This method behaves as if: `ConstantPoolBuilder cpb = null; this.build(newClassName, cpb, clb -> clb.transform(model, transform));` ConstantPoolBuilder cpb = ... this.build(newClassName, cpb, clb -> clb.transform(model, transform)); where `cpb` is determined by `ConstantPoolSharingOption`.

equals	back to summary
public final boolean equals(Object o) Implements abstract java.lang.Record.equals. Doc from java.lang.Record.equals. Indicates whether some other object is "equal to" this one. In addition to the general contract of `Object.equals`, record classes must further obey the invariant that when a record instance is "copied" by passing the result of the record component accessor methods to the canonical constructor, as follows: R copy = new R(r.c1(), r.c2(), ..., r.cn()); then it must be the case that `r.equals(copy)`.

public final boolean equals(Object o)

Implements abstract java.lang.Record.equals.

In addition to the general contract of Object.equals, record classes must further obey the invariant that when a record instance is "copied" by passing the result of the record component accessor methods to the canonical constructor, as follows:

Obeys the general contract of `Object.hashCode`. For records, hashing behavior is constrained by the refined contract of `Record.equals`, so that any two records created from the same components must have the same hash code.

public final int hashCode()

Doc from java.lang.Record.hashCode.

toString	back to summary
public final String toString() Implements abstract java.lang.Record.toString. Doc from java.lang.Record.toString. Returns a string representation of the record. In accordance with the general contract of `Object#toString()`, the `toString` method returns a string that "textually represents" this record. The result should be a concise but informative representation that is easy for a person to read. In addition to this general contract, record classes must further participate in the invariant that any two records which are equal must produce equal strings. This invariant is necessarily relaxed in the rare case where corresponding equal component values might fail to produce equal strings for themselves.

public final String toString()
