List of peekNextEntry() Examples

Examples of peekNextEntry()

com.fasterxml.util.membuf.ChunkyBytesMemBuffer.peekNextEntry()
Method that will read, and return (but NOT remove) the next entry, if one is available; or return null if none available. Method is idempotent.
Note that implementations may require additional storage for keeping track of recently peeked entry; for example, they may retain a byte array copy of the contents separate from physical storage.

Examples of com.fasterxml.util.membuf.ChunkyBytesMemBuffer.peekNextEntry()

       assertEquals(6, buffer.getEntryCount());
       assertEquals(21, buffer.getTotalPayloadLength());
       assertFalse(buffer.isEmpty());


       // then peek, read/skip
       byte[] chunk = buffer.peekNextEntry();
       Assert.assertArrayEquals(buildBytesChunk(1), chunk);
       assertEquals(1, buffer.skipNextEntry());


       assertEquals(2, buffer.getNextEntryLength());
       chunk = buffer.peekNextEntry();
