In keeping with the design of "Collections.emptyList()", "Collections.emptySet()", etc. What about a DGSM on java.util.Arrays? Something like "Arrays.emptyArray()" which would accept generics or coercion like the Collections methods.
String[] empty = Arrays.emptyArray() def empty = Arrays.<String[]>emptyArray() ________________________________ From: Milles, Eric (TR Tech, Content & Ops) Sent: Wednesday, November 28, 2018 9:38:29 AM To: dev@groovy.apache.org Subject: Re: About adding `emptyArray` DGSM to arrays How would you return an empty multi-dimensional array? Your original proposal would cover that, correct? String[][].emptyArray() Under your new proposal, String.emptryArray() -> String[], is this it String[].emptyArray() -> String[][]? I do prefer "String.emptryArray()" at first glance. One-dimensional will be the most common use case by far. ________________________________ From: Daniel.Sun <sun...@apache.org> Sent: Wednesday, November 28, 2018 6:28 AM To: d...@groovy.incubator.apache.org Subject: Re: About adding `emptyArray` DGSM to arrays `String.emptyArray()` may be better Cheers, Daniel.Sun ----- Daniel Sun Apache Groovy committer Blog: https://urldefense.proofpoint.com/v2/url?u=http-3A__blog.sunlan.me&d=DwICAg&c=4ZIZThykDLcoWk-GVjSLmy8-1Cr1I4FWIvbLFebwKgY&r=tPJuIuL_GkTEazjQW7vvl7mNWVGXn3yJD5LGBHYYHww&m=7qbzGMIqJYoHbJpNbMib04Yqa0MBz3SmvB_HRFlzoVU&s=svUDTur2JydWqrY_bie1WA-6JNbPc5xortZfJ8mXwFw&e= Twitter: @daniel_sun -- Sent from: https://urldefense.proofpoint.com/v2/url?u=http-3A__groovy.329449.n5.nabble.com_Groovy-2DDev-2Df372993.html&d=DwICAg&c=4ZIZThykDLcoWk-GVjSLmy8-1Cr1I4FWIvbLFebwKgY&r=tPJuIuL_GkTEazjQW7vvl7mNWVGXn3yJD5LGBHYYHww&m=7qbzGMIqJYoHbJpNbMib04Yqa0MBz3SmvB_HRFlzoVU&s=U88DnA1FvITuWS-GDURFDVRsonTtWhcEymeU09TkljQ&e=
