns:

The attr

attr

public final Attr attr(String name)

Description copied from interface: Phi

Get attribute.

Specified by:

attr in interface Phi

Parameters:

name - The name of the attribute

Returns:

The attr

add

protected final void add(String name,
                         Attr attr)

Add new attribute. This method can only be called from child classes, in their constructors, when the declare their attributes. This is why it's protected. Not the brightest design, I admit.

Parameters:

name - The name

attr - The attr

toStringWith

protected String toStringWith(String... lines)

Make a string with this additional list of lines.

Parameters:

lines - Lines to show in addition

Returns:

The string
