InputStreamTransferTo

SUGGESTION

Simplification

Suppression

Suppress false positives by adding the suppression annotation @SuppressWarnings("InputStreamTransferTo") to the enclosing element.

Disable this rule by adding -XepOpt:Refaster:NamePattern=^(?!InputStreamRules\$InputStreamTransferTo).* as compiler argument.

Samples

Shows the difference in example code before and after the Refaster rule is applied.

 long testInputStreamTransferTo() throws IOException {
-    return ByteStreams.copy(new ByteArrayInputStream(new byte[0]), new ByteArrayOutputStream());
+    return new ByteArrayInputStream(new byte[0]).transferTo(new ByteArrayOutputStream());
   }

InputStreamReadAllBytes

SUGGESTION

Simplification

Suppression

Suppress false positives by adding the suppression annotation @SuppressWarnings("InputStreamReadAllBytes") to the enclosing element.

Disable this rule by adding -XepOpt:Refaster:NamePattern=^(?!InputStreamRules\$InputStreamReadAllBytes).* as compiler argument.

Samples

Shows the difference in example code before and after the Refaster rule is applied.

 byte[] testInputStreamReadAllBytes() throws IOException {
-    return ByteStreams.toByteArray(new ByteArrayInputStream(new byte[0]));
+    return new ByteArrayInputStream(new byte[0]).readAllBytes();
   }

InputStreamReadNBytes

SUGGESTION

Simplification

Suppression

Suppress false positives by adding the suppression annotation @SuppressWarnings("InputStreamReadNBytes") to the enclosing element.

Disable this rule by adding -XepOpt:Refaster:NamePattern=^(?!InputStreamRules\$InputStreamReadNBytes).* as compiler argument.

Samples

Shows the difference in example code before and after the Refaster rule is applied.

 byte[] testInputStreamReadNBytes() throws IOException {
-    return ByteStreams.limit(new ByteArrayInputStream(new byte[0]), 0).readAllBytes();
+    return new ByteArrayInputStream(new byte[0]).readNBytes(0);
   }

InputStreamSkipNBytes

SUGGESTION

Simplification

Suppression

Suppress false positives by adding the suppression annotation @SuppressWarnings("InputStreamSkipNBytes") to the enclosing element.

Disable this rule by adding -XepOpt:Refaster:NamePattern=^(?!InputStreamRules\$InputStreamSkipNBytes).* as compiler argument.

Samples

Shows the difference in example code before and after the Refaster rule is applied.

 void testInputStreamSkipNBytes() throws IOException {
-    ByteStreams.skipFully(new ByteArrayInputStream(new byte[0]), 0);
+    new ByteArrayInputStream(new byte[0]).skipNBytes(0);
   }
