Class QualifiedNameInterning

  • public final class QualifiedNameInterning
extends java.lang.Object
    Provides methods for enabling and disabling the interning of strings used in QualifiedName.

    String interning is disabled by default. It can be enabled by setting the system property xtext.qn.interning to true or by calling enable().

    Caution: Setting the system property at runtime does not have an effect. Use enable() to enable String interning at runtime.

    Since:
    2.26.0
