Method Details

execute

public final TruffleString execute(TruffleStringBuilder sb)

Materialize this string builder to a TruffleString.

Since:

22.1

execute

public abstract TruffleString execute(TruffleStringBuilder sb,
 boolean lazy)

Materialize this string builder to a TruffleString. If lazy is true, sb's internal storage will be re-used even if there are unused bytes. Since the resulting string will have a reference to sb's internal storage, and TruffleString currently does not resize/trim the substring's internal storage at any point, the lazy variant effectively creates a memory leak! The caller is responsible for deciding whether this is acceptable or not.

Since:

22.1

create

public static TruffleStringBuilder.ToStringNode create()

Create a new TruffleStringBuilder.ToStringNode.

Since:

22.1

getUncached

public static TruffleStringBuilder.ToStringNode getUncached()

Get the uncached version of TruffleStringBuilder.ToStringNode.

Since:

22.1
