use of org.apache.phoenix.exception.UndecodableByteException in project phoenix by apache.

the class LengthFunction method evaluate.

@Override

        ptr.set(ByteUtil.EMPTY_BYTE_ARRAY);
        return true;
    }
    int len;
    if (child.getDataType() == PChar.INSTANCE) {
        // Only single-byte characters allowed in CHAR
        len = ptr.getLength();
    } else {
        try {
            len = StringUtil.calculateUTF8Length(ptr.get(), ptr.getOffset(), ptr.getLength(), child.getSortOrder());
        } catch (UndecodableByteException e) {
