示例1: CompositeBytesReference
public CompositeBytesReference(BytesReference... references) {
this.references = Objects.requireNonNull(references, "references must not be null");
this.offsets = new int[references.length];
long ramBytesUsed = 0;
int offset = 0;
for (int i = 0; i < references.length; i++) {
BytesReference reference = references[i];
if (reference == null) {
throw new IllegalArgumentException("references must not be null");
}
offsets[i] = offset; // we use the offsets to seek into the right BytesReference for random access and slicing
offset += reference.length();
ramBytesUsed += reference.ramBytesUsed();
}
this.ramBytesUsed = ramBytesUsed
+ (Integer.BYTES * offsets.length + RamUsageEstimator.NUM_BYTES_ARRAY_HEADER) // offsets
+ (references.length * RamUsageEstimator.NUM_BYTES_OBJECT_REF + RamUsageEstimator.NUM_BYTES_ARRAY_HEADER) // references
+ Integer.BYTES // length
+ Long.BYTES; // ramBytesUsed
length = offset;
}
示例2: ramBytesUsed
public long ramBytesUsed() {
return RamUsageEstimator.NUM_BYTES_LONG * data.length + RamUsageEstimator.NUM_BYTES_ARRAY_HEADER + 16;
}
